Beam announcement, open model with 501B parameters and 23B active, full weights to be released later this month, undergoing final red-teaming and evaluations, focus on coding and agentic performance

Beam has announced an open model with 501B parameters, 23B of which are active. The full weights are slated for release later this month, following final red-teaming and evaluations. This model emphasizes coding and agentic performance, demonstrating 3-4x greater efficiency than GLM 5.2 and over 4x more efficiency than leading Western open models, completing tasks faster and at a lower cost.
