## 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
