## Verdicts

**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.

**OpenAI Image API.** Generation, mask edits and multi-reference edits on the same models, via the Image API or the Responses tool. No per-image price for GPT Image 2.5, and the cost calculator doesn't cover it.

## Before you call either

### 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

### OpenAI Image API

1. Pin `quality` and `size`. `auto` makes cost and latency vary per call
2. Read `usage` in the response to track image tokens, it's the only cost signal for GPT Image 2.5
3. Don't retry `moderation_blocked` or `image_generation_user_error`. Change the prompt first
4. Honour `Retry-After` on 429 and add jitter, image limits are per minute and low at tier 1
5. Move off gpt-image-1 before 2026-10-23 and off 1-mini, 1.5 and chatgpt-image-latest before 2026-12-01
