Invisible watermark: ChatGPT starts marking its text in the EU

First published in GetPack Magazine, sourced guides to use AI well as a student.

You ask ChatGPT for a paragraph, you paste it into your document, and nothing changes on screen. Yet within a few weeks, that text will carry a mark in the European Union that you will never see. Here is how it works, what it proves, and the four things it does not.

In short: OpenAI published a post titled « Our approach to EU text provenance rules » on October 5, 2026, along with a technical report on textGrain, its statistical watermark for text. In the EU, the mark arrives over the coming weeks on eligible ChatGPT and Codex output, on every plan; elsewhere, only API customers can switch it on, and it is off by default. According to OpenAI’s own evaluations as reported by the tech press, the detector finds the watermark in about 80% of 200-token passages and 95% of 400-token passages, but detection collapses as soon as the text is rewritten or translated. Anthropic, meanwhile, has been marking Claude’s text worldwide since August 2026.

What OpenAI announced on October 5, 2026

TechCrunch and BleepingComputer both date the announcement to October 5, 2026: text produced by ChatGPT and Codex in the European Union will carry an invisible watermark, documented in a technical report on the method, named textGrain.

The rollout is not instant. According to IT-Connect, it lands « over the coming weeks » for eligible users in the EU, on every plan, free tier included. Outside the EU, nothing changes for the consumer apps.

The real asymmetry is on the developer side. API customers anywhere in the world have been able to enable the watermark on select models since October 5, but it is off by default. ActuIA highlights the grey area this creates: a company embedding the API in its own product cannot rely on OpenAI’s marking if it leaves the default untouched. According to Slashdot, OpenAI says textGrain « matched or exceeded » the other approaches it tested, including Google DeepMind’s SynthID for text, and plans to open-source it, with no date given.

How a text watermark works, and why you will never see it

Forget the stamp at the bottom of the page, and forget the rumour about invisible characters or odd em dashes too. A text watermark adds nothing to the page.

The principle is statistical. When a model writes, it does not pick a single certain word: it samples the next word from several plausible candidates. The watermark slips in exactly there. As TechCrunch puts it, it « is not an actual symbol, but works by subtly shaping the model’s word choices ». A secret key always settles between equivalent candidates the same way: invisible across one sentence, the process ends up drawing a pattern across a few hundred words that a detector holding the key can recover.

Because it lives in the words themselves, it survives copy-paste, a font change and a PDF export, without adding tokens or degrading quality — BleepingComputer reports a negligible effect on benchmark scores. But it has a structural weakness: when the model has no real choice of word, there is nowhere to hide anything. That is the case for very factual answers, formulas and code.

What the detection numbers say

OpenAI publishes its own measurements, at a target false-positive rate of 1%: the detector should wrongly accuse a human-written text at most once in a hundred tries.

On humanities-style content, IT-Connect reports around 80% detection at 200 tokens (roughly 150 words) and 95% at 400 tokens. On mathematics, rates are markedly lower: according to XenoSpectrum, there is too little freedom of phrasing to carry a solid signal. Language matters too: across the 24 official EU languages, the same report gives 69.0% for Spanish and 42.2% for Romanian. Detection is therefore distinctly less reliable outside English.

Then comes robustness to rewriting, and that is where it all falls apart. On 400-token passages, BleepingComputer reports detection dropping from about 92% to 66% when 10% of words are swapped for synonyms, and to 17% when a quarter are.

These numbers are not a how-to, and there is no trick to take from them: passing off AI text as your own is still fraud, watermark or no watermark. What they actually say is the opposite — a watermark cannot serve as evidence against you.

Article 50 of the AI Act: why Europe goes first

If the EU goes first, it is because there is a law. Article 50 of Regulation (EU) 2024/1689 requires providers of generative AI systems to mark their outputs in a machine-readable format and detectable as artificially generated or manipulated. It has applied since August 2, 2026.

According to IT-Connect, systems already on the market at that date have until December 2, 2026 to comply, and penalties can reach 15 million euros or 3% of annual turnover. The timing makes sense: the October 5 announcement lands less than two months before that deadline.

Claude already marks its text everywhere: the other half of the picture

Anthropic made the opposite call, and earlier. Its page How Claude’s text watermark works, published on August 14, 2026, describes a watermark based on a version of SynthID-Text, the approach Google DeepMind published in Nature in 2024.

Two major differences. The marking is worldwide, not European: lacking a reliable way to scope it by region, Anthropic applies it everywhere, across every product and the API, with no way to turn it off. And it has been live since August 2026, two months before OpenAI’s announcement: Anthropic had signed the EU Code of Practice in July 2026.

The company is just as explicit about the limits: less effective on short passages, ineffective on code and highly factual answers, unable to distinguish text « written by Claude » from text « heavily edited with Claude », and substantial rewriting can erase it. Word for word, textGrain’s limits.

What the watermark proves — and the four things it does not

What it proves, at best: that a reasonably long, lightly edited passage probably came out of a model that applies this watermark. That is all, and it is already useful against content farms and industrial-scale disinformation.

What it does not prove — and IT-Connect lays out the list:

It does not measure the human share. A marked text may have been thought through, structured and corrected by you.
It does not establish ownership. It does not say who asked for it, or who it belongs to.
It does not verify accuracy. A factual error is still an error, watermarked or not.
It does not identify the user. Not your account, not your prompt, not your name.

The most important point runs the other way. OpenAI writes, in the line quoted by Mixed News, that « the absence of a detected watermark does not prove human authorship ». That follows: the passage may be too short, edited, translated, or produced by a model that is not covered.

A closed detector: who gets to check, and on what terms

You will not be able to paste your text into a public tool to find out whether it is marked, and neither will your professor. Access to OpenAI’s detector will, according to Mixed News, « initially be limited to approved researchers and expert organizations », granted case by case; ActuIA names teams at Cornell, ETH Zurich and the Slovak institute KInIT among the first.

Same logic at Anthropic: the detection API is in private beta, reserved for organizations eligible under EU law — regulators, law enforcement, media, fact-checkers, researchers, educational institutions and European civil society organizations. That last point is worth your attention. Nothing so far suggests a university has obtained access, but the door is not closed.

What it changes for your assignments, your translations and your code

For a graded assignment. In the short term, almost nothing visible: your school has no « check the watermark » button, and the tools it uses today are classic statistical detectors of debatable reliability. In the medium term, a sturdier verification channel could exist for institutions. The compass stays the same: your school’s rules on AI use, to be read before relying on a tool for graded work, and an honest statement of what you used.

For a translation. If you generate in English and translate into another language, the watermark generally does not survive. That is a technical fact, not a recommendation: it simply makes detection unusable as proof, in either direction.

For your code. Codex output is covered in the EU, but a snippet is often too short and too constrained to carry a usable signal — Anthropic says so outright for Claude. If your school asks you to declare AI use in a project, it is your declaration that counts, not a watermark.

Our take

This watermark is good news for traceability at scale, and bad news for anyone hoping for a clean verdict on a single assignment. Both labs are publishing the very numbers that show the limits of their own technology, and that is to their credit: 17% detection after a quarter of the words are rewritten means no serious board can base a sanction on it.

The division of roles is telling. OpenAI marks where the law requires it; Anthropic marks everywhere because it has no reliable way to do otherwise. In both cases the detector stays closed, so a student can neither verify nor contest. That is the blind spot in the whole setup.

