Verdicts

Black Forest Labs FLUX API

Per-image and per-megapixel prices published per model, from $0.014. Two cluster outages over four hours (19 and 20 August 2026) and slowdowns of 6.5 and 20 hours since.

fal image models

Hundreds of image models, including FLUX, Nano Banana, GPT Image, Seedream, Recraft and Ideogram, on one key. Billing units vary by model, per image, per megapixel or per token.

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

fal image models

  1. Fetch https://fal.ai/models/<endpoint-id>/llms.txt before calling a model to get its schema and price
  2. POST to https://queue.fal.run/<endpoint-id> and poll or pass a webhook, rather than holding a call open on fal.run
  3. Use an API-scoped key for agents. ADMIN keys can deploy and manage apps
  4. Download outputs you need to keep. CDN retention defaults to at least 7 days, set X-Fal-Object-Lifecycle-Preference to change it
  5. Validate inputs before submitting, a malformed request can still be billed
