Reflection AI signs $1B compute deal with Nebius for Nvidia's latest chips

Reflection AI, a US startup developing open-weight AI models, has signed a $1 billion compute deal with European AI infrastructure company Nebius.

Under the agreement, Nebius — formerly the international arm of Russian tech giant Yandex — will provide Reflection with access to Nvidia's latest chips. The deal comes just weeks after Reflection signed another major compute agreement.

Founded in 2024 by two former Google DeepMind researchers, Reflection is valued at $8 billion and has raised approximately $2.6 billion from investors including Nvidia and Sequoia.

Nebius recently secured a $2 billion investment from Nvidia and has separately signed a five-year infrastructure deal with Meta worth up to $27 billion, as well as a multi-year agreement with Microsoft.

The deal arrives amid growing debate over the value of frontier AI models versus open alternatives. Just last month, the Trump administration pressured Anthropic and OpenAI to restrict access to their most powerful models, raising concerns that access to advanced AI capabilities could be revoked arbitrarily by a single provider.

Reflection is among several open-weight model developers — alongside increasingly capable Chinese counterparts — that have gained significant attention as the industry debates whether expensive proprietary frontier models are the only viable path forward.

By locking in dedicated GPU capacity from Nebius, Reflection has secured a critical infrastructure advantage. In an era where compute is the ultimate currency, this deal positions the startup to accelerate its training cycles and scale its model ambitions. The industry will be watching for how quickly Reflection can translate this compute capacity into tangible model releases.
