His verdict: "the best model I've ever used. Period" — a massive, non-incremental improvement, with demos in his thread. Every's accompanying Vibe Check offers a more balanced take: excellent writing, software operation, and visual design, but Anthropic's Fable still shows better product-building instincts.
