Someone more knowledgeable on how these LLMs are trained and fine-tuned can weigh in, but it absolutely does matter. Some models are much more "willing" to use tools (and more adept at discerning when to use them) than others.
I can't comment on why you're having this issue specifically, unfortunately.
yeah, this was not about eagerness to use a tool. It specifically listed available tools and functions and insisted it can not access this playwright related ones.
As I readily admit in my parent comment, I'm not an expert on the tool-calling mechanics. But from other threads, my understanding is it can be a manifestation of the same issue. I know that's not really helpful to you, just wanted to call out that switching models can alter this behavior.
