Reflection AI released Beam-1.0-501B-A23B, a sparse Mixture‑of‑Experts model designed for coding, reasoning, and agentic tasks. The model has 501 billion parameters in total, with only 23 billion active at any time. It is available through Fireworks’ on‑demand deployment, which runs on dedicated GPUs without rate limits.
Why it matters
Developers can access a very large model for code‑related and reasoning work without the usual usage caps.
