Access
Standard serving tier in Cursor. Paid-plan usage pool and account policies apply.
Regions
Default model-specific processing region not established. Enterprise US-only residency can cover Composer when configured; external integrations have separate boundaries.

OUTPUT / 1M TOKENS$2.50
standard Composer 2.5 tier; Fast is the product default. Published additional-usage token rates beyond plan allowances. Model-token subtotal only, not a complete agent-run or subscription bill. Cache-write fee/TTL not established. Cursor's third-party Token Rate does not apply to Composer. Cached input price: $0.20 / 1M tokens (base tier).
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.

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.
