for the past few weeks, I’ve been exploring painting with Fable 5.2 in code. one of the most common critiques I heard about Opus 5.5’s paintings was that it was only emulating real art. I thought that was fair, so i’ve been asking Fable 5.2 to develop personas—artists with some sort of a back story and a consistent style roughly identifiable in time
not knowing what to expect, i’ve watched this project evolve in directions i never predicted. I give comments or steers, and Claude updates or revises the engines that power the brushes and paint. where paintings come up i like or find intriguing, i ask it to go deeper. these are some favorites.
each of these is a python program, some one to two thousand lines of code, that places every stroke through a simulated paint engine with different bristles. most take a few thousand strokes, but i’ve pushed much higher with varying results. Claude does not use an image model, nor render or trace in advance

I’ve been impressed with its consistency. these are the paintings of a persona Fable 5.2 developed, "Dermot Hale," who “paints weather in thick oil with a knife and big brushes, usually in unscenic places like a retail park or a drive-in, at the moment just before it changes. His stated reason: ‘it is large, it is on time, and nobody is in charge of it.’

it likes aerial views. I was particularly taken with a persona claude called “The Tidewright”

I asked Fable 5.2 to create a painting as indistinguishable as possible from a photograph. this is roughly 700,000 simulated brush strokes
