It was quite insufferable: https://blog.kronis.dev/blog/ai-slop-is-a-self-inflicted-tra...

Long story short, I ended up looking at other providers and models like Kimi K3 and GLM 5.3 and eventually just stuck with OpenAI (more limits, despite smaller context), none of them have such pronounced issues with the tone and writing like Claude does - seems like they were working on it with 5.1 but I'd almost classify it as a form of model collapse.

I wince whenever I catch Claudisms on websites and elsewhere. Same as with that pulsating circle that indicates nothing.
