## Summary

Meta introduces Muse Ember, its smallest and most efficient model, built for complex reasoning execution and everyday agent work. The model can carry workflows across apps, call tools in sequence, run tests and make targeted code fixes. It has a 1M-token context window and natively understands text, images, audio and video.

## Why it matters

The post names Muse Ember's agent and coding abilities, its 1M-token context window, and its multimodal inputs, which show what a small model can handle.

Today we're introducing Muse Ember, our smallest and most efficient model, built for complex reasoning execution and everyday agent work.

Muse Ember can carry workflows across apps, call tools in sequence, run tests and make targeted code fixes. With a 1M-token context window and native understanding of text, images, audio and video, it can also work across large document sets and varied inputs.
