I've been using this or something similar internally for months and love it. The thing that gets downright spooky is the comments believe it or not. I'll have some method with a short variable name in a larger program and not only does it often suggest a pretty good snippet of code the comments will be correct and explain what the intent behind the code is. It's just a LLM but you really start to get the feeling the whole is greater than the sum of the parts.
