ChatGPT Images 2.6 Explained: GIFs, References, and Faster API Models

What OpenAI announced

Images, upgraded—introducing ChatGPT Images 2.6. Now with GIFs and reference images. Plus, two new models are coming to the API with 50% faster image generation.

ChatGPT Images 2.6 is OpenAI's next image release, framed as an upgrade rather than a brand-new product line. The public announcement pairs two changes you can use inside the ChatGPT image experience—GIFs and reference images—with a separate API track.

The API side names two models, Flare and Sunburst, also referred to as GPT-Image-2.6 Flare and GPT-Image-2.6 Sunburst. OpenAI says those models are coming to the API and will generate images 50% faster. No architecture diagram, parameter count, or training description shipped with the announcement.

GIFs and reference images

GIFs are the clearest new output type. Instead of a single still, ChatGPT Images 2.6 can produce short animated images. That fits loops, simple motion, and reactions where a still frame loses the point.

Reference images are the other half of the upgrade. You can supply an image the model should work from, which is the usual path for keeping a subject, style, or layout consistent across new generations. OpenAI has not published how many references you can attach, which formats are accepted, or how strongly a reference is followed.

• Motion

  GIF output is the new animated format called out by name.

• Guidance

  Reference images let a generation start from a picture you provide.

• Still images

  The release is described as an upgrade to Images, so still generation remains the base experience.

Flare and Sunburst on the API

Flare and Sunburst are the two new image models headed to the API. The only performance figure OpenAI attached is speed: image generation 50% faster. Nothing in the announcement compares them to each other, so you cannot yet tell which one is meant for quality, cost, or a specific resolution.

Developers should treat both names as upcoming API models under the GPT-Image-2.6 line. Open weights are not part of the announcement, and no rate limits, image sizes, or prices were included. Until those details land, the 50% speed claim is the only spec you can plan around.

What you still cannot confirm

There is no dedicated page for ChatGPT Images 2.6 yet. OpenAI's official site is openai.com, which is the place to watch for docs, model names in the API, and any rollout notes. Access steps, plan limits, and regional availability were not part of the announcement.

Open questions sit next to the features. GIF length and frame rate, how reference images are weighted, how Flare differs from Sunburst, and whether the 50% speedup is versus the previous image API are all unpublished. Treat the release as real and narrow: animated output, reference images, and two faster API models on the way.