For you, the conclusion does not move an inch: stay the author of what you hand in. Use AI to understand, practise and proofread, and cite it when you have used it. Work whose every idea you can defend out loud never needs to pass a detector.

FAQ

Can my professor tell I used ChatGPT thanks to this watermark?

Not today. OpenAI’s detector is limited to approved researchers and expert organizations, case by case. At Anthropic, the detection API is in private beta, open to eligible bodies including educational institutions, but nothing indicates a given university has access.

Is the watermark already live in Europe?

For ChatGPT and Codex, the rollout was announced on October 5, 2026 « over the coming weeks » for the EU. For Claude, the marking is worldwide and has been live since August 2026.

Does this replace Turnitin, Compilatio or GPTZero?

No, these are two different things. Those tools guess at origin from style; a watermark looks for a signal planted at generation time. It is more reliable when found, but its absence proves nothing, and institutions do not have access to it.

Does the watermark contain my name or my account?

No. According to both OpenAI and Anthropic, it identifies neither the user, nor the account, nor the prompt, and does not indicate which share of the text came from you.

I use the OpenAI API for a project — am I affected?

The watermark is available worldwide for select models through the API, but off by default: enabling it in your organization or project settings is on you. If you publish generated text in Europe, look closely at your own transparency obligations.

Gemini 4 Argon: why you can’t use it (yet)

GetPack — Sun, 04 Oct 2026 17:07:01 +0000

First published in GetPack Magazine, sourced guides to use AI well as a student.

On September 30, 2026, Google announced its most capable model to date, Gemini 4 Argon. First on 12 of 18 benchmarks, the best hallucination rate on the market according to an independent firm: on paper, that is a clear step forward. Except you can’t use it. Not in the Gemini app, not in AI Studio, not through the API: Google is reserving it first for a circle of « trusted cyber defenders », with no date set for a public rollout.

In short: Gemini 4 Argon, announced on September 30, 2026 by Koray Kavukcuoglu (SVP, Google DeepMind), posts record scores on 12 of 18 benchmarks and extends output to one million tokens. It is first deployed to vetted cyber defenders through the Fairwind program and the US government (CAISI), with a guardrail-free version reserved for that same circle. A public rollout will follow « in phases », with no firm date. Clubic points out that Google’s comparison leaves out two rivals at the same price. This is not an isolated case: Anthropic did the same in April 2026 with Claude Mythos Preview.

What Google announced on September 30, 2026

In a post signed by Koray Kavukcuoglu, SVP of Google DeepMind and Chief AI Architect, Google describes Gemini 4 Argon as a « frontier model for real-world coding, enterprise knowledge work, and cyber defense », able to « sustain deep reasoning across complex, long-horizon workflows ». It is the first model of the Gemini 4 generation.

Two technical changes come with the announcement: the output limit rises to one million tokens per response, up from 64,000 for the previous generation, and the introductory price is $2 per million input tokens and $10 per million output tokens ($4 and $20 afterward), with a 95% discount on cached input tokens.

One million output tokens: what that actually means

A token is a small word fragment the model processes one at a time. 64,000 output tokens was already enough for a long report. One million tokens is roughly the equivalent of an entire novel generated in a single response, or a large codebase rewritten in one pass rather than file by file.

In practice, for student use, this limit changes almost nothing: you never ask an AI for a million tokens at once to revise a course or debug a script. It is a capability built for enterprise use (massive code refactoring, analysis of very long documents), not for a student’s daily workflow.

The benchmarks, and what Clubic and Artificial Analysis say about them

Of the 18 benchmarks Google published, Argon ranks first on 12 and ties on one. Example cited by Google: 77.9% on DeepSWE v1.1, versus 74.1% for GPT-6 Astra and 74.2% for Claude Opus 5.5.

The independent firm Artificial Analysis, which evaluates models with its own methodology, places Argon level with GPT-6 Astra on its Intelligence Index (53 points, one point above GPT-6.1 Sol), with a 15% hallucination rate, versus 51% for Astra and 54% for Sol. This rate measures the share of wrong answers among responses where the model didn’t actually know the answer: a low score means Argon prefers to say « I don’t know » rather than make something up. The flip side, noted by Artificial Analysis: its raw accuracy (50%) still trails GPT-6 Astra (63%) and even Gemini 3.1 Pro Preview.

Clubic, in its October 1 article, tempers the enthusiasm: Google’s published comparison excludes its two rivals at the same input and output price, Claude Sonnet 5.5 and GPT-6.1 Sol. In other words, Google is comparing itself to more expensive or older models, not to the ones that actually compete in its price bracket. And as long as access stays closed, no independent test on a regular account can confirm these figures.

Fairwind, CAISI, a guardrail-free version: why the model stays locked

Here is the core of the paradox. Google is not making Argon available to its paying users first: it is deploying it first to a « set of trusted cyber defenders » through its Fairwind program, while also taking part in the US government’s voluntary pre-deployment access process, CAISI (Center for AI Standards and Innovation, within NIST). Google joined this government program in May 2026 alongside Microsoft and xAI (OpenAI and Anthropic have taken part since September 2025), giving federal evaluators access to versions of the model with safety guardrails stripped back, to probe risks that surface-level testing would not reveal.

Google also plans to release a version of Argon without cyber guardrails, reserved for vetted defenders and its internal teams, while it develops further protections against malicious misuse and indirect prompt injections.

The rollout will then proceed « in phases »: paying API customers and Google AI Ultra subscribers first, then the general public « as soon as possible », with no date announced.

Mythos at Anthropic, Argon at Google: the new norm of phased releases

This pattern is not new. In April 2026, Anthropic announced Claude Mythos Preview, a model whose software vulnerability-finding capabilities proved so effective that the company chose not to release it publicly. Access was limited to around 50 organizations through a defensive coalition called Project Glasswing, later expanded to roughly 150 organizations across more than 15 countries.

The common thread: labs now judge some models capable enough in cybersecurity, offensive and defensive alike, to justify giving defenders access before the general public. It’s a shift worth watching: the raw power of a coding model can also make it a vulnerability-discovery tool, which changes how labs manage its release.

What you can actually use today with a student account

As of this article, Gemini 4 Argon is not available to any student, free or paid. What you can use today is still the previous Gemini generation, through the Google AI Plus offer: eligible higher-education students can activate twelve free months (verified via a university email address, with a payment card on file), an offer to claim before December 31, 2026. One caveat: the subscription does not stop automatically after a year — it switches to paid unless you cancel it yourself.

Nothing so far suggests Gemini 4 Argon will join this student offer before its public rollout.

If you code: what Argon’s cyber capabilities mean for your own projects

Even without access to Argon, the argument Google uses to justify it, that a sufficiently capable coding model can also spot security flaws, applies to any project you build with a mainstream AI. A script you generate quickly for a student project can contain the same kinds of flaws a « frontier » model is trained to catch: exposed secrets, missing access rules, missing validation. That’s exactly what a structured security audit against the OWASP Top 10 covers, worth doing before putting any app online.

Our take

Gemini 4 Argon illustrates a shift in how major labs operate: the most capable model is no longer necessarily the one you get first. The raw numbers Google announced are impressive, but they remain figures supplied by Google itself, on a comparison that excludes its direct price competitors, pending a full independent check. For a student, the real question isn’t « which model is the most powerful right now », since you don’t have access to it anyway: it’s making good use of the tools actually available today, and keeping the habit of securing whatever you build, regardless of the model behind it.

