New open-weights language and multimodal models from the major labs, as they land on Hugging Face — with size, license and reported results.
Reflection unveiled Beam, a text-only sparse mixture-of-experts model with 501 billion parameters (23 billion active) and a 1 million token context window; weights and a technical report are due later this month. Reflection says it matches Z.ai's GLM-5.2 on advanced reasoning with 3-4x less inference compute, a claim not independently verified.
