There is a big difference between vibe coding and using an LLM to assist with coding. Vide coding is just accepting what ever slop it outputs and saying LGTM. You are not going to get quality code that way. You need to review what it does. I often find that it uses outdated libraries and deprecated functions.

Some ways an LLM can assist with coding: I recently needed to refactor a bunch of code. Claude was very helpful this and it completed in about 5 minutes what would have taken me a couple of hours by hand.

Also they are very handy when using new frameworks and libraries. As we all know documentation for open source projects is often lacking. Just yesterday I ran into this. I pointed Claude at the projects GitHub repo and had the answers to my questions in just a couple of minutes. Manually I would have been spending a hour or two reading the code to figure out what I needed.

They are very handy when debugging. Get a weird hours that makes no sense. Instead of banging your head against the wall for a few hours, an LLM can help you find the problem much quicker.
