Muse Ember introduces lower-priced API access for repeated agent tasks
Meta announced Muse Ember in its API and coding product, with lower listed token rates for short prompts and a higher tier beyond 200,000 tokens.
Why it matters
Repeated extraction, routing and coding subtasks may become cheaper when a smaller model can meet the required quality.
What to watch
Independent task-level cost comparisons and observed reliability under the same prompts and tools.
Still uncertain. Task-level savings depend on tokens, retries and accuracy. Access and reported benchmarks were not independently tested.
Impact assessment reviewed 2026-11-10.
- Who it helps
- Teams comparing cost and quality for repeated agent tasks.
- Availability
- Meta’s November 9 announcement lists muse-ember-1.0 in the Meta Model API and Muse Code. Account and regional access were not tested.
Price depends on prompt length
For prompts up to 200,000 tokens, listed input/output rates are $0.10/$0.50 per million tokens. Above that threshold they rise to $0.30/$1.50. Reasoning and output volume still affect the total cost of a task.
Evaluate on your own work
The announcement mixes external benchmark results and internal evaluations, with different testing setups. A lower token price or benchmark score does not establish lower cost for every completed workflow.

Where the evidence stops
No API request or billing test performed. Published comparisons were not independently reproduced; the model is not established here as an open-weight release.
