NVIDIA GTC was the highlight of last month for us. Our extensive participation included being a platinum sponsor, a strong presence with the booth, two tech talks, interviews with our leaders, partners and customers, and much more.

We’re excited to announce our integration with SkyPilot, an open-source framework that simplifies running AI and batch workloads across cloud platforms. This collaboration enables direct access to Nebius AI Cloud resources via SkyPilot.

Managed Service for MLflow becomes generally available — which means it gains more stability, a newer version of the platform, service level agreements and a service fee.

Today, we’re excited to announce that JupyterLab is now available in our Standalone Applications service, running on NVIDIA GPUs on our cloud platform. This fully managed offering eliminates infrastructure complexities, allowing you to focus entirely on your AI and machine learning (ML) projects.

In this blog post, we’ll demonstrate how to fine-tune an LLM using Nebius AI Studio with a function-calling task as our running example. The goal isn’t to achieve state-of-the-art results but to walk you through the steps and showcase why fine-tuning matters.

Speeding up computational tasks is critical to push the boundaries of science and ensure scalability and efficiency. Check out how NVIDIA Hopper GPUs available on Nebius AI Cloud performed against CPU workflows to accelerate homology research, deep learning-enabled protein embeddings and ML clustering.

On March 13, 2025, a release of one of the control plane components of the VPC service in the eu-west1 region caused massive networking issues for clients' pods of Managed Services for Kubernetes.

We are excited to unveil our latest collaboration: Nebius AI Cloud, the ultimate cloud for AI innovators, and Outerbounds, an AI/ML platform powered by the popular open-source framework Metaflow, are now integrated as part of a broader technology partnership.

In February, we at Nebius were busy preparing several new data center regions and working on our large-scale participation in NVIDIA GTC. We also rolled out some improvements to the platform and contributions to open source — as well as new initiatives to support AI research: a brand new biotech award and a research credits program.

We’re thrilled to announce a major upgrade to our US-based compute capacity. To bring it to life, we’ve joined forces with DataOne, an AI hosting infrastructure company, to ensure that the first phase of the New Jersey facility goes live this summer. We’re also launching a colocation facility in Iceland with Verne, a provider of sustainably powered data centers across the Nordics, and expect it to go live this month.

Generative AI and LLMs require immense computational power, making compute clusters essential for efficient scaling. Training and fine-tuning these models exceed the capacity of a single compute node, and parallel computing enables businesses to handle GenAI workloads at scale. In this article, we explore what compute clusters are and how to choose the right one for your needs.

Images with pre-installed drivers in our Managed Service for Kubernetes enhance NVIDIA GPU cluster scalability and reduce compute node start-up time by 2-3x.

Preparing a GPU cluster requires some effort and careful attention from your engineering team. It can become a significant challenge in terms of deploying and configuring a compute environment. Today, we’re happy to announce a small yet meaningful enhancement that makes the cluster preparation process much easier and faster.

Modern AI systems require substantial computational power to train and infer complex models. Cloud GPUs provide scalable infrastructure with high parallelism, offering access to virtualized GPUs through APIs and cloud platforms. The article delves into the technical aspects of cloud GPUs including virtualization, elastic scaling and management of high-performance workloads.

Repetitive employee queries can overwhelm HR departments and reduce time for strategic tasks. At Nebius, we implemented an AI Assistant powered by Nebius AI Studio that automates over 150 monthly queries. In this article, we explore how NLP and RAG help Studio drive such processes efficiency.

Explore what tokens are, how they enable AI models to understand and process language, represent text in AI systems and why tokenization is critical for LLMs. This post will also allow you to understand different tokenization techniques, how they affect processing efficiency and how modern NLP models like transformers use them to deliver accurate and context-aware responses.
