Data & enterprise terms
The public Cadence privacy page explains DPA scope, including vendor processing for Cadence. It does not establish a ChipStack inference-specific retention, training-use or region contract.
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
Official OpenAI case study documents a privately trained reinforcement-fine-tuned model. No public derivative weights or exact standalone checkpoint selector established.
