Flux Kontext is an editing model, but the set of things it can do is incredibly limited. The style of prompting is very bare bones. Qwen (Alibaba) and SeedEdit (ByteDance) are a little better, but they themselves are nowhere near as smart as Gemini 2.5 Flash or gpt-image-1.
Gemini 2.5 Flash and gpt-image-1 are in a class of their own. Very powerful instructive image editing with the ability to understand multiple reference images.

Both gpt-image-1 and Gemini 2.5 Flash feel like "Comfy UI in a prompt", but they're still nascent capabilities that get a lot wrong.
When we get a gpt-image-1 with Midjourney aesthetics, better adherence and latency, then we'll have our "GPT 4" moment. It's coming, but we're not there yet.
They need to learn more image editing tricks.
My test is going to https://unsplash.com/s/photos/random and pick two random images, send them both and "integrate the subject from the second image into the first image" as the prompt. I think Gemini 2.5 is doing far better than ChatGPT (admittedly ChatGPT was the trailblazer on this path). FluxKontext seems unable to do that at all. Not sure if I were using it wrong, but it always only considers one image at a time for me.
