Account- and model-specific concurrency, counting queued and processing requests. Dashboard limits are authoritative; current guide describes HTTP 400 on saturation and no standard rate-limit or Retry-After headers.Source for Request quotas (opens in a new tab)
The introductory blog advertises 20 concurrent requests after key creation. This is not assumed to be every account or model limit.
Safe request retries
Optional Idempotency-Key: 1–255 visible ASCII characters without whitespace. Same account, endpoint, body and webhook reuse the original request ID; mismatches return 422. Read status_url for current state.Source for Safe request retries (opens in a new tab)
Generation submissions only. Replays are not new generations and are not prompt caching; no expiry interval is established.
Pricing coverage
Published USD model tariffs; authenticated /estimate/{model-path} gives a configuration quote. Example credits/usd values in shared documentation are illustrative, not this model’s rate.Source for Pricing coverage (opens in a new tab)
Billing basis
Separate prepaid API balance; consumer subscriptions do not fund API use. Failed, moderated and successfully canceled queued generations are refunded.Source for Billing basis (opens in a new tab)
Generic documentation describes credits; current model pages publish USD rates. No fixed credit-to-dollar exchange is inferred.
GET /models/higgsfield/ai-influencer/options is public while the model is visible/available; otherwise 404. Filter by tier and refresh selections when config_revision changes.Source for Preset catalog (opens in a new tab)
Reference guidance
Seed and variation index do not guarantee identical pixels; catalog changes can affect selections. Automatically generated seed is not returned as extra metadata.Source for Reference guidance (opens in a new tab)
Advanced controls
trait_variants requires appearance-v2 and choices. General IDs original/v1–v5; pr_centaur allows v1–v10. Animal choices index 0–4; private variant/species catalogs are not exposed by the options endpoint.Source for Advanced controls (opens in a new tab)

Rate conditions
Published medium-quality rate per generated sheet. Quality/resolution is not a public request control in this schema; no alternate quality rates inferred.
API content may be used for training unless the workspace opts out; processing can take 10 business days and is prospective. Enterprise agreements can differ. Request records remain while the account is active; generated files are available for at least seven days. Zero retention requires an eligible enterprise addendum. Partner/excluded-model policies can differ.
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 hosted creative workflow with a named API contract. The sources do not establish a separately released proprietary foundation checkpoint or its exact upstream model identity; it is counted as a managed component, not a new private base model.
