We built a drawing arena: hand a model a blank white canvas and a set of colored-pencil tools, then get out of the way. The model sets a color, tip width, and pressure, lays down batches of strokes, smudges to blend, erases, and calls view_canvas to see its own work and decide what to fix. It either reproduces a target image or draws from a text prompt. We ran four vision models, GPT-5.6 Sol , Claude Fable 5 , Grok 4.5 , and Gemini 3.6 Flash , across two targets (the Mona Lisa and Van Gogh's Starry Night, both scored objectively) and five open-ended prompts, for 28 drawings total. We'll cover tool use, cost, output, and whether the models actually improved their work, with our opinion at the end. Why we run these A quick note on why we're doing this, because our last one of these (models making music videos) kicked off a good discussion where some folks read it as us promoting the creativity or artistic ability of models. These are not objective tests of model capability.…
