Reflection AI

Reflection has put Beam's weights under Apache 2.0, after a training run that peaked at 883,006 processor cores

Eleven days after announcing Beam without weights, Reflection has released them. The same day, AWS made the model available through SageMaker JumpStart in two US regions.

Reflection says its new open model matches GLM 5.2 on a quarter of the inference compute

The Nvidia-backed lab raised about $4.7bn to put a Western model back on the open-weight frontier. Its first release sits a point below GLM 5.2 on every test it published — and the pitch is the inference bill, not the score.
