I am not particularly bothered by the speed but the AI suggestion clutter is quickly becoming an issue for me :( I type fragments of a line and it will suggest the next 5-6 lines. They may not be outright wrong, but they might not represent the way I like to do things. Pressing Esc. and refocusing on what I was going to type in anyway is a disruptive experience.
I use VSCode more often than PyCharm nowadays (same reasons as TFA, it's just too heavy), but unless something has changed in the last couple of months, you can disable the AI completions
So why don't you turn it off? Toggling this is really easy.
In JetBrains I limit AI suggestions to just the rest of the line I'm currently writing, tends to work a lot better for me. I also use the older ML models.
I don't love that the AI suggestions seem to override completion of real/existing methods from the source code these days.
