Reflection AI has introduced Beam, its first open-weight model, targeting developers building coding assistants and autonomous agents. The architecture is a sparse Mixture-of-Experts design with 501 billion total parameters, of which 23 billion are active during inference.

The model is released under the Apache 2.0 license, allowing commercial and research use. Reflection AI states that Beam matches the reasoning capabilities of GLM-5.2 while requiring significantly less compute for inference, reportedly three to four times lower.

By focusing on coding and agentic workloads, Beam enters a competitive space alongside other open-weight models. Its MoE design aims to deliver large-model performance at a lower operational cost, which could benefit teams deploying AI agents in production.

The release adds to the growing pool of open-weight models optimized for specific tasks. If the claimed efficiency holds, Beam may appeal to organizations seeking capable coding and agent models without the full cost of dense alternatives.