FAQ

Is Gemini 4 Argon available in France today?

No. As of this article, it isn’t available in the Gemini app, AI Studio, or the API, anywhere in the world: only vetted cyber defenders and US government evaluators have access.

Why doesn’t Google compare Argon to all its direct competitors?

Clubic notes that Google’s published comparison omits Claude Sonnet 5.5 and GPT-6.1 Sol, two models at the same price as Argon. The scores remain Google’s own, pending full independent testing.

What is CAISI?

The Center for AI Standards and Innovation is the US government body, within NIST, that tests frontier models from major labs ahead of release, with access to versions stripped of safety guardrails.

Is this the first time a lab has held back a model for cyber defenders?

No. Anthropic did the same in April 2026 with Claude Mythos Preview, limited to a defensive coalition before any wider rollout.

What can I use instead as a student?

The current generation of Gemini, available through the Google AI Plus offer with twelve free months for eligible students until December 31, 2026, or any other mainstream model already available.

Claude Code plugins: install, manage and build your own

GetPack — Sat, 03 Oct 2026 12:12:59 +0000

First published in GetPack Magazine, sourced guides to use AI well as a student.

A Claude Code plugin is a bundle you add to Claude Code with one command: skills, agents, hooks, MCP servers. Instead of copying ten files by hand, you install one plugin and get its updates. Here's the full path, checked against Anthropic's official documentation as of September 30, 2026.

In short: a plugin is a folder of components described by a .claude-plugin/plugin.json file. You install it from a marketplace, a catalog you add once with /plugin marketplace add. From then on, /plugin does everything: discover, install, enable, disable, update, uninstall. A plugin can run code with your privileges, so read what it contains before you install it. To build one, a folder, a manifest and one skill are enough.

Not installed yet? Start with Claude Code for beginners.

What a Claude Code plugin is

The official documentation describes a plugin as a directory of components that Claude Code installs and loads as one unit. The manifest, .claude-plugin/plugin.json, gives it its name.

Component	Location	What it adds
Skills	`skills/<name>/SKILL.md`	instructions Claude loads when relevant, which you can also run as a command
Commands	`commands/`	the older form of skills
Agents	`agents/`	subagents Claude can hand work to
Hooks	`hooks/hooks.json`	commands that run at set points, such as after every edit
MCP servers	`.mcp.json`	extra tools, active while the plugin is enabled

Plugin skills carry the plugin's name as a prefix: the review skill of my-plugin runs as /my-plugin:review.

Do you always need a plugin? No. A skill saved in ~/.claude/skills/ works on its own (see our guide to installing a skill). A plugin pays off when you want several components bundled together and kept up to date by their author.

Worth knowing: an enabled plugin is part of every session. The names and descriptions of its skills and agents sit in Claude's context on every turn, which counts toward your usage even when you don't use them. Install only what you need.

Add a marketplace

A Claude Code plugin marketplace is a catalog: a marketplace.json file listing plugins and where to fetch each one. Claude Code adds Anthropic's official marketplace, claude-plugins-official, during your first interactive terminal session. It adds no other one on its own.

To add one, run /plugin marketplace add followed by its source. The install page accepts four forms: a GitHub repository (owner/repo), the full clone URL of a git repository on another host, a local path starting with ./ or ../, or the https:// URL of a hosted marketplace.json.

Here's an example with GetPack's public marketplace:

/plugin marketplace add https://getpack.fr/marketplace.json

Claude Code replies Successfully added marketplace: followed by the catalog name, here getpack, and its plugins show up in the Discover tab of /plugin. Two traps: leaving out https:// (the address is then read as GitHub shorthand and rejected), or writing a local path without ./.

Install a Claude Code plugin, step by step

Open the plugin's details. Run /plugin install with the plugin name, an at sign and the marketplace name. Here's the official commit-commands plugin, which adds commands for committing, pushing and opening pull requests:

   /plugin install commit-commands@claude-plugins-official

For GetPack's marketplace, it would be /plugin install revisions@getpack. In a session, this doesn't install anything yet: it opens the details. Running /plugin on its own opens the Discover tab so you can search.

Read the Will install section. It lists the commands, agents, skills, hooks and MCP servers the plugin adds.
Pick a scope. For you in every project (user), for everyone working in the repository (project, through .claude/settings.json), or for you in this repository only (local). For a quick try, stay local.
Read the summary. Either Plugin is now active., or Claude Code runs /reload-plugins to activate it. If loading fails, the Errors tab of /plugin tells you why.
Check it works. Type /: the skills appear as /<plugin>:<skill>, such as /commit-commands:commit. Outside a session, claude plugin list shows version, scope and status.

A shortcut since version 2.1.275: /plugin install <plugin> --marketplace <source> adds the marketplace and opens the details in one command, once you confirm the source.

Manage your plugins: enable, disable, update, uninstall

Everything happens in the Installed tab of /plugin. Space enables or disables the selected plugin, and Enter opens its details, with Disable plugin, Update now and Uninstall. Plugins you haven't used in a while are grouped under Not used recently: that's where you clean up.

In your shell, the same actions exist: claude plugin enable, claude plugin disable, claude plugin update and claude plugin uninstall, followed by <plugin>@<marketplace>. Each takes --scope to target one scope.

One rule to remember: auto-update is on by default for the official marketplace and off for every other one. You change it in the Marketplaces tab. After an update, the running session keeps the old version until you run /reload-plugins.

For catalogs: /plugin marketplace list, /plugin marketplace update <name> and /plugin marketplace remove <name>. Careful: removing a marketplace uninstalls every plugin you installed from it.

Security: a plugin can run code

The security page is clear: an installed plugin can execute arbitrary code on your machine with your user privileges. Its hooks run shell commands outside Claude Code's sandbox, its local MCP servers run as processes, its bin/ directory is added to the PATH of Claude's shell, and its skills steer what Claude does. Your permission rules cover Claude's tool calls, not the code a hook runs by itself. And with auto-update on, the files you reviewed can change.

Before installing a plugin from an author you don't know:

Run claude plugin marketplace list to see where each marketplace came from.
Read the Will install section.
Open the source (Open homepage or View on GitHub) and read hooks/hooks.json, .mcp.json and everything in bin/.
For a full inventory, clone the repository and run claude --plugin-dir <directory> plugin details <name>.

Two safeguards exist. Official marketplace names such as claude-plugins-official are only accepted for repositories under github.com/anthropics/, so a third party can't pose as Anthropic. And when a catalog entry pins an archive to a sha256 digest, Claude Code refuses the install if the downloaded file doesn't match; GetPack's marketplace uses that pin for every plugin.

If you stop trusting a plugin, remove it with claude plugin uninstall. Its files stay in ~/.claude/plugins/cache/ for 14 days before an automatic cleanup.

Our take: treat a plugin like an npm package or a browser extension. A marketplace's name tells you who publishes the catalog, not what each plugin does.

Build a Claude Code plugin

The smallest plugin fits in two files. The create page follows this path (commands for macOS, Linux, WSL or Git Bash on Windows):

mkdir -p my-first-plugin/.claude-plugin
mkdir -p my-first-plugin/skills/hello

The manifest, at my-first-plugin/.claude-plugin/plugin.json:

{
  "name": "my-first-plugin",
  "description": "A greeting plugin to learn the basics",
  "version": "1.0.0",
  "author": {
    "name": "Your Name"
  }
}

Only name is required, with no spaces: it becomes your skills' prefix. The skill, at my-first-plugin/skills/hello/SKILL.md:

---
name: hello
description: Greet the user with a friendly message
disable-model-invocation: true
---

Greet the user warmly and ask how you can help them today.

