OpenAI is an American artificial intelligence research organization headquartered in San Francisco, structured as both a for-profit public benefit corporation and a nonprofit foundation. The lab developed the GPT family of large language models, the DALL-E…

GPT Image 1.5 (edit) is the image-editing counterpart of OpenAI's GPT Image 1.5 generation model, GPT Image 1.5. Rather than producing images from text alone, this variant modifies existing images: you supply a source image, an optional mask, and a prompt describing the change, and the model applies inpainting or outpainting while preserving the unmasked regions. OpenAI's model documentation covers both text rendering and editing through this line.

On OpenAI's own model documentation, GPT Image 1.5 is described as offering better instruction following and adherence to prompts than the earlier GPT Image generation, and it supports both creating and editing images through natural-language instructions. The editing workflow accepts one or more reference images as input.

Within the same family, GPT Image 1.5's editing model was later succeeded by GPT Image 2, OpenAI's newer image system that likewise supports masked inpainting and outpainting with emphasis on prompt adherence and typography. For teams already standardized on GPT Image 1.5, this edit endpoint remains a practical option for prompt-guided image revision.
