The software is free, but it looks like the trademark is not. So WordPress bans WP engine from some WordPress stuff b/c they aren’t technically WordPress. In other words, they’re free to use (and change) the software, but they can’t (or, rather, shouldn’t) use the name—according to WordPress. WP sues for usage anyway after they are barred from some event or something, but now WordPress is suing back, turning an unofficial dispute to a legal one.
Deep learning doesn’t stop at llms. Honestly, language isn’t a great use case for them. They are—by nature—statistics machines, so if you have a fuck load of data to crunch, they can work very quickly to find patterns. The patterns might not always be correct, but if they are easy to check, then it might be faster to use them and modify the result compared to doing it all yourself.
I don’t know what this person does, though, and it will depend on the specifics of the situation for how they are used.
