ChatGPT Images 2.5

Overview

ChatGPT Images 2.5 is OpenAI‘s image generation model powering ChatGPT’s image surfaces as of October 1, 2026 — natively integrated into the ChatGPT product rather than exposed as a standalone API-first endpoint. OpenAI claims more natural lighting, richer textures, more reliable edit-instruction following, and reduced latency vs the prior image-generation stack. The model shipped alongside the Try-On commerce feature and the Favorites product library.

Timeline

• 2026-10-03-AI-Digest — ChatGPT Images 2.5 launches on October 1, 2026 as the image model powering the new global Try-On feature (upload selfie or full-body photo → visualize clothing / accessories) and the Favorites product library. OpenAI claims more natural lighting, richer textures, more reliable edit-instruction following, and reduced latency. Corpus framing: the model is incremental to the existing ChatGPT commerce stack (Checkout, shopping tabs, Walmart partnership) — Try-On annexes Pinterest Lens / Google Lens visual-intent shopping territory, not Amazon’s logistics moat.
