Reflection AI Introduces Beam: 501B-Parameter Agentic Open Model Coming to Ollama

Key Info

Reflection AI announced Beam, a highly efficient agentic open model with 501B total parameters and 23B active parameters, trained end-to-end from scratch, with full weights releasing this month. Ollama confirmed it will host the model as part of bringing more US-built models to its platform.

Highlights

• Beam has 501B total parameters with 23B active, positioning it as a highly efficient agentic model
• Targets frontier reasoning efficiency and advances the Western open frontier on coding and agentic tasks
• Trained end-to-end from scratch rather than fine-tuned from existing checkpoints
• Full weights are scheduled for release this month
• Ollama announced plans to bring more US-developed models to its platform
