Reflection AI 的 Beam 模型采用稀疏 MoE 以降低推理成本

Reflection AI 发布了 Beam 模型,这是一款开放权重模型,拥有 5010 亿总参数,但每次任务仅激活 230 亿参数。这种稀疏的专家混合(MoE)架构可显著降低推理成本,Reflection AI 声称其计算量比 Z.ai 的 GLM-5.2 等模型少 3-4 倍。虽然自报的基准测试在 SWE-Bench Verified 和 AIME 2026 上得分具有竞争力,但独立验证尚待进行。该模型计划根据 Apache 2.0 许可证发布,并且其美国注册地被认为是商业采用和数据主权的关键因素。 AI

影响 可能降低大规模代理部署的推理成本,使企业更容易获得先进的 AI。

    Reflection AI Beam:为何拥有 501B 参数且成本仅为 23B 的模型比排行榜更重要

    <p>Reflection AI's Beam, announced October 5, 2026, is a 501-billion-parameter open-weight model that activates only 23 billion parameters per task. The headline number is the 501B. The number that decides whether anyone actually deploys it is the 23B.</p> <p>That split is the wh…
