GPT-Image-2.5 Flare and Sunburst Released With ChatGPT Images 2.5
- OpenAI released ChatGPT Images 2.5 on 8 September 2026, five months after ChatGPT Images 2, rolling it out "today to ChatGPT, ChatGPT Work, and Codex users across all tiers on desktop, mobile, and web"[1][4][6]
- Two new API models shipped the same day for the Image API and the Responses API image generation tool: GPT-Image-2.5 Flare and GPT-Image-2.5 Sunburst[2][3][5]
- ChatGPT also gains Sketch, which lets users draw a reference right in the chat by typing "@Sketch", templates for formats such as posters and merch, and a way to share the prompt behind an image[4][6]
- The release came five days after OpenAI launched GPT-6 Astra[6]
Notable features
- OpenAI says Images 2.5 produces "more natural lighting and richer textures", keeps the subjects of reference photos better, follows editing instructions more reliably over several turns, and cuts generation latency by up to 50% compared with Images 2.0[6]
- Flare is the default, "our fastest model for high-quality, everyday image generation", giving higher-quality images than GPT-Image-2 at 50% lower latency; Sunburst is "our most capable model for image generation and editing", for work where editing precision matters most, at the cost of longer generation times[2][3][4][6]
- Both take text and image input, output images, and add new xhigh and max quality settings alongside low, medium, high and auto[2][5]
- API prices match GPT Image 2: $5 per million text input tokens ($1.25 cached), $8 per million image input tokens ($2 cached) and $30 per million image output tokens[2][5]

Suggest a correction
Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
