1) https://github.com/domino14/Webolith/pull/523/files (Yes, the CSS file sucks. I tried multiple times to add dark mode to this legacy app and I wasn't able to. This works, and is fine, and people are using it, and I'm not going to touch it again for a while)
2) https://github.com/domino14/macondo/pull/399 - A neural net for playing Scrabble. Has not been done before, in at least an open-source way, and this is a full-fledged CNN built using techniques from Alpha Zero, and almost entirely generated by ChatGPT o3. I have no idea how to do it myself. I've gotten the net to win 52.6% of its games against a purely static bot, which is a big edge (trust me) and it will continue to increase as I train it on better data. And that is before I use it as an actual evaluator for a Monte Carlo bot.
I would _never_ have been able to put this together in 1-2 weeks when I am still working during the day. I would have had to take NN classes / read books / try many different network topologies and probably fail and give up. Would have taken months of full-time work.
3) https://github.com/woogles-io/liwords/pull/1498/files - simple, but one of many bug fixes that was diagnosed and fixed largely by an AI model.
