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
