Downside of ChatGPT is that it makes stuff up, of course, even when you ask it for URLs.
A few days ago I was going to send a patch to Alpine Linux, and I remembered they had a document for how they want commit messages to be authored but couldn't remember the URL.
Google search results for "alpine linux commit message style doc" only returned garbage in the first ~50 results - pages from Alpine's wiki unrelated to commit message style, pages from other projects like the Linux kernel about their commit style, and batshit results like https://docs.ansible.com/ansible/latest/collections/communit... (happens to contain the word "commit").
So I asked ChatGPT "What is the URL of Alpine Linux's style guide for commit messages?" and it confidently told me it's https://gitlab.alpinelinux.org/alpine/aports/-/blob/master/C... , which does not exist. I replied "That is a 404" and it responded "I apologize for the inconvenience. Alpine Linux's style guide for commit messages may have been moved or updated since my last training data. To find the most current style guide for Alpine Linux's commit messages, you can visit their repository directly and look for the CONTRIBUTING.md file or [go read their documentation and figure it out yourself, paraphrased]". The first one is a lie - a file named CONTRIBUTING.md has never existed in the master branch of that repo, as git easily reveals. The second one is schizophrenic - it's telling me to read the same file I just told it doesn't exist. The third one is unhelpful.
I had to find it myself. (It's https://gitlab.alpinelinux.org/alpine/aports/-/blob/master/C... )
