for the past few months i’ve been asking our models to paint. opus 5.5 is very skilled at emulating different styles
every image here is a python program generated pixel by pixel. there is no image model, and no off-the-shelf art software. instead, it’s about 7,500 lines of code using standard libraries to emulate different brush styles. the agents don’t use any pictures as reference, instead working only from what they know about each painter
