Submit your prompt and parameters to the model's documented endpoint.
Poll the task or set a webhook, then download the completed output.
GPT-4o Image integrates visual creation natively into GPT-4o, combining reasoning with generation. Through RunAPI, it shares the same API access and billing as all OpenAI models.
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.
GPT-4o Image generates images natively within the GPT-4o conversation, using conversational context to inform the image. GPT Image is a standalone generation endpoint.
The model uses the full conversation history to understand what you want — you can iteratively refine images by describing changes in natural language.
GPT-4o Image handles many distinct objects in a single scene while maintaining compositional coherence and object identity.
Yes — describe the changes in the conversation and the model modifies the existing image while preserving the rest of the scene.
Yes — the conversational interface makes it natural to iterate: generate, review, describe adjustments, and regenerate without rewriting the full prompt.
Pick the cheapest variant that meets your quality bar. Most teams start on the fast variant and graduate to pro for production.
