## Verdicts

**Adobe Firefly API.** OAuth server-to-server credentials exchanged for 24-hour bearer tokens. Enterprise contract only. No self-serve sign-up and no public price list.

**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

### Adobe Firefly API

1. Call the REST async endpoints directly. `@adobe/firefly-apis` 2.0.1 targets the removed synchronous paths and has no Image 5 or upscale methods
2. Cache the IMS token and refresh it before its 24 hours run out
3. Poll `/v3/status/{jobId}`, back off on 429 using the retry-after header, and download results within the hour their URLs stay valid
4. Send `precise_upsampler_v1` to Upscale. `creative_upsampler_v1` returns 422 since 2026-04-24
5. Image 5 lives at `/v4/images/generate-async`. Image 3 and 4 stay on `/v3/images/generate-async`

### 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
