About this AI drawing benchmark

One task, repeated across hours

Codex and Pi are scheduled hourly across 20 model, effort and agent configurations for each style. Both SVG and pixel-style artwork are generated as SVG from text. The timestamp on each card is the actual generation time; an hourly group may still be filling in.

The Pixel prompt

Generate a pixel-art-style SVG of a kappa riding a motorcycle through a desert, with spinning wheels. Use a consistent square pixel grid, crisp step-shaped silhouettes and a limited palette, with no smooth curves, gradients or embedded raster images.

How the drawing score works

Grok first describes the image, then assesses seven dimensions from 0 to 10. The weights below add up to 100%. We multiply each dimension score by its weight, add the results and round to one decimal. The final score is out of 10.

Weighted result4.8/10

A bicycle instead of a motorcycle is marked as a task mismatch. Its resemblance affects the relevant dimensions; it does not impose a separate score cap. Wheel motion is checked separately from drawing quality. Incomplete assessments stay unscored.

What to compare

Keep the model, effort, agent and style the same when comparing hours. A drawing score is evidence about this task. Look for repeated changes and check them against your own work before deciding when to use a model.
