Opus 5.5 was a good model in my early tests, first non-Fable/Astra model to feel like a Fable-class model, but still hasn't fully solved the dense language issue of the recent Claudes. Its version of the same shader (broken towers are a nice touch): https://twigl.app/?ol=true&ss=-P291BpUn5… https://x.com/emollick/status/2102441628…

The drowned neo-gothic tower twigl shader created by Fable 5.1 with the same prompt. (compare to Fable 5 in the quoted tweet, and other models before that) https://x.com/emollick/status/2094983856424358023/video/1
