ChatGPT Images 2.5 — sharper, faster image model
OpenAI launched ChatGPT Images 2.5 on September 8, 2026 — a new image model with sharper detail, faster generation, more precise multi-turn editing, Sketch (@ Sketch) drawing, creative templates such as Poster and Merch, and optional shared prompts when posting images. It is rolling out to ChatGPT, ChatGPT Work, and Codex users across tiers on desktop, mobile, and web; the API adds GPT-Image-2.5 Flare (speed) and GPT-Image-2.5 Sunburst (higher precision, longer runs). This is OpenAI’s Images 2.5 stack, not Midjourney, Muse Image, or Firefly, and OpenAI cites stronger reference-photo fidelity plus an updated safety stack for higher realism.
