For coding I've found ChatGPT4 a bit better than Claude 3 Opus because it tends to understand my intentions more and I trust it to make better suggestions for code changes.

I think Claude has better writing style, and it's refreshing not having to fight with the thing to get it to give me full code snippets. I also hate how difficult it is to get the arrow keys to scroll up or down on chatgpt.

It's interesting that we all have different experiences.

I've found Claude 3 massively better than ChatGPT4 for my use cases.

ChatGPT4 will just get the question entirely wrong the majority of time on high levels of complexity.

For example, here's this 1k lines of code. Find this bug, and fix.

ChatGPT4 totally gets it wrong, Claude 3 gets it right, or at the very least finds the area to get it right.

This is repeatable over and over all day.

Edit: The funniest part of my workflow is when one LLM gets an idea wrong, I then put it to the other LLM.

It's a great way to get unstuck. Both LLMs get stuck on certain things, but they are usually different things.

It might be language or task dependent. I'm writing C++, and Claude is more likely to suggest things which simply won't compile. It feels like Claude 3's knowledge of C++ is a bit lacking comparatively.

For me GPT4 seems to suggest more generic unittests in python. They're much more "Put tests here", or "path.to.dependency".

Claude3 opus (and often Sonnet) actually fills in the full dependency paths, actually makes tests, and just overall seems to "know what I want from it".

This tends to be my experience, but mainly when it comes to areas that neither model know about. Claude 3 Opus will happily make something up, but ChatGPT4 will point out where it's lacking.
