Access & pricing

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

API model ID
Not collected

Published model/product name, not a reviewed standalone API selector.

Access
Historical custom-model announcement or experiment. Current access to this exact derivative is unverified.
Regions
Harvey lists US, EU, Switzerland and Australia processing options across providers; actual availability varies by subprocessor and selected service. No universal region guarantee for this component.

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

Data & enterprise terms

The default platform agreement prohibits training on customer content/data and restricts subprocessor retention or human-review logging, with a cloud-storage exception. September 16, 2026 service terms override conflicting general terms for optional Covered AI Services: subprocessors may retain data, conduct specified reviews, or process it in different locations. Workspace retention settings also have feature exceptions. The exact rules for this component require its service configuration and customer agreement; do not infer universal zero retention.

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

Documented custom model or trained model family used in the commercial Harvey ecosystem. No public derivative weights or independently accessible checkpoint are established in the reviewed sources.
