this JUST became the #1 AI model...

I've been building with Claude Fable 5.1 since launch day, and this is what came out: Blood Grid, a fully voiced Blood Bowl-style fantasy football game with its own AI engine, a headless simulator, and a Bradley-Terry balance bench; a Matrix-style bullet-time subway shooter; an isometric Tarkov-style extraction game that plays itself; and The Gilded Mansion, an Among Us-style social deduction game where the players are LLMs. No bugs, no derping out, and it kept warning me about the knock-on effects of my own rule changes before I could break the game. The twist: almost all of it was built on LOW and MEDIUM effort. If you think Fable 5.1 is overrated, your effort slider might just be set too high.
