Beam
3 storiesBeam can refer to two things: the open-weight model from Reflection AI, or the Erlang virtual machine, BEAM. Recent coverage centers on Reflection AI releasing its first open model, Beam, on Hugging Face: a 501B-parameter MoE with 23B active per token, a 1M-token context window, and an Apache 2.0 license, aimed at coding and agentic use, with day-0 support in transformers, SGLang, and vLLM. A separate story covers Imp, a port of DSPy to Elixir/BEAM.
