Ask HN: What is your experience with Claude 3.5?

#1
Hey there,

I've been using Claude 3.5 for a couple of days now and I must say this is insane. It is so much better than OpenAI at coding.

I am a Data / Backend guy and I don't have that much experience with React / JS browser frameworks. Claude is incredibly good in writing good code fast. I've been using ChartJS with some pretty esoteric plugins and Claude nails every question first try.

What is your experience with it, do you feel the same?

I've been programming for 10y+ but now I completely rely on AI for coding (using the Cursor IDE). It's made me easily 4-10x faster.

Tbh it's making a lot of mistakes when writing with the latest Next.js versions of the new modules.

Maybe because of the knowledge cutoff? Idk

(Or maybe it's a signal to stop coding in JavaScript...)

If you haven't yet, pay for the upgrade to use Projects. I've uploaded entire codebases, then opened different conversations about that codebase, generating very useful artifacts.

Also, Claude artifacts can display MermaidJS. You can give it a whole codebase and ask something like "generate a sequence diagram of this process" and it does a remarkable job of doing so, displaying results in realtime.

Pretty positive, much better than my experience with OpenAI's models. The killer feature for me is their prompt generator[1], which you can use to create system prompts or improve user prompts. As I said in another thread, the generator is tuned to generate prompts better suitable for Claude, which improves responses.

You can see examples of the prompts it generates in the repository linked below, including a customized version of their prompt generator[2]. This feature significantly improved my experience with LLMs in general, both Claude and local ones, and I now use Claude 3.5 Sonnet for pretty much all my coding, mostly in Go and, lately, Rust.

I mostly use it to improve existing code or to get started, not to generate entire code bases, so I can't say much about that.

I found it lacking in shell scripting though. Nine out of ten times I need to fix the shell script it generates, to a point where I just gave up trying and went back to writing them from scratch.

Can't wait to see how much better Claude 3.5 Opus is, though.
