Interesting, have you used it/found it to be usable?
I use IntelliJ myself, but it's not known for being a lean beast. With the addition of stuff like test containers and a few plugins, I'd be suprised if my machine didn't melt adding a local LLM too.
I mainly use PyCharm and I found the auto-complete to be good. It doesn't always kick in when I expect but some of the suggestions have been surprisingly complex and correct.
