Is it possible to generate multiple images at one with chatgpt image 2.0?

Hi @neat lake. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

Simultaneous / multi-image generation is supported in the Image API, but the behavior depends on the model and endpoint:

With the Images API (/v1/images/generations), you can set the n parameter to generate multiple images in a single request. This is supported for models like dall-e-2 and gpt-image-1.5 (the “GPT image” models). [Generate images; Images create]
For DALL·E 3, n is restricted to 1 for reliability; to get more than one image you must make multiple calls in parallel. [DALL·E 3 API]

The knowledge sources you provided do not mention a model literally named “ChatGPT Image 2.0”, so I can’t say anything specific about that name. They only describe “GPT image models” such as gpt-image-1 and gpt-image-1.5, which do support multiple images via n on the Images API. [Images create; Generate images]

If you’re instead using the image_generation tool in the Responses API, the docs do not show an `n` parameter there; the tool returns (effectively) one image per tool call, and multiple images would require multiple tool calls. [Tools image generation; Forum answer]
