This isn't completely answering the question you asked but https://www.blackbox.ai/ https://www.blackbox.ai/ was my favorite after testing out some free ones. I know I liked it better than TabNine, CodeGPT and Codeium in VS Code. I'm pretty sure I tested a few others from the top of list of extensions when you search the extension marketplace, but I forgot which ones. Blackbox just seems more intuitive in use and had better answers. They don't have many followers on Twitter, I'm surprised more people aren't talking about it.
