Opus 5.5 tops RoastBench
Made a little benchmark called RoastBench - it compares frontier models on their roast jokes. The models roast 10 personalities from comedy central roasts I enjoyed, and I manually rank their jokes. I also mark the ones that made me laugh. LLMs are way worse than top humans.

RoastBench results for Fable 5.1 and GPT-6. They're tied on the main set, but fable does a lot better on the second set. Neither felt like a major step up though.

if you've been holding out on fable due to price or zdr you really should try fable 5.1
We’re introducing Claude Fable 5.1 and Claude Mythos 5.1. They're the world’s most advanced models for coding and knowledge work.

Added Opus 5, GPT 5.6 Sol and Kimi K3 to RoastBench. Opus 5 narrowly edges out Fable at the top
