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.

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

Inferred closed-weight classification for this exact hosted MiMo release from the original release description and developer public-weight inventory. The matching weights were not found. Later MiMo V2.5/V2.6 language weights and MiMo V2.5 ASR are explicitly public and are not substituted for this release; public MiMo-Audio components do not establish public weights for the separate TTS service.
