Source: https://x.com/jkeatn/status/2102441348075057539 ## Why it matters Launch-day demonstration (~840k views) that Opus 5.5 can emulate painting styles through ~7,500 lines of code, with no image model. ## Summary Posted on Opus 5.5's launch day, quoting @claudeai's announcement: Jake Eaton says he has been "asking our models to paint" for months; every image in the post is a Python program generated pixel by pixel, about 7,500 lines of code using standard libraries to emulate brush styles, with no image model, no art software and no reference pictures. ~840k views on Oct 29 (fxtwitter).
