I use gpt image 2 very heavily for my current project (ai UI design tool). The biggest improvement I'm seeing with this is in speed. I've generated around 50k images with gpt-image-2 via api, the the average latency has held at around 104s.

It's wild how much of a difference this is - images are coming in at around 35-40s. Very noticable, and makes a difference when you're iterating quickly: https://jjcm.org/gpt-image-2.5-speed.mp4

Some UI tests with it:

Warcraft 3 style agentic dev interface: https://image.non.io/cd9ea5cd-8ed7-44e0-ad3f-480ff0e51875.we...

Overall it used the reference images I gave it a bit better than gpt-image-2. I noticed 2 had issues getting the blue button just right. 2.5 nailed it.

A "John Politics" meme site: https://image.non.io/d2922164-fa96-4d07-a141-2febadb02939.we...

Did very well modifying the pose while keeping the appearance of Glenn Powell. gpt-image-2 had a lot of the "fried" look for some of his skin in prior designs I did for johnpolitics.com

A cyberpunk inspired ramen website: https://image.non.io/8d5d8f10-0f0f-4d91-b5ea-33af7538b150.we...

Dark mode sites surfaced the fried look quite a bit in prior models, but this definitely looks better on that front. One thing that looks perhaps worse though is the microglyphs - note the teal lines to the bottom right of the ramen, they're kinda blurry / not straight.

Overall fixed some of the main issues / gripes I had with gpt-image-2

		The WC3 one is fun. Definitely feels close to what I remember.

		>Warcraft 3 style agentic dev interface I can forgive the randumb placement of chains but not that sovlless icon of a person from the wow era. wc3 era UI would've used a character portrait.

		Love the John Politics page, utterly slick completely bland and phoney. Assume it’s a meme i missed, love it.

I'm confused. Isn't diffui using its own model?

It's both. I have several models loaded into diffui. Which one each prompt uses is determined based on user preference over time. Whichever image is currently at the top of any image node stack marks a win for the model that generated it, I assign each model an ELO score based on that, and I bias the chance each model is selected based on their ELO score. Right now gpt-image-2 is better than my own model, and it services around ~96% of the requests in diffui.

I'll also be adding in microsoft's mai-image-2.6 soon, but I need to update my SOC2 to add MS as a provider before I turn that on for other users. The full list of models in rotation is here: https://image.non.io/d53a9760-8b74-4386-b032-d59da2cd5319.we...

Oh, you're the dev of diffui? It's completely off-topic, but I've notice that RMB -> Download image will download an .png but it's actually a .webp and it can cause issues (e.g. file explorer doesn't show thumbnail correctly).

		Indeed I am! Also nice catch - should have a fix up in the next hour. Hit me up with any other reqs - j@diffui.ai Edit: confirmed that the download should be fixed now - should be properly a png now.
