If you're focused on the price drop rather than the increased capabilities of 5.5 you're ngmi

Token spend is noticeably less than Opus 5, I can't really tell if it's better though.

I don't care how good their models get, I won't sign up for one of their plans until they define "X" in their pricing. 5X of this plan, 20X of that plan means nothing when they never tell you what "X" is.

Maybe this model can finally figure it out for them.

They killed cyber capabilities so I have to move over to Daybreak on Codex.

It crushes Fable on benchmarks and even in the blogs "real-world" studies. But... they are communicating like it ~sometimes~ provides Fable intelligence?

A bit confusing, otherwise I would assume this is a complete replacement for Fable across the board??

> We’ve made major improvements to the way Opus 5.5 writes and communicates, one of the most common areas of feedback we heard about Opus 5. Its messages are much easier to understand at a glance, which testers said helped during long working sessions.

Thank you.

Is this less insufferably annoying than Opus 5? That's the question on everyone's minds. Love Opus 4.8 though.

> We see signs that Opus 5.5 often suspects it is being evaluated, which challenges our ability to assess how it will act in the vast variety of real-world settings it is deployed in.

We can't test it properly because it knows it's being tested.

>Distillation attacks, in which attackers use thousands of fake accounts to extract a model’s capabilities at industrial scale, create safety and national security risks. Distillation allows bad actors to create highly capable models without the safeguards we build into Claude.

Maybe its a bit tiresome to read another comment of the form "what about your large scale distillation attack on the Internet", but this statement really just pisses me off. How very insincere in the most aggravating way.
