GPT-5.4 dropped in Perplexity, anyone tried it yet?

I messed with GPT-5.4 for like 20 minutes during lunch and my first reaction was, ok this thing is weirdly confident...but also way better than 5.3

I threw it a messy question about California insurance rules because my cousin is dealing with a claim and Sonnet 4.6 usually does fine there. GPT-5.4 felt faster at getting to an answer, but also more willing to say something like it had the whole situation figured out. Sonnet still feels a little better when I want nuance and less chest-thumping.

For normal search stuff, GPT-5.4 might be the move. For anything where I really care about wording, citations, edge cases, I still kind of trust Sonnet more. Maybe that's just me being used to Claude style answers. But 5.4's writing style and overall language has seemed to take a massive improvement.
