About

Reflection Beam 1.0 is an open model released on 16 Oct 2026 under the Apache 2.0 license. It is made by Reflection. Its maker put the full weights online, so anyone can run it if they have the hardware. Few have, because it needs about 300GB even at 4-bit. On OpenCode it is free and has no request cap for a limited time.
