GPT Image is OpenAI's image generation model, supporting text-to-image and image editing. Through RunAPI, all GPT Image endpoints share one key and per-call pricing.
A single RunAPI API key unlocks the whole model catalog across all providers. No separate accounts to create, no API keys to rotate per integration, and no credential management overhead. Add a new model to your app by changing one parameter.
Per-call pricing in USD, billed monthly into a single invoice. No subscription tiers, no minimum spend, and failed generations are never charged. The pricing page and check_pricing API show exact costs before you commit to a model.
Typed schemas, parameter constraints, and setup notes are packaged in the model skill so your implementation starts from the right contract. The skill loads into Claude Code, Codex, Gemini CLI, Cursor, and VS Code — your agent knows the correct request shape before you write a line of code.
Text-to-image and image editing. Both accept detailed text prompts with compositional instructions.
GPT Image follows spatial layout instructions in your prompt — you can specify where objects appear, relative sizes, and arrangement within the frame.
3 fixed sizes up to 1536 pixels.
GPT Image 2 is the newer model with near-perfect multilingual text rendering and up to 4K output. GPT Image is the prior generation with strong compositional control.
Yes — the image editing endpoint accepts a source image and modifies it based on your text prompt, acting as an image editing tool.
Pick the cheapest variant that meets your quality bar. Most teams start on the fast variant and graduate to pro for production.
