Muse Spark

Everything your build needs in a single, highly capable model. Now in public preview for US developers.

Meet Muse Spark

End-to-end agentic workflows

Build and orchestrate multi-agent workflows with one model — including computer use, which lets the model operate a computer the way humans do, navigating across apps and interfaces to complete long-horizon tasks.

Advanced coding capabilities

Muse Spark writes, reviews, and ships code with fewer steps and lower latency. Whether you're building coding agents, review bots, or using AI as a development partner, it's competitive with the best.

Native multimodal perception

Muse Spark perceives video, images, and documents, and its visual reasoning runs through a real execution environment instead of scripted steps. Feed it a screenshot or a clip and let it build, so you can focus on shipping features fast.

Muse Spark benchmarks

Muse Spark is trained to deliver competitive agentic and coding performance, with multimodal perception built in.
