OpenRouter adds Reflection Beam 1.0 501B model

Reflection’s new open‑weight model for coding and long‑term AI workflows is now listed on OpenRouter.

NoteBy Published by Oossa: 1 min read

OpenRouter now lists Reflection’s Beam 1.0 model. The model is built for reasoning tasks like code generation and multi‑step agent workflows. It uses a sparse mixture‑of‑experts design with 501 billion total parameters but only 23 billion active per token. The context window can hold up to 1,048,576 tokens.

Why it matters

Developers can run larger, more capable reasoning models without paying for full 501 billion‑parameter costs.
