Data & enterprise terms

The March 30, 2026 service terms retain provider IP and allow use of inputs and generated content to provide, maintain, develop and improve the service. This review does not establish a no-training or zero-retention guarantee.

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

Inferred closed-weight service variant: the exact model is documented through MiniMax service access and no corresponding weight release was identified in the reviewed official MiniMaxAI repository inventory. Service terms reserve underlying IP. Public M-series, H3 and Music 3 weights are explicitly excluded; the OpenAPI MIT label licenses documentation, not model weights.
