OpenAI has released ChatGPT Images 2.5, an update to its image generation models that enhances instruction-following capabilities across multiple turns and increases response speed. The new version is also better at preserving subjects from reference photos provided by users.

  • Two new API model IDs are available: gpt-image-2.5-sunburst for editing precision and gpt-image-2.5-flare for fast, high-quality everyday generation.
  • The update supports passing one or more reference images to guide the output.
  • OpenAI reports its models have generated over 3 billion images across ChatGPT Images and the API.

This release allows users to generate images with greater fidelity to source material and complex multi-turn prompts.
