Reflection open-sources 501B-parameter MoE model Beam
Reflection open-sourced its first model Beam on Hugging Face under the Apache 2.0 license. It is a 501B-parameter MoE model (23B activated per token), supports 1M token context, focuses on coding and agent scenarios, and is already available on AWS SageMaker JumpStart and HyperPod. The same day, Gemini 4 Argon topped ARC-AGI-3 with 97.5%, while China plans to add 23 key AI technologies including large models and agents to export controls.
