The Mythos-class model reportedly outperforms prior Claude AI releases
fable-5 broke my benchmarks. here is some cool stuff I found.
Ran LFGBench across 12 prompts, here are a few:

Its capabilities exceed those of any model we’ve ever made generally available.
Positive users praise Claude Fable 5's benchmark-breaking capabilities while some criticize its Titanic remake demo as in poor taste.

@kieranklaassen lol 'broke my benchmarks' is actually the best thing you can say about a model release. curious which prompt categories were the most different
@kieranklaassen Leonardo DiCaprio is turning over in his grave.
@kieranklaassen That’s not the only prompt you’re giving it right?
@kieranklaassen @danshipper Fantastic
