## 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.

**Qwen-Image 2.1 (Model Studio).** qwen-image-2.1-pro generates and edits images with up to 10 references and transparent output, at $0.04 an image in Singapore, through an OpenAI-compatible endpoint or DashScope. Model Studio publishes a 99.9 per cent SLA and a no-training statement. The model allows 20 requests a minute, has no OpenAPI file, and its open weights are for non-commercial use only.

## 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`

### Qwen-Image 2.1 (Model Studio)

1. Use the same region for the key, the model and the endpoint. Cross-region calls fail
2. Download each result within 24 hours. The URL expires and the image is purged
3. With the OpenAI SDK, pass `image`, `seed`, `prompt_extend` and `watermark` through `extra_body`, and write size as `1024x1024`, not `1024*1024`
4. Set a client timeout of up to 600 seconds for several outputs, or use the async DashScope call and poll the task id
5. Do not send `prompt_extend_mode: agent` with input images. It returns 400
