Reasoning
SupportedSource for Reasoning (opens in a new tab)

Task-specific reasoning is documented for the fine-tuning work. Public reasoning-effort controls are not.

Context caching
Not collected

No reviewed model-specific inference contract. Unknown does not mean unsupported.

Base model
Not collected

OpenAI collaboration is documented, but exact trained base versions and their relationship to the 2024 model are not established.

Do not infer that every family version has the same backbone or training method.

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

No public model API selector contract established.

Access
Commercial workspace access under an order form or approved trial. Exact underlying model versions require confirmation.
Regions
Model-specific processing and deployment regions not established.

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

Data & enterprise terms

The security page states that customer data is not used for training. Service Data is processed and retained under customer instructions, the MSA and applicable law. The privacy policy also describes query/response logging. Retention is not universally zero or a fixed duration, and it is not an inference-cache lifetime. Order forms control conflicts with the public MSA.

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.

Accordance platform

Not verified

No reviewed inference-cache contract. Project history, calendar state and service-data retention do not establish prompt caching.

How it works
Not collected

No reviewed inference-cache contract. Project history, calendar state and service-data retention do not establish prompt caching.

Minimum reusable input
Not collected

No reviewed inference-cache contract. Project history, calendar state and service-data retention do not establish prompt caching.

Lifetime & refresh
Not collected

No reviewed inference-cache contract. Project history, calendar state and service-data retention do not establish prompt caching.

How to enable it
Not collected

No reviewed inference-cache contract. Project history, calendar state and service-data retention do not establish prompt caching.

Usage fields
Not collected

No reviewed inference-cache contract. Project history, calendar state and service-data retention do not establish prompt caching.

No reviewed inference-cache contract. Project history, calendar state and service-data retention do not establish prompt caching.

Limits & data boundaries
Not collected

No reviewed inference-cache contract. Project history, calendar state and service-data retention do not establish prompt caching.

No verified cache rate for this endpoint. An empty rate is not a zero charge.

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

Provider documents a custom trained model family, with subsequent OpenAI reinforcement fine-tuning work and retained service intellectual property. Exact constituent checkpoints and public selectors are not disclosed.
