Meet Muse Glimmer
Muse Glimmer is trained to deliver competitive agentic and coding performance, with multimodal perception built in.
Built for agents that don’t stop with reliable tool-calling, persistent state across restarts, and self-managed memory across hours-long sessions.
It’s small enough to run on a single consumer GPU or Mac, enabling use cases that range from local agents to local coding.

How to use Muse Glimmer
Create an account, describe a task, and let the model plan, call tools, and keep working.
Create your account and your 50 starter credits are ready to use.
Describe an agentic job — a coding change, a research run, or a long-horizon workflow.
The model calls tools, tracks context and prior results, and keeps working across hours-long sessions.
Check the results in your session, keep the agent going, or add credits when you need them.
