Reflection has released **Beam**, a 501-billion-parameter open-weight Mixture-of-Experts model designed for advanced coding, reasoning, and agentic workflows, available on Hugging Face under an Apache 2.0 license. Alongside the model weights, Reflection launched an ecosystem of over 40 partners to support deployment, as well as the open-source **Mirror CLI** coding harness to help developers build and manage agentic systems efficiently.
Beam is now available. Make intelligence open and accessible to all.
