6d agoReflection Releases Beam Open-Weight Model
The 501-billion parameter Beam model activates only 23 billion parameters per token. Reflection designed this mixture-of-experts system to match GLM 5.2 in coding and reasoning while slashing compute requirements by 75%. It prioritizes efficiency to compete with Chinese rivals like DeepSeek.
The Signal
Practitioners gain a high-reasoning model with lower inference overhead.
