Recently I’ve enabled AI summarization on my own site and see how it works. I noticed that one summarization contained an invalid link:
[keyd](https://man.arch linux.org/man/extra/keyd/keyd.1.en)
It was weird. So I checked the AI logs. It turned out there were quite a few extra spaces in the request, e.g. e nter, Ct rl, host s, etc.
FYI the post is written in Chinese but contains a few English words. The space also may be inserted between Chinese charaters.
