Data & enterprise terms
With Privacy Mode enabled, code is not used for training by Cursor or model providers. Custom-model inference providers may process it. Cloud Agents store encrypted repository copies during execution, with deletion after completion described by the provider. These claims do not establish unconditional zero retention for every feature or account.
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
Cursor describes its own post-trained coding model, distributed through its product. Composer 2 is described among proprietary models in its technical report. Private classification for other Composer generations is inferred from this product/research lineage; their exact weight license is not published in the reviewed sources. Public Kimi K2.5 base weights do not constitute a release of the Composer derivative.
