Access & pricing

Prices belong to an endpoint and billing tier. A provider listing does not guarantee access for every account or region.

Inception API

Provider source (opens in a new tab)
API model ID
Not collected

No exact callable model selector established for this offering.

Access
Original model demonstrated on a playground and in provider benchmarks. Current raw API selector is unverified.
Regions
Deployment-dependent; complete serving region inventory unverified.

Endpoint pricing has not been collected. Check the provider for applicable rates.

Data & enterprise terms

Terms permit using submissions for model training unless the user disables “Improve the model for everyone” in API Platform settings. The privacy policy uses purpose-dependent retention, not a fixed universal period. The FAQ says custom zero-retention arrangements are handled case by case; enterprise agreements may differ.

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

Inception’s own Trust Center describes the Mercury family as proprietary. Public API and enterprise deployment access do not establish public weights.
