Model overview
Muse Spark Open is a coding-optimized open-weight model. Trained specifically for agentic coding workflows, it delivers higher first-attempt accuracy, reliable tool calling, and deep codebase understanding across the repos developers...
The summary below is compiled from sources by an AI model, not our own testing. Verify selection decisions against original sources and your workload.
Key features
- 专为代理式编程工作流（agentic coding workflows）优化，提升首次生成代码的准确率
- 支持多模态输入（文本、图像、音频、视频），但仅输出文本
- 具备可靠工具调用能力与深度代码库理解能力
Limitations & considerations

Frequently asked questions
Muse Spark Open (Xhigh) 是否支持多模态输入？
是，支持文本、图像、音频和视频四种输入模态。
该模型能否直接执行代码或调用外部工具？
资料明确标注其具备‘reliable tool calling’（可靠工具调用）能力，表明设计上支持工具调用，但不等于自主执行。
其输出是否支持结构化格式（如 JSON）？
是，标签中包含 'structured_outputs'，说明支持结构化输出。
Do open weights permit free commercial use?
Not necessarily. Check the version license, commercial conditions and usage policies. Self-hosting incurs compute and maintenance costs.
Are these real-time billing prices?
These are timestamped source snapshots, not live billing prices. Check the channel for current versions, regions, discounts and billing methods.