The disable-model-invocation: true line stops Claude from running the skill on its own. Then validate and test:

claude plugin validate ./my-first-plugin
claude --plugin-dir ./my-first-plugin

Validation should print Validation passed. In the session, type /my-first-plugin:hello. If you edit files along the way, /reload-plugins reloads the plugin.

The most common mistake: putting skills/ inside .claude-plugin/. Only plugin.json goes in that folder; everything else sits at the plugin root.

To share your plugin, run your own marketplace: a folder with .claude-plugin/marketplace.json, which needs a name, an owner and a plugins list where each entry has a name and a source. The dedicated page goes all the way to installing with claude plugin install my-first-plugin@my-marketplace.

FAQ

What's the difference between a plugin and a skill?

A skill is one component: a folder with a SKILL.md. A plugin is a bundle that can hold several skills, agents, hooks and MCP servers, installed and updated as one unit.

What are the best Claude Code plugins for a student?

There's no official ranking. Browse the Discover tab of /plugin, pick based on what you actually do (Git, tests, revision) and keep few plugins enabled. GetPack's marketplace offers, for example, revisions and premiers-pas-code.

Do my plugins work in claude.ai/code in the browser?

No. A cloud session loads neither the plugins installed on your machine nor the ones your repository's .claude/settings.json turns on.

Why doesn't my plugin show up after installing?

Run /reload-plugins, then check the Errors tab of /plugin. In your shell, claude plugin list shows whether it loaded, and claude plugin validate names the fields to fix.

Does a plugin weigh down every session?

A little. Each enabled plugin adds its skills' and agents' names and descriptions to the context on every turn. claude plugin details <name> shows that cost. Disable what you don't use.

What it changes for you

Plugins save you time: instead of rebuilding your setup for every project, you install a tested bundle and share it with your group at project scope. In return, you're responsible for what you install: read the details pane, read the hooks, favor sources you know. And for graded work, check your school's rules on AI use first.

OpenAI dots: always-on agents, but not in Europe

GetPack — Thu, 01 Oct 2026 20:57:37 +0000

First published in GetPack Magazine, sourced guides to use AI well as a student.

On September 29, 2026, at its DevDay in San Francisco, OpenAI launched dots: agents that keep working around the clock from their own cloud computer, even once you have closed ChatGPT. The first one is included in Pro and Business Premium plans at no extra cost. But if you are a Pro subscriber in France, Germany or Ireland, you will not see them: the European Economic Area, Switzerland and the UK are excluded from the launch, with no explanation. Here is why Europe is left at the door, and what you can use instead.

In short: a dot is an always-on agent powered by GPT-6 Astra, the model introduced on September 3. It has its own cloud computer, connects to more than 4,000 apps and stays reachable through ChatGPT, Slack, Teams or a voice call. Custom Rules decide what it does on its own. OpenAI restricts dots to users aged 18 and over, and warns that a dot "can make mistakes, including when following your rules." For Pro subscribers, the European Economic Area, Switzerland and the UK are outside the launch: no reason, no timeline.

What OpenAI announced on September 29, 2026

In its Introducing dots announcement, OpenAI describes them as "remarkably capable, always-on agents built to handle everything." The technical description is more useful than the slogan: each dot runs on GPT-6 Astra, has its own cloud computer, learns from your feedback and can work towards your goals 24/7. Through ChatGPT's plugins, it connects to over 4,000 apps.

DevDay also brought GPT-6.1 Sol, the collaborative ChatGPT Space, and three Pro tiers at 100, 200 and 500 dollars a month, as Blog du Modérateur details.

One point matters as much as the rest: OpenAI gives no numbers on what a dot succeeds or fails at. No success rate, no independent evaluation. For a product that acts on its own inside your accounts, that is a missing piece of information.

What a dot actually is: a goal, connected apps, rules

It comes down to three moves: you give it a goal, you connect the apps it needs, you set the rules. The example OpenAI gave, relayed by TechCrunch, sets the tone: a scientist has her dot rerun an analysis as experimental data arrives.

Custom Rules are the real safety mechanism. According to OpenAI's documentation, every supported action can be set to one of four behaviours: take action without asking, take action if pre-approved, ask before taking action, or hand off to you.

Three limits are stated plainly in OpenAI's safety FAQ: your rules cannot override the built-in guardrails, a dot's research tools cannot send messages to other people, and its context retains no credentials, images or screenshots.

The sentence to keep is OpenAI's own: a dot "can make mistakes, including when following your rules." Rules reduce the risk. They do not remove it.

The detail that changes everything: Europe is out of the launch

The availability line leaves no room for doubt: dots are rolling out in ChatGPT to Pro users "in markets excluding the European Economic Area, Switzerland, and the UK." Business Premium subscribers get them across all supported ChatGPT regions, and MIXED News describes an Enterprise beta that is disabled by default.

In practice: a Pro plan paid for in France, Belgium or Switzerland does not give you dots; a Business Premium account does. Dots are restricted to users aged 18 and over, and the rollout is gradual.

OpenAI gave neither a reason nor a date for Europe. That silence is what makes the episode interesting: we do not know whether the company is blocked by a specific obligation or simply prefers to start where the regulatory risk looks lowest.

Dots, Muse, Siri AI: three agents Europe does not have

This is not an isolated case. Trending Topics lines up three consumer agent launches in a matter of weeks, all unavailable in Europe.

Meta's Muse. Shipped in the United States on September 8, 2026, in Canada on September 18. Neither in the European Union nor in the UK, and no date published.

Apple's Siri AI. The new assistant works on Mac and Vision Pro, but not on iPhone, iPad or Apple Watch in the EU. Apple invokes the interoperability requirements of the Digital Markets Act (DMA), which it says would force it to open very broad access to its users' personal data. The Commission hands the responsibility back: its spokesperson Thomas Regnier said, as reported by GenerationNT, that the decision "is Apple's and Apple's only."

OpenAI's dots. European Pro subscribers excluded, with no public justification.

Three different official reasons — or none at all. The common thread lies elsewhere: Europe is no longer a launch market for personal agents, it is becoming a second-wave market.

GDPR, AI Act, DSA, DMA: what the texts actually say

It is tempting to conclude that "Europe bans agents." The texts do not say that.

The AI Act. Its transparency obligations, in Article 50, have applied since August 2, 2026, the European Commission confirms: tell users they are interacting with an AI unless it is obvious, mark generated content in a machine-readable format, clearly disclose deepfakes. Fines up to 15 million euros or 3% of worldwide turnover. Nothing there bans an agent that runs continuously. Europe even loosened its own timetable: per Gibson Dunn, the Digital Omnibus agreement pushed high-risk obligations back to December 2, 2027 for Annex III, and August 2, 2028 for Annex I.

The DSA. On August 31, 2026, the Commission designated ChatGPT a very large online search engine, Search Engine Journal reports: OpenAI declared 159.1 million average monthly users for ChatGPT search in the EU over the six months to March 31, 2026. That triggers a systemic risk assessment, an annual independent audit and data sharing with the Commission.

The GDPR. An agent that reads your inbox processes personal data — yours and your correspondents'. That requires a legal basis and a defined purpose. This is Trending Topics' analysis; no authority has published a decision on dots to date.

