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.

The record behind the model
Why it is included
Provider documents this Luminous model as a hosted commercial model or research demonstration. No original Luminous weight release was found in reviewed official model/repository listings. This is a qualified review finding; public SDK code and other open-weight Aleph Alpha families do not release these weights.
