Opus 5.5 paints pixel-by-pixel in pure Python code, no image model

Developer jkeatn has been asking models to paint for months — with no image model or art software. Every image is a Python program drawing pixel by pixel: 7,500 lines of code using standard libraries to emulate different painters' brush styles. The agents use no reference pictures, only what they know about each painter; Opus 5.5 is reportedly very skilled at style emulation.
