GPT-4.5 is a BIG model with "big model smell." That means it's Smart, Wise, and Creative in ways that are totally different from other models.

Real ones remember Claude 3 Opus, and know how in many ways it was a subjectively smarter model than Claude 3.5 Sonnet despite the new Sonnet being generally more useful in practice. It's a similar energy with GPT-4.5. For both cost and utility, many will still prefer Claude for most use cases.

The fact is, we don't just want language models to code. Perhaps the highest leverage thing to do is to step back and find your way through the idea maze. That's where you want big models. 

While GPT-4.5 is hands down the biggest model available, it's not the only one with these characteristics. I get similar vibes from Claude 3.7 Sonnet (thinking or not) and still often prefer Claude. It's shockingly insightful, creative, and delightful.

I'm trying to use GPT-4.5 for more of my chats over the coming days to get a feel for it.