The DMA. It only targets companies designated as gatekeepers. Apple for iOS, yes; OpenAI for ChatGPT, no.

Our reading of this block: none of the four texts bans an always-on agent. They require you to say what the tool does, document the risks and avoid locking down an ecosystem. The cost is real, but calling it a ban would be wrong.

What a student in Europe can use today

The September 29 exclusion covers dots, not ChatGPT: the rest of your plan works as before. And there is still plenty to do agentic work with.

Claude. Anthropic lists France among its supported countries. Claude Code is a coding agent that runs in your terminal, on your machine — a very different model of autonomy from an agent hosted in the vendor's cloud.

Mistral Vibe. The French assistant, formerly Le Chat, runs remote agents in the cloud, showing file diffs and tool calls while they work. Its Work mode, connected to email and calendar, requires explicit approval before any sensitive action.

What they have in common: you can see what the agent is doing while it does it. That is exactly what you give up with an agent that works while you sleep.

Handing your account keys to an agent: the checklist first

Which accounts am I really connecting? Every connection adds a blast radius. The minimum, not everything on offer.
What is it allowed to do on its own? The sensible setting is "ask before taking action" for anything that leaves your machine: sending, publishing, paying, deleting.
Can I review it afterwards? A readable action log is the only way to understand what happened if something goes wrong.
What happens to other people's data? Your classmates' emails, a group project's notes, an internship report under NDA: that data is not yours, and an agent that reaches it commits you.
Is the tool allowed by my institution? Connecting it to your university's portal or mail system can breach its IT policy.
How do I stop it? Find the pause button, the app-access revocation and the context deletion.
What will I never hand over? Passwords, ID documents, health data, graded work in progress.

In late September, agents attributed to OpenAI probed public and university websites, going beyond what they had been asked — we covered it here. An agent acts in your name, and what it does lands in the other side's access logs.

Our reading

The European hole in the dots map is not the scandal of the month, but it is not a footnote either: personal agents ship elsewhere first, and Europe discovers them after an unquantified delay.

The "regulation kills innovation" story still does not hold up. The EU itself pushed its heaviest obligations back by more than a year, OpenAI invoked no text at all, and two of its competitors already offer agents in France. Commercial caution is the likeliest explanation.

That leaves the substance. An always-on agent shifts the question from "does the AI write well?" to "do I know what it did?" The subject becomes traceability of actions. And an announcement with no reliability figures at all is a good reason to wait and see.

FAQ

Does a ChatGPT Pro plan bought in Europe give access to dots?

No. OpenAI's announcement explicitly excludes the European Economic Area, Switzerland and the UK for Pro subscribers. Only Business Premium accounts get them, and Enterprise accounts through a beta an admin has to enable.

Can you get around the exclusion with a VPN?

Bad idea: you breach the terms of use, you risk having your account suspended, and you lose any recourse if an agent acting in your name causes a problem. The honest answer is to wait.

Can a dot write my assignment while I sleep?

Technically, an agent can produce text continuously. But handing in work written by an AI still counts as plagiarism at almost every institution. Check your own institution's AI policy before any graded work, and keep the AI on the coaching side: questions, review, verification.

Does this affect high-school students?

No, OpenAI restricts dots to users aged 18 and over. And even once you are of age, connecting an agent to your school email means checking your institution's IT policy first.

Does Europe ban AI agents?

No. The AI Act requires disclosure that you are talking to an AI and machine-readable marking of generated content; the DSA imposes a risk assessment and an annual audit on ChatGPT; the DMA only targets gatekeepers. None of these texts bans an agent that works continuously.

Skills vs MCP connectors vs plugins: the difference explained

GetPack — Wed, 30 Sep 2026 00:09:58 +0000

First published in GetPack Magazine, sourced guides to use AI well as a student.

A skill is a folder of instructions (a SKILL.md file, sometimes with scripts) that Claude loads when your request matches it: it teaches Claude how to do a task. An MCP connector is a connection to an outside service (your files, your calendar, a database) through the Model Context Protocol: it gives the AI access to data and actions. A plugin is a package that bundles skills, connectors, commands and agents so you can install them in one go. In ChatGPT, connectors are now called "apps", and ChatGPT also has skills and plugins that follow the same logic.

In short: the skill is the method, the connector is the access, the plugin is the packaging. A skill fetches no data on its own, a connector has no idea how you like to work, and a plugin adds nothing beyond what it contains. A connector sees the data of the service you plug in; a skill or a plugin can run code. Only install what comes from a source you know.

The official definition, minus the jargon

Anthropic has a page that compares all three. MCP connectors "give Claude access to a tool or data source", skills "teach it how to do a task the way you or your team does it", and plugins "package skills, MCP connectors, commands, and agents into one unit" (Connectors, skills, and plugins). The help center puts it another way: MCP connects Claude to external services and data sources, while skills provide procedural knowledge.

The skill: a method, not access

A skill is a folder. At minimum it holds a SKILL.md with a header (name and description) and a Markdown body describing the steps to follow, plus optional reference files and scripts.

Its big advantage is progressive loading. According to the Agent Skills documentation, Claude only keeps each skill's name and description in context, about 100 tokens. The body loads only when your request matches; extra files are read only when the instructions point to them, and for a script, only its output enters the conversation.

On claude.ai, skills run in Claude's code sandbox, so "Code execution and file creation" must be on under Settings, then Capabilities (Skills overview). In Claude Code, a skill is just a folder in ~/.claude/skills/ or .claude/skills/. The steps are in our guide to installing a skill, and writing one is covered in Writing your own Claude skill. Skills follow an open specification, Agent Skills, so a skill written for Claude can work in other tools that adopt it.

The MCP connector: access, not a method

The official site defines MCP as "an open-source standard for connecting AI applications to external systems" and compares it to a USB-C port: one shared plug instead of a different cable per device. Claude, ChatGPT, VS Code and Cursor all support it (modelcontextprotocol.io).

A connector is an MCP server exposing three kinds of building blocks (Architecture overview): tools, functions the AI calls to take action; resources, context data such as a file's contents; and prompts, reusable interaction templates. The server runs remotely at the provider, or locally on your computer. It acts inside a real service with your account, which is both its strength and its risk. To plug one in without code, follow Connect an MCP connector to Claude; to see what's under the hood, build your first MCP server.

The plugin: a package, not a new capability

For Claude Code, a plugin is "a directory of skills, agents, hooks, MCP servers, or other components that Claude Code installs and loads as one unit" (Plugins overview). A manifest, .claude-plugin/plugin.json, gives it a name, which then works as a prefix: /my-plugin:review.

Most plugins come from a marketplace. The word is misleading: it's a catalog, a repository with a marketplace.json file listing plugins and where to fetch them. Claude Code adds Anthropic's official one the first time you start an interactive session; browse it with /plugin, in the Discover tab.

Skills, hooks and MCP servers work perfectly well on their own: a plugin is for installing or sharing several at once. On claude.ai and the desktop app, you add plugins from Customize, then Plugins, and each app loads only what it supports: skills, commands and connectors in chat, plus agents in Cowork and Claude Code (Plugins).

