Reflection's Beam becomes the most capable open-weight model built outside China

Reflection has announced the launch of Beam, its first open-weight model. This mixture-of-experts system activates 23 billion of its 501 billion parameters per token and aims to match GLM 5.2 in coding and reasoning while using three to four times less compute. Reflection's strategy focuses on efficiency over raw performance to compete against Chinese rivals like Deepseek and Qwen. This approach allows the company to offer a competitive model in the global market while reducing operational costs.
