Reflection AI
An American 'open frontier' lab. The plan is to pretrain a large MoE open-weights model on tens of trillions of tokens, add reinforcement learning, and sell to enterprises and governments that want non-Chinese open models. It started on autonomous coding (Asimov agent) and then widened.

- Now
- No open frontier model public as of 2026-10-04. The Information (2026-07-29) reports a first model this year and a larger one in early 2027. Signed a $1B Nebius compute deal (2026-07-14) weeks after a SpaceX compute deal.
