Stillwet just got open sourced - AI models literally painting by coding against a simulated oil canvas instead of using image gens

How it works:
→ Models program brushes, wet paint physics, drying times, layered glazes - all through code
→ 75 paintings from Claude Opus 5.5, GPT-6.1 Sol, Gemini 3.8 Flash
→ Most replicate Caspar David Friedrich's style using only written research (no image training)
→ Wild detail: When asked to paint freely, Claude Opus chose a jug with lemons 6/6 times

This is a different approach to AI art - models as painters, not prompters. Code becomes the medium.

Repo is live for anyone who wants to experiment with AI painting mechanics.
