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.

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

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

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
