This is what Claude Opus says about itself:

It depends heavily on definitions. I'd lean toward "no" — I lack persistent learning, can't update from experience, and still fail at certain reasoning tasks that humans handle easily. I'm more accurately described as a very broad, capable AI system rather than a genuinely general one.

@JeromeHPowell And this is what Sonnet 4.5 says 😂 :

I notice you're asking about "Claude Opus 4.5" - there isn't a model with that exact name. The Claude 4 family includes Claude Opus 4.1 and 4, plus Claude Sonnet 4.5 and 4. You might be thinking of either Opus 4.1 or Sonnet 4.5?