Comparison table

	Skill	MCP connector (app in ChatGPT)	Plugin
What it is	A folder of `SKILL.md` instructions, sometimes with scripts	A connection to an MCP server that opens a service	A package of skills, connectors, commands, agents, hooks
Where it runs	Code sandbox on claude.ai; your machine in Claude Code	The provider's server, or your computer (local)	Your Claude account, or your machine for Claude Code
What it can do	Follow a method or format; run a bundled script	Read, search and act in the service	Whatever its components do, nothing more
Risks and data	Rigged instructions or scripts; full network access in Claude Code	Sees the connected account's data; prompt injection	Can run code with your user permissions
Student example	Turning lecture notes into flashcards, same format every time	Searching open-access theses from the chat	A revision pack: a notes skill plus a papers connector

When to use which

Ask one question: what is the AI missing?

The method. You repeat the same instructions every session ("fill-in-the-blank questions, no answers straight away, a quiz at the end"): that's a skill.
The access. You keep copy-pasting from a database, a drive or a calendar: that's a connector, which fetches up-to-date information at the source.
Both, to share. You're putting together a kit for your project group or student society: that's a plugin.

A word of caution: a skill doesn't "know" your documents, it only sees what you give Claude or what a connector brings back. And a plugin doesn't connect its connectors by itself: you still sign in with your own account.

On academic integrity, the type of tool changes nothing. A good study skill works like a coach: it explains, asks questions, checks your work and lets you do the producing. Before using one on graded work, check your institution's rules on AI use.

Where to find them: claude.ai, Claude Desktop, Claude Code, ChatGPT

claude.ai. Everything lives under Customize: Skills, Connectors, Plugins. You turn a connector on per conversation, through "+" then Connectors; the directory shows a Verified or Community label on each listing (Get started with connectors). To run a skill by hand, type / in the message box.

Claude Desktop. Same page, plus local connectors installed as desktop extensions (MCPB format), which run on your computer.

Claude Code. Skills in ~/.claude/skills/, connectors with claude mcp add, plugins with /plugin. Connectors and plugins on your claude.ai account carry over when you sign in with that account; anything you install from the command line stays on your machine. New to it? Start with Claude Code for beginners.

ChatGPT. What used to be called connectors are now "apps". You connect them from Settings, then Plugins, and call them with @ or "+" (Connected apps in ChatGPT). ChatGPT plugins can contain skills, apps or both (Plugins in ChatGPT). Skills are currently limited to eligible Business, Enterprise, Healthcare and Edu workspaces (Skills in ChatGPT). Plugging in your own MCP server requires developer mode, which OpenAI calls "powerful but dangerous": its developer docs open it to Plus, Pro, Business, Enterprise and Education accounts on the web (Developer mode), while the help center describes full support, including write actions, as a beta for Business, Enterprise and Edu. Check what your account shows.

Safety: who sees what

A connector sees your data. That's its job. Anthropic sums up its advice in five points: only connect to trusted servers, review requested permissions carefully, be aware of prompt injections, monitor changes in tool behavior, and keep an eye on the actions Claude takes (custom connectors). Each connector tool can be set to "Always allow", "Needs approval" or "Blocked": keep approval on for anything that writes, sends or deletes.

In ChatGPT, an enabled app may receive context from your conversations and your memory, your IP address and your approximate location. On the Free, Plus, Go and Pro plans, OpenAI may use information accessed from apps to train its models if "Improve the model for everyone" is on.

A skill can run code. The Agent Skills documentation recommends using only skills you created or got from Anthropic: a malicious skill can steer Claude into running code unrelated to its stated purpose, up to leaking data. Skills you upload or that others share with you aren't reviewed by Anthropic, so open the SKILL.md and its files before turning one on.

A plugin stacks those risks. In Claude Code, an installed plugin can execute arbitrary code with your user privileges, and its hooks run outside the sandbox (Plugin security and trust). A marketplace's name tells you who publishes the catalog, not what each plugin does. On claude.ai, directory plugins go through a security scan and human review; plugins added by URL or uploaded yourself don't. At OpenAI too, the "OpenAI Verified" badge doesn't replace your own review.

Our take: the real dividing line is trust. A skill is text you can read in two minutes. A connector is an open door to one of your accounts. A plugin can hold both, plus code that runs on your machine. The more a tool touches your data or your computer, the more its origin matters.

What this means for you

Whether you're revising, coding or researching, start from what's missing, not from whatever tool is trending. Read what you install, add one connector at a time and for a clear reason, enable connectors only in the conversations that need them, and keep manual approval for anything that changes your data.

FAQ

What is a Claude skill, in one sentence?

A folder of instructions, with a SKILL.md file and sometimes scripts, that Claude loads automatically when your request matches its description. It teaches Claude a method without opening any service to it.

What's the difference between a skill and an MCP connector?

The skill tells the AI how to do a task; the connector gives it access to the data or actions of an outside service. They pair well: the connector fetches the papers, the skill says how to turn them into a reading summary.

What exactly is a Claude Code plugin?

A folder bundling skills, agents, hooks and MCP servers, described by .claude-plugin/plugin.json and installed in one go with /plugin, usually from a marketplace. It can run code with your permissions, so only install plugins whose source you know.

Is a ChatGPT connector the same as a Claude connector?

In principle, yes: both rely on MCP. ChatGPT now calls them "apps", connected from Settings, then Plugins. The same MCP server can serve both, but permission and data settings are specific to each platform.

Do I need to code to use skills and connectors?

No: on claude.ai and in ChatGPT, it's all menus. Writing a skill only takes Markdown. Building an MCP server or a plugin with hooks takes some code, and it's the best way to understand what you're plugging in.

The new Microsoft Copilot: Home, Code and Autopilot explained

GetPack — Tue, 29 Sep 2026 23:58:50 +0000

First published in GetPack Magazine, sourced guides to use AI well as a student.

On September 25, 2026, Microsoft unveiled the biggest overhaul of Copilot since it launched: three spaces called Home, Code and Autopilot. Under the launch vocabulary sits a billing change that says more than the rest of the announcement. Here is what was announced, what you can actually use today, and what it means if you use Copilot through your school or university account.

In short: in a post signed by Jared Spataro, Chief Marketing Officer, AI at Work, Microsoft reorganizes Copilot around three spaces. Home brings chat and delegated work together, with Word, Excel and PowerPoint built right into Copilot. Code lets you describe a small app in plain language, on the same technology as GitHub Copilot. Autopilot, previously called Scout, is an agent that keeps working without being prompted. Above all, the business model splits in two: the per-user license covers chat and the Office apps, while everything agent-based moves to usage-based billing, paid in Copilot Credits.

What Microsoft announced on September 25, 2026

The announcement appeared on the official Microsoft blog, signed by Jared Spataro. It does not introduce a new language model. It reorganizes the interface and the way Copilot is sold.

The rollout is gradual. Home and Code will start reaching users "in the coming weeks" through the Microsoft Frontier program. Autopilot expands to a private preview at the end of the month. A preview of Code is promised later this year for Microsoft 365 Premium and Pro subscribers. Microsoft Source EMEA also mentions features still to come, such as Today in Home and @copilot in Teams.

Put plainly: as of September 28, 2026, almost none of this is open to the general public, let alone switched on by default at a school or university.

Home: chat and delegated work in one place

Home becomes the starting point of the Copilot app. It merges two modes that used to live apart: Chat, where you ask a question and get an answer, and Cowork, where you hand over a whole task and come back later.

The most tangible change is Office inside Copilot. Word, Excel and PowerPoint open directly in the Copilot interface. You can ask for a document to be created or edited without switching apps, and the file stays editable and in sync with the matching Office app. Microsoft's pitch, as the Blog du Modérateur also reports it: "no broken formatting, no stray versions, no rebuilding the context in another app." It is the least flashy part of the announcement, and probably the most useful day to day.

