## Verdicts

**Ideogram API.** Text rendering and layout control are the model's focus. Six API incidents in 90 days, three on v3 endpoints between 23 and 29 September.

**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

### Ideogram API

1. Send multipart form data, not JSON
2. Treat 402 as no credit or no payment method, and 422 as an unsafe prompt to rewrite, not retry
3. Check `is_image_safe`. When it's false the `url` is empty
4. Download images straight away, the links expire
5. Use the `/async/` variants with `webhook_url` for batches and verify the Ed25519 signature

### 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
