Always-on agents

Built for agents that don't stop with reliable tool-calling, persistent state across restarts, and self-managed memory across hours-long sessions.

Optimized for local deployments

It's small enough to run on a single consumer GPU or Mac, enabling use cases that range from local agents to local coding.

Benchmarks

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