OpenAI’s mission is to ensure that artificial general intelligence (AGI)—by which we mean highly autonomous systems that outperform humans at most economically valuable work—benefits all of humanity. We will attempt to directly build safe and beneficial AGI, but will also consider our mission fulfilled if our work aids others to achieve this outcome. Apply our API to any language task — semantic search, summarization, sentiment analysis, content generation, translation, and more — with only a few examples or by specifying your task in English. One simple integration gives you access to our constantly-improving AI technology. Explore how you integrate with the API with these sample completions.

Experience JinaChat, a pioneering LLM service tailored for pro users. JinaChat ushers in a new era of multimodal chat capabilities, extending beyond text to incorporate images and more. Delight in our offer of free short interactions under 100 tokens. Our API empowers developers to leverage long conversation histories and eliminate redundant prompts to build complex applications. Dive headfirst into the future of LLM services with JinaChat, where conversations are multimodal, long-memory, and affordable. Modern LLM applications often hinge on lengthy prompts or extensive memory, leading to high costs when similar prompts are repeatedly sent to the server with only minor changes. JinaChat's API solves this problem by letting you carry forward previous conversations without resending the entire prompt. This saves you both time and money, making it the perfect tool for developing complex applications like AutoGPT.

By using the best-performing model for each request, we can achieve higher performance than any single model. Martian outperforms GPT-4 across OpenAI's evals (open/evals). We turn opaque black boxes into interpretable representations. Our router is the first tool built on top of our model mapping method. We are developing many other applications of model mapping including turning transformers from indecipherable matrices into human-readable programs. If a company experiences an outage or high latency period, automatically reroute to other providers so your customers never experience any issues. Determine how much you could save by using the Martian Model Router with our interactive cost calculator. Input your number of users, tokens per session, and sessions per month, and specify your cost/quality tradeoff.
