Nathan Lambert 转评 @alexandr_wang 发布的 muse spark open，称其为迄今最强的美国开放权重模型：816B 总参数、42B 激活、1M token 上下文、原生多模态，面向编码和长程任务等智能体工作。他认为若实际表现与跑分相符，该模型采用率将暴涨，是美国首个具备接近前沿智能体能力的开放权重模型，并提到此前 GLM 5.2 与 Kimi K3 代表了中国模型的那次跃升。

If it performs roughly what like the scores indicate, adoption of this model is going to go gangbusters. First open-weigh model in the US with near frontier agentic capabilities (GLM 5.2 + Kimi K3 was that step change from China). US models get crazy adoption.
1/ muse spark open is the most capable US open-weight model to date. 816B total params, 42B active. 1M-token context. natively multimodal. built for coding and agentic work like long-horizon tasks, hard software engineering, multi-step reasoning. america! 🇺🇲在 X 查看被引用的帖子