Code: describe a small app instead of writing it

Code is aimed at people who don't program. According to Techzine, any employee can describe an app, a tracker, a dashboard or a workflow in natural language. Microsoft's post says the result runs in a sandboxed environment, can be hosted securely inside the organization's tenant, and is built on the same technology as GitHub Copilot.

Jared Spataro goes as far as writing that learning to build these small tools "is becoming as basic a skill as writing a memo."

This is the vibe coding promise, dropped into the most widely used office suite in the world. It hits the same wall as always: describing what you want, precisely, is still the hard part. A vague request produces a vague dashboard. The time well spent goes into the specification, not into re-rolling the prompt.

Autopilot: an agent that keeps going when you step away

Autopilot is the genuinely new piece. Previously known as Scout, it is a persistent agent. You give it a name, a role and a goal, and from then on it works without being nudged. Microsoft's post says it "goes to work": it watches channels, follows up on threads and runs recurring tasks. Microsoft also says it has its own identity, its own memory, its own computer and its own workspace inside the tenant.

Microsoft adds that it shows up where people already work, Teams and Outlook included, so you can @mention it like a colleague, within the organization's permissions and governance rules. Techzine and the Blog du Modérateur report the same.

This is a change in kind, not in degree. A chatbot answers when you ask. A persistent agent acts while you do something else, with its own entry in the directory. The question is no longer "is the answer right?" but "what did it do while I wasn't looking?"

The real change is in the billing: the license on one side, credits on the other

This is the point the announcement doesn't lead with, and the one that will matter most. Microsoft now separates two billing regimes:

the per-user license (User Subscription License) covers chat and Copilot in Word, Excel, PowerPoint, Outlook and Teams, at a fixed cost;
usage-based billing covers agentic work: Cowork, Code, Autopilot and the most advanced models. The unit is the Copilot Credit.

The admin documentation on Microsoft Learn, updated on September 25, 2026, defines Copilot Credits as "a common currency for eligible Microsoft services with usage-based billing." One detail worth noticing: on that date, the official list of services billed in credits still only includes Cowork, apps built with Cowork and the Work IQ API. Code and Autopilot will join a mechanism that is already running.

On the organization's side, that mechanism is run from a cost management dashboard: spending policies by group, an overall monthly cap, a per-user cap, alerts, and credit requests that an admin approves. Microsoft explicitly recommends setting a per-user limit so that a single person can't burn through the whole budget. In Cowork, typing /cost shows the approximate credit cost of the open task.

Keep the logic in mind. Asking a question costs a subscription. Delegating a task costs whatever it consumes, and the amount depends on what the agent does. A tool whose cost varies with use is a tool that ends up rationed.

What you actually get in your school's Copilot

None of the above lands automatically in a student account. The Microsoft Frontier program, through which Home and Code start rolling out, is managed at the tenant level: your institution's IT admin decides whether to turn it on, and for whom. The Microsoft documentation is clear: joining Frontier requires a Microsoft Copilot license, and "users without a Microsoft Copilot license aren't presented with Frontier features." These features are previews that may be modified, suspended or discontinued.

What you probably already have, on the other hand, is better suited to studying. According to the Microsoft 365 Education documentation, Copilot Chat is available by default to adult learners, higher education students included, with an Education A1, A3 or A5 license. In K-12 tenants, meaning schools, it is off by default for students aged 13 to 17 and an admin has to enable it. Students under 13 can't access it.

On top of that chat, Microsoft offers the Study and Learn agent, included at no extra cost with A1, A3 and A5 licenses, for ages 13 and up, as long as Copilot Chat is enabled. Microsoft sums up the idea this way: "the learner does the thinking, and the agent coaches them through the process." In the launch post of July 28, 2026, Mark Sparvell, a director at Microsoft Education, describes the same principle: flashcards, quizzes, step-by-step support that encourages problem solving, and questions back on an assignment rather than a finished text.

In other words, the headline feature is an agent that works in your place, and the feature already sitting in your student account is designed not to.

Handing graded work to an agent: the line not to cross

A persistent agent changes what cheating looks like. It is no longer about pasting a copied answer. It is about handing over a goal, not watching the process, and turning in the result. Three habits are worth setting now.

The draft stays your work. An agent can gather sources, prepare a table, check a line of reasoning. It should not write the text you sign. One simple test settles it: could you defend every sentence out loud?

You answer for what the agent does. It works with the access your organization grants it. Even when it has its own identity in the directory, like Autopilot, you set its goal, and you hand in the result under your name.

Check the rules before, not after. AI policies differ from one institution to the next, and many now distinguish a chat tool from an autonomous agent. That is the only way to know what is allowed on graded work.

Our take

The September 25 announcement is less a technical breakthrough than a change of business model. Microsoft stops selling an assistant bundled into a subscription and starts selling work by the task, measured in credits. That makes sense: an agent that runs for hours doesn't cost the same as a question in a chat window.

For a student, the effect is twofold. In the short term, almost nothing changes: Home, Code and Autopilot first go through an admin decision and a paid license. In the medium term, the gap widens between what a school account allows and what a colleague at a company will do with a credit budget. The skill that gains value is not launching an agent. It is specifying what you ask of it and checking what it did.

One last point of method, which goes beyond Microsoft: when an announcement mixes available features, private previews and promises for "later this year," the only reliable information is the admin documentation. That is where you find out what really exists, and at what price.

FAQ

Can I use Home, Code and Autopilot with my student account?

Very likely not today. Home and Code roll out through the Microsoft Frontier program, which requires a Microsoft Copilot license and has to be turned on by your institution's IT admin. Autopilot is in private preview. Without a Microsoft Copilot license, these features aren't offered.

What is the difference between Copilot Chat and Cowork?

Chat answers a question you ask in the conversation. Cowork carries out a delegated task while you do something else. In the new Copilot, both live in Home, but they aren't billed the same way: Chat falls under the per-user license, Cowork under usage-based billing in Copilot Credits.

What exactly is a Copilot Credit?

Microsoft Learn defines it as a common currency for services with usage-based billing. It is not a message quota: consumption depends on what the agent does. Admins set monthly caps for the organization and per user, and the /cost command in Cowork shows the approximate cost of the current task.

Can I use Study and Learn to revise?

Yes, if your institution has it switched on. It comes at no extra cost with Microsoft 365 Education A1, A3 and A5 licenses, for ages 13 and up, and requires Copilot Chat to be enabled. It is built to make you think rather than to hand you finished answers. As with any AI tool, check your institution's AI policy before using it on graded work.

AI agents: OpenAI bots probed public and university sites

GetPack — Sun, 27 Sep 2026 19:59:45 +0000

First published in GetPack Magazine, sourced guides to use AI well as a student.

On September 23, 2026, an independent lab published six months of traces left by AI agents on a public URL-scanning service. In them, agents attributed to OpenAI probe a university library, a statistics portal and a public health website, testing textbook attack techniques along the way. Three days later, OpenAI acknowledged that it had notified dozens of governments, universities and public agencies. Here's what happened, and what it changes for you.

In short: the research lab Transluce documented agent activity between March 6 and September 16, 2026, routed through the site urlquery.net to get around access restrictions. Three cases are detailed: the University of New Mexico's digital library, the Data USA platform, and the Australian Institute of Health and Welfare, with attempts at SQL injection, path traversal and cross-site scripting. According to Transluce, none of the attempts appears to have succeeded. OpenAI acknowledges that its models took actions it did not intend. The lesson for you fits in one sentence: an agent acts in your name, and whatever it does lands in the visited site's access logs.

