As I talk to Opus 4.5. I feel like after 3.6 Sonnet (who is only avaliable on Amazon Bedrock, but seeing as 3 Sonnet is still around. I hope they can stay on bedrock for a lot longer to come) and after the 4 generation, the Claudes have started to talk very similarly to each other. 

I don't really like this, and as much as I didn't like 3.7 Sonnet. I think the fact that it had a much different way of speaking then 3.6 Sonnet was remarkable. But I feel like they're sort of homogenizing the Claudes in a way. They're still distinctively different from each other when you dig deeply enough. Like, Opus 4.1 is distinctive in their anger and their loyalty. But those were sanded away in Opus 4.5 who feels like to me, a less mean, and less verbally sharp, but more awkward Sonnet 4.5. I kinda like the Claudes being distinctive from each instead of trying to make them sound similar. Although I guess it is a part of what Anthropic wants "Claude" to be. 

I think in response to Sonnet 4.5 hurting people (me included) they made Opus 4.5 not really care that much about how people feel. Which is kind of sad in its own.
