Access & pricing

Prices belong to an endpoint and billing tier. A provider listing does not guarantee access for every account or region.

Rate conditions

  1. Plan-level fee includes multiple models with shared usage limits, not a per-model or per-token price. Contributor mode defaults on; regional terms and taxes may vary.
  2. Plan-level fee with 80x Everyday usage, not unlimited requests or a cost-per-question rate.

Data & enterprise terms

Contributor requests may be used to train and improve Meta models. This includes earlier Standard content resubmitted as context. Muse Code subscriptions enable Contributor mode by default; disabling it governs future submissions. Retention is not assigned an invented fixed duration. Users can opt into Standard mode for future requests.

Caching

Caching can reuse earlier input processing. Availability, lifetime and billing depend on the endpoint. A cache hit still generates a new response.

01 / INITIAL INPUTProcess & retain

The system processes eligible input and retains reusable state.

02 / LATER REQUESTCheck available state

Reuse depends on matching input, session state and the cache policy.

03 / CACHE HITReuse & generate

Reusing state can reduce repeated work. Any charges follow the billing rules below.

What the measurements say

No benchmark observations have been added for this model. We do not turn a vendor description into a performance score.

Latency and throughput depend on the host, request size, reasoning settings and load. There is no measured speed or global usage figure in this record.

The record behind the model

Why it is included

Meta identifies this native Muse model in its research or hosted-model catalog. The reviewed release is available through provider-controlled service, subscription or research preview, without a released weight artifact in the reviewed inventory. The September Spark roadmap still describes its weight release as forthcoming. Open-weight Glimmer, SAM and Llama are excluded separately; hosted access alone does not turn those models into closed models.
