Meta 发布 Muse Spark Open：美国最强开源权重模型登陆 OpenRouter
Meta 放了个 816B 的开源权重模型 Muse Spark Open，专攻智能体编程，1M 上下文还能吃视频和音频，OpenRouter 上已经能调，价格也便宜。
Meta（@AIatMeta）发布开源权重模型 Muse Spark Open，总参数 816B、激活 42B，采用 MoE 架构。模型定位编程与智能体任务，主打长时程任务、复杂软件工程和多步推理。上下文窗口达 1M token，原生支持文本、图像、视频、音频和 PDF 输入。该模型现已在 OpenRouter 上线，API 定价为输入 $1.25/M、输出 $4.25/M tokens，被称为迄今美国实验室最强开源权重模型。
Muse Spark Open from @AIatMeta is now available on OpenRouter! - strongest open-weight model from a US lab - built for agentic coding - 1M context - fully multimodal: image, video, audio and PDF input - $1.25/M in, $4.25/M out AI at Meta @AIatMeta Today we’re releasing Muse Spark Open, the most capable US open-weight model to date. Built for coding and agentic work, it excels at long-horizon tasks, complex software engineering, and multi-step reasoning. Key Model Specs: → 816B total / 42B active parameters → 1M token context window → Natively multimodal across text, image, video, audio 🔗 View Quoted Tweet 💬 5 🔄 3 ❤️ 24 👀 1540 📊 6 ⚡
