# OpenAI Image API (slim)

> OpenAI's image generation and editing endpoints (/v1/images/generations and /v1/images/edits), also callable as a tool inside the Responses API.

- Full: https://www.anchorterminal.com/tools/openai-image-api.md (~6,300 tokens) · this version ~1,480 tokens · JSON https://www.anchorterminal.com/tools/openai-image-api.json · canonical https://www.anchorterminal.com/tools/openai-image-api
- Index: https://www.anchorterminal.com/llms.txt · API: https://www.anchorterminal.com/api/v1/index.json · Updated: 2026-10-04

**BB · 72.7/100 · rank #67 of 452 · #1 in Image generation · agent-ready · confidence high**


Assessment: 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 it

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
