description OpenAI Image Generation API Overview

This API allows developers to programmatically create high-quality images from text prompts (and later, from other images). It is vital for applications needing dynamic visual assets, such as game content generation, marketing mockups, or unique profile pictures. Its integration with the main OpenAI platform makes it straightforward to use within larger AI workflows.

help OpenAI Image Generation API FAQ

Which OpenAI model and endpoint should I use for new image generation work?

OpenAI currently lists GPT Image 2 as its state-of-the-art image generation and editing model. The model supports the Images API generation and edit endpoints and can also be used through the Responses API. [GPT Image 2 model documentation](https://developers.openai.com/api/docs/models/gpt-image-2)

Can the OpenAI Image Generation API edit an existing reference image?

Yes, image input and output are supported, so an application can send a reference image with instructions for an edit or variation. The edit endpoint is separate from ordinary text-only generation, and the application should preserve the original file if it needs a reversible workflow.

Does an OpenAI API image call include image hosting for my users?

The API generates image output, but a production app still needs to store, moderate, and serve the resulting asset from its own storage or delivery system. Treat the returned image as output data, not as a permanent public media library.

Can the OpenAI Image Generation API create readable text for a marketing mockup?

It can create images containing signs, labels, and other designed text, which makes it useful for mockups and interface concepts. Text-heavy artwork still needs human or automated review because a visually strong image can contain lettering errors.
