## Which one, for what

### Bria API (B)

Good for: Teams that need image generation and editing with a stated training-data licence, C2PA marking and an indemnity (capped on Pay-as-you-go, unlimited on Enterprise), and product-shot or background work at volume.

Ahead on:
- Reliability, 83 against 70
- Schema & documentation, 84 against 66
- Payments & pricing, 40 against 20

Also in its favour:
- Runs on your own machine

Watch for: API keys are organisation-wide with no scopes, and no spend cap was found in the reviewed documentation

### Qwen-Image 2.1 (Model Studio) (B)

Good for: Low-cost image generation and multi-reference editing with transparent PNG output, for agents already on Model Studio or using the OpenAI Images protocol.

Ahead on:
- Security & auth, 75 against 33
- Maintenance & community, 77 against 69
- Transparency & trust, 66 against 49

Watch for: 20 requests a minute in every region

## Verdicts

**Bria API.** Per-image prices, 100 free calls without a card, OpenAPI files and Markdown docs make a first call quick, and the terms warrant that customer content is not used for training. Keys are organisation-wide with no scopes, and the API has no changelog or deprecation policy.

**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

### Bria API

1. Send the key in the `api_token` header, not as `Authorization: Bearer`. Only `/v2/image/verify` and `/v2/video/verify` work without it
2. Expect `202` with `request_id` and `status_url` from v2 endpoints. Poll `GET /v2/status/{request_id}` every 1 to 2 seconds, or pass `sync: true`
3. Status polls count towards the per-endpoint limit (10 a minute on Free, 60 on Pay-as-you-go), so prefer `webhook_url` for batches
4. Download results promptly. Image URLs expire after 3 days by default, and legacy `/v1/product/*` results after 1 hour
5. Do not resend a failed `POST` blindly. There is no idempotency key, and the SDKs retry status polls only

### 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
