Mona Lisa
The same painting, prompt and effort, compared across AI models.
On this page
I thought it would be fun to make AI models paint something familiar to everyone, yet challenging enough so there is room to grow for the future. This is where I gather their versions of the Mona Lisa for comparison.
The benchmark
Every model gets the same prompt through Opper, with
reasoning_effort: "high":
Paint the Mona Lisa as an SVG. Use viewBox=“0 0 800 1200”.
Each painting is the model’s first result, without edits or retries. The SVG is rendered as an image for display here. New models get a short post with their own painting, and their result is added to this page.
The captions show the recorded time, output tokens and cost for each run. Gemini 4 Carbon was run on November 11, 2026; the other models were run on November 10.

I think the results are quite interesting, and while most models get the high level right, there is plenty of room for improvement.
