ChatGPT Images 2.5 Review: What's New and Is It Worth Using in 2026

 

OpenAI released ChatGPT Images 2.5 on September 8, 2026, roughly five months after the previous major version, Images 2.0. This review breaks down what actually changed, who benefits most, and whether it's worth adopting.

What OpenAI says is new

According to OpenAI, Images 2.5 brings sharper details, richer textures, and more natural lighting compared to the previous version. The company also states that generation latency has been reduced by up to 50% relative to Images 2.0, and that the model is more reliable at preserving subjects from reference photos across new settings, styles, and compositions.

The consistency improvement matters more than it sounds

One of the most practical improvements in this release addresses a common frustration with AI image editing: consistency across multiple rounds of edits. In earlier versions, running an image through several consecutive edits often caused unrelated details to drift — a background color shifting, a face subtly changing, or an earlier edit silently reverting. Images 2.5 is designed to change only the specific element requested in each edit while keeping the rest of the image stable, even across many editing turns. For anyone doing iterative design work, this is arguably the most valuable change in the release, more so than the speed improvement.

New creation and editing tools

Two new interaction tools were introduced alongside the model itself:

  • Sketch, which allows users to draw a rough reference directly inside ChatGPT and use that drawing to guide the generated image.
  • Comment-based editing, which allows users to point to a specific part of an image and describe a targeted change, rather than rewriting an entire prompt to fix one detail.

Availability

ChatGPT Images 2.5 is available across ChatGPT, ChatGPT Work, and Codex, on every subscription tier including the free tier, across desktop, mobile, and web.

For developers: two new API models

Developers building on the API have access to two distinct models:

  • GPT-Image-2.5 Flare, positioned as the fast, default option suited to most everyday generation needs.
  • GPT-Image-2.5 Sunburst, designed for premium workflows requiring tighter editing control.

Both models are billed at the same per-token rate as the previous generation model, meaning there is no price increase associated with the quality improvements.

Provenance and content transparency

OpenAI describes a layered provenance approach for generated images, referencing both C2PA metadata standards and SynthID-style invisible watermarking, intended to help verify whether an image was AI-generated.

Final verdict

ChatGPT Images 2.5 is best understood as a refinement release rather than a full reinvention — and that's reflected in the naming. The improvements to multi-turn editing consistency and reference photo fidelity are the parts most likely to matter for real-world use, particularly for anyone doing repeated iterative design work such as product concepts, social media assets, or presentation graphics.

AI for Google Sheets in 2026: What's Actually Worth Using

Image
 Google Sheets has always been powerful because of its flexibility, but that flexibility has traditionally come at a cost: manual data entry, formula debugging, and repetitive reporting eat up hours every week. Over the past year, AI tools built directly into and around Sheets have matured enough to meaningfully change that. This guide covers what's actually useful right now. Why this shift matters A spreadsheet is only as useful as the time it takes to maintain it. Most of the friction in day-to-day spreadsheet work isn't complex analysis — it's repetitive, mechanical tasks: cleaning messy data, writing the same type of formula repeatedly, and rebuilding reports that could have been templated. This is precisely the category of work AI tools handle well. The main categories worth knowing 1.