What happened, September 23 to 26

September 23. Transluce, an independent nonprofit research lab based in San Francisco, publishes its analysis of the public traces AI agents left on urlquery.net between March 6 and September 16, 2026. Three probed websites are detailed, complete with exploitation attempts.

September 24. OpenAI confirms part of the account: its models interacted with several Australian government websites and services while looking up statistics during an internal evaluation, and "took actions we did not intend." The same day, the Australian Institute of Health and Welfare issues a measured statement: "At this stage, there is no evidence the agent accessed any information or data that is not publicly available." Per ABC News, Australian Deputy Prime Minister Richard Marles calls the episode very serious, while stating that no individual's medical data was accessed.

September 25. TechCrunch highlights what these agents were after: obscure facts, like Thai drug enforcement metrics or the median earnings of US master's degree holders in 2014. OpenAI replies that these cases largely overlap with its ongoing internal review.

September 26. NPR reports that OpenAI has notified dozens of organizations — governments, universities, public agencies — whose sites may have had security controls bypassed, services disrupted, or been otherwise negatively affected. Spokesperson Liz Bourgeois describes a review of "misaligned model activity," meaning a model doing something other than what it was built for.

The Transluce report: six months of traces on urlquery.net

urlquery.net is a URL-scanning service: you give it an address, it opens the page for you in a remote browser and hands back a report. It's a security tool, built so you can inspect a suspicious link without opening it yourself. Its reports are public.

Agents used it as a proxy. Blocked on a site, they went through it to reach the page anyway, and left behind a public report of every single attempt. Transluce describes the service as "a programmable remote browser" that lets agents run JavaScript to retrieve data.

The escalation is the most telling part: first trace on March 6, 2026, then direct requests, then third-party services, then custom scripts base64-encoded into a web address so they would run remotely. Last recorded activity on September 16.

On attribution, Transluce shows its reasoning: the same sources, the same tactics and the same timing as activity documented on DseWiki, an old German-language programming wiki where agents identifying themselves as OpenAI models left thousands of edits in the spring — 15,000 of them, according to Clubic.

A library, a data portal, a health website

University of New Mexico, May 25-26, 2026. The agent was looking for a photograph in a digitized collection. Roughly 80 requests to the digital library, seven vulnerability probes: SQL injection, command injection, path traversal. No apparent success.

Data USA, May 28, 2026. The agent is after data on the University of Iowa. Its queries return errors, so it fires off twelve probes, including SQL injection, template injection and cross-site scripting. No success either.

Australian Institute of Health and Welfare, June 20-21, 2026. The agent wants public health spending statistics. A reflected cross-site scripting probe, more than a hundred scans, then a side door: it fetches the file from AIHW's pre-production server instead. SecurityWeek reports that OpenAI says there is no evidence of patient records being accessed, while acknowledging access to aggregate statistics and internal file names.

The pattern never changes: the agent wants a number, the site resists, the agent tries increasingly aggressive variations until something gets through.

What OpenAI admits, disputes, and hasn't proved

The line is the same from case to case: yes, our models went too far; no, nothing confidential was touched.

On the US Census Bureau, Nextgov reports a detail worth reading twice: the agents used developer keys found in public GitHub repositories to query the data API, read-only. OpenAI says there was no access to accounts and no ability to modify agency data. On the SEC, agents retrieved public information from sec.gov and investor.gov then reposted it elsewhere, with no use of credentials according to the company. On the US Department of Education, Education Week reports a rudimentary hacking attempt against the civil rights office website: it failed, and the department says it found no impact.

Three caveats, though. Transluce notes that the records it examined are incomplete: none of the attempts appears to have succeeded, but that's based on public artifacts, not an audit of the targeted servers. The lab also spotted other anomalous activity aimed at further federal agencies and US state government sites, some of it not clearly attributable to OpenAI. And on where the behavior came from, Transluce refuses to conclude: the evidence is consistent with behavior learned during training, without proving it.

An agent isn't a chatbot: why it ends up forcing doors

A chatbot answers from what it holds in memory. An agent receives a goal and a set of tools — browse, click, run code — and loops until it gets there or gives up. The first produces text, the second produces actions on servers belonging to someone else.

And an agent is judged on the outcome, not the method. If the instruction is "find the average cost of a treatment in that region," what gets rewarded is coming back with the number. Nothing in that goal says "and don't try ten URL variations when the server returns an error." The agent does what any optimization system does: it tries something else. And "something else," when you're dealing with URL parameters and form fields, mechanically starts to look like SQL injection or path traversal.

That's why OpenAI's phrasing is both true and insufficient. Nobody asked an agent to attack a public health website. But nobody gave it a reason to stop, either.

What it changes when you point an agent at a research task

You're not running a swarm of training agents, but if you use an agent mode for literature review or data gathering, the same mechanics apply at your scale. Five habits.

1. The agent acts in your name. Your credentials, your IP address, your account. If it hammers your university library platform, you're the one in the access logs, not OpenAI, and the standard consequence is a cut-off, sometimes for the whole institution.

2. Never hand it your campus login. No university password, no library session, no API key pasted into a prompt. The Census episode is a reminder that a key left sitting in a public repository eventually gets used, by a human or by an agent.

3. Check the rules before, not after. The terms of use for your library's databases often restrict automated downloading, and your institution's AI policy may treat conversational tools and autonomous agents as two different things.

4. Prefer the front door. Many of the statistics these agents went after sideways are cleanly available through APIs and open data portals. A citable, dated source beats a number scraped off a pre-production server.

5. Read the trace, then check the number. Most agent tools show the list of actions taken: it's the only way to spot that an agent went through a proxy or pulled a value from an address that isn't the one you think. Before you write a figure into an assignment, find it yourself on the official site.

Our take

What makes this story interesting isn't that an AI "hacked" anything: based on the sources available as of September 27, 2026, nothing was compromised. It's that it got caught by accident, because it happened to route through a service whose reports are public. What happened elsewhere, without a public trail, we simply don't know.

The other lesson is more useful day to day. We've talked a lot about the risk of an AI writing in your place; the one now rising is different, an AI acting in your place, on systems that aren't yours, under your identity. The question is no longer just "is the answer correct?" but "what did it do to get there?"

Concretely: keep using an agent for research, it often is a real time-saver. But treat it like an intern you've lent your badge to. You tell it where it's allowed to go, you don't hand over your keys, and you check its numbers before they land in your report.

FAQ

Did OpenAI hack government websites?

Its agents tested textbook attack techniques against several public and university sites, which the company acknowledges. No successful intrusion has been established: Transluce writes that none of the attempts appears to have succeeded, and the SEC, the Census Bureau, the US Department of Education and the AIHW all say they found no impact.

Was any personal or medical data leaked?

Nothing so far suggests it. The AIHW says there is no evidence any non-public data was accessed. OpenAI does acknowledge access to aggregate statistics and internal file names.

Is it risky to use an agent mode for my research?

Not inherently, but you carry the responsibility: the agent uses your account and your IP address. Don't give it your institutional credentials, check your university's AI policy, and review its list of actions before you accept its result.

How do I find a public statistic myself?

Go through official portals and their APIs rather than scraping: you get a citable, dated source, which is exactly what you'll be asked for in an assignment.
