Aren't we talking about, say, GitHub Copilot? That's integrated into Visual Studio/VSCode. I just started using it again as they've done some small upgrades, and the results can often be phenomenal. Like, I will visualize an entire block of code in my mind, and I'll type the first couple of characters and the entire block will just appear. I'm literally that predictable.

Copilot is only using GPT3.5 for most of the results though, seemingly. I'd be more excited if they would update the API they're using.
