GenAI Image Editing Showdown (via) Useful collection of examples by Shaun Pedicini who tested Seedream 4, Gemini 2.5 Flash, Qwen-Image-Edit, FLUX.1 Kontext [dev], FLUX.1 Kontext [max], OmniGen2, and OpenAI gpt-image-1 across 12 image editing prompts.

The tasks are very neatly selected, for example:

Remove all the brown pieces of candy from the glass bowl

Qwen-Image-Edit (a model that can be self-hosted) was the only one to successfully manage that!

This kind of collection is really useful for building up an intuition as to how well image editing models work, and which ones are worth trying for which categories of task.

Shaun has a similar page for text-to-image models which are not fed an initial image to modify, with further challenging prompts like:

Two Prussian soldiers wearing spiked pith helmets are facing each other and playing a game of ring toss by attempting to toss metal rings over the spike on the other soldier's helmet.
