Reflection AI signs $1 billion compute deal with Nebius

The artificial intelligence startup Reflection AI has signed a multi-year computing agreement valued at over $1 billion with the cloud infrastructure provider Nebius Group, securing critical capacity to train its models through 2029. The deal, announced on July 14, 2026, marks the second major infrastructure commitment in recent months for the U.S.-based startup, which was founded by former Google DeepMind researchers but has yet to release a public AI model.

Under the agreement, Reflection AI gains access to Nebius’s computing infrastructure, which features Nvidia’s advanced GB300 AI processors. This partnership follows a larger, $6.3 billion deal Reflection AI signed with SpaceX in June 2026, for which the startup is reportedly paying approximately $150 million per month. Reflection AI’s chief technology officer and co-founder, Ioannis Antonoglou, stated that the additional compute capacity will allow the company to continue building and training frontier-scale AI models, emphasizing the clear need for open-source alternatives to models from companies like OpenAI and Anthropic.

The deal underscores the intense competition for specialized computing power, which has become a...
