I just updated my PhpStorm to version 2024.1, and one of the big new features is the local AI autocomplete called "Full Line Code Completion". The press release made it sound super promising, especially since the AI's suggestions are double-checked by the IDE to filter out any unfit options.

But here's the real deal:
1) The new PhpStorm 2024.1 is pretty buggy. A lot of the standard features are broken, making it tough to work with.
2) The new Full Line Code Completion? It works about as well as you can see in the screenshot below.

I wanted to give the new local AI from JetBrains a longer test run, but unfortunately, the overall bugginess of PhpStorm 2024.1 forced me to roll back to version 2023.3.

It's sad but true: the first release of every new major version of PhpStorm has been too raw for the last couple of years. I always end up going back to the previous version. Looks like it's best to wait for a few minor updates before diving in.
