Introducing Claude Sonnet 5.5, the second model in the Claude 5.5 family.
It’s a clear upgrade over Sonnet 5, runs more than 30% faster, and costs up to 30% less for most work.

It's not so much beneath Opus that's for sure.

SONNET 5.5 IS CRAZY.
I asked it to draw "Goldilocks and the Three Bears" in JavaScript.
- 4 minutes.
- Character voices, music and sound effects all included.
- Every frame drawn in code.
- Just as good as Opus but faster & cheaper.

1) what: sonnet 5.5 beating half the lineup at a third of the price
2) how: opus 5.5 did the homework, sonnet copied it
they are distilling mythos and doing the alpha go zero loop of high quality synth data -- this is the hard curve part of the foom loop
I genuinely can only imagine what fable 5.5/6 is going to be. This is clearly all a build up to that. It may literally be revolutionary.
When I see Sonnet’s xhigh outperforming Max and Grok 4.7’s high outperforming xhigh, it reminds me of people who overthink so much that they never take action and end up failing
I'm still using Fable to orchestrate Opus agents. Should I just get Opus to do that instead with Sonnet.
I'm so confused.
