Reflection AI introduces Beam, an agentic open model with 501B total parameters and 23B active parameters. The company says Beam offers frontier reasoning efficiency, advances the Western open frontier on coding and agentic tasks, and was trained end-to-end from scratch. Full weights are set for release this month.
The chart compares Beam against Chinese and Western open models on coding, agentic, and reasoning benchmarks, showing where it leads and where it trails.
