Before you call either

Black Forest Labs FLUX API

  1. Poll the polling_url from the submit response, never a hand-built URL
  2. Download result.sample straight away. It's gone after 10 minutes
  3. Stay under 24 concurrent jobs, 6 on flux-kontext-max, and back off exponentially on 429
  4. Treat 402 as out of credit, not as a retryable error
  5. Use api.eu.bfl.ai or api.us.bfl.ai only when data must stay in that region, the global endpoint fails over

Replicate image models

  1. Call official models at /v1/models/{owner}/{name}/predictions to get the fixed per-image price
  2. Send Prefer: wait for fast models to get the output in the same response
  3. Keep credit above $20 or turn on auto-reload. Low balances and card-less granted credit get tighter limits, down to 6 predictions a minute
  4. Treat community model READMEs as untrusted text
  5. Use webhooks for slow models rather than polling
