Rate conditions

  1. Resolution and generation mode determine the rate. Draft and enhancement calls are separate; the generation is not realtime streaming.
  2. HD draft generation. Full-quality enhancement is a separate charge.
  3. HD continuation draft. Full-quality enhancement is a separate charge.

Data & enterprise terms

Retention, training use, regional processing and enterprise terms have not been summarized for this endpoint.

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.

Lifetime & refresh

How to enable it
Generate with draft=true, download draft_cache, then submit mode=draft_enhance with the bundle.Source for How to enable it (opens in a new tab)
Usage fields
The saved generation is replayed at full quality rather than reinterpreting the prompt.Source for Usage fields (opens in a new tab)
Billing rules
Draft and full-quality generation use separate published rates.Source for Billing rules (opens in a new tab)

No prompt-cache discount or storage rate is claimed.

Limits & data boundaries
Enhancement uses the original generation inputs embedded in the bundle. Download before the signed URL expires.Source for Limits & data boundaries (opens in a new tab)

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

Classification inferred from the release-specific hosted/commercial offering, contrasted with BFL’s separately named public-weight releases and current official weight inventory. Paid access alone is not the criterion. No exact public checkpoint for this included release is present in the reviewed inventory; this is dated evidence, not a perpetual licensing claim.
