ChatGPT Images 2.5: What’s New, How to Use Sketch, and the Hidden Snake Game

ChatGPT Images 2.5 was released on September 8, 2026, delivering roughly 50% faster image generation, precise local in-painting, persistent character consistency, and a new Sketch tool. Additionally, an unannounced easter egg allows users on select clients to tap the rendering loading animation to play a retro Snake minigame.

Key Takeaways

• OpenAI released ChatGPT Images 2.5 on September 8, 2026 with 50% faster rendering times.
• New features include sharper details, precise local in-painting, and an interactive Sketch composition tool.
• Users discovered a hidden easter egg: tapping the loading screen during generation starts a playable Snake game.
• Supports iterative prompt refinement (e.g. keeping faces while modifying backgrounds or weather).
• Subject consistency and text generation are significantly improved, though background drift can still occur.

On September 8, 2026, OpenAI rolled out ChatGPT Images 2.5. Official release notes say it is sharper, better at precise edits, and faster. Tom’s Guide’s hands-on report says generations can be about 50% faster than Images 2.0, with more reliable instruction-following and better subject consistency when you keep editing the same photo.

That is the useful story. The shareable story is what some users found while waiting: tap the loading animation and a Snake game appears.

What Images 2.5 actually improves

From OpenAI and early tests:

• Cleaner detail and lighting
• More precise local edits (“change only the background,” “keep the same face”)
• Faster image generation (up to ~50% faster turnaround)
• Better handling of iterative edits instead of starting over from scratch
• A Sketch tool, so you can draw a rough layout and have ChatGPT use it as a composition reference

People are already using it for product mockups, poster layouts, photo cleanups, and frame-by-frame GIFs. One creator generated 12 stills in Images 2.5 and stitched them into an animation without a separate video model. Consistency is improved, not perfect. Backgrounds can still drift.

How to use it

1. Open ChatGPT on web or in the app.

2. Start a new chat and attach a photo, or ask it to generate one.

3. For edits, be specific: *“Keep my face and the red jacket. Replace the street with a rainy Tokyo alley at night.”*

4. If Sketch is available in your client, draw the composition first, then describe materials and lighting.

5. Ask for one change at a time. Big combined prompts still confuse image models.

Free users may see tighter daily limits. Paid plans get more image attempts. Exact caps change with demand.

The Snake easter egg

Several users say that after the Images 2.5 rollout, tapping the image-loading or animation screen starts a tiny playable Snake game while the picture renders. It is not listed in OpenAI’s official Images 2.5 notes. Treat it as a user-reported easter egg that is rolling out unevenly.

If you want to look for it:

1. Generate an image in ChatGPT.

2. While it is rendering, tap the loading or animation area.

3. If nothing happens, you probably do not have that build yet.

*Note: Do not install a third-party “ChatGPT Snake” app. The report is about a screen inside ChatGPT itself.*

Limitations

• Image quality still depends on the prompt and the reference photo.
• Text inside images can still break occasionally.
• Hands, logos, and tiny type remain relative weak spots.
• The easter egg may vanish in a later update.
• Do not upload sensitive photos you would not want stored in an AI product.
