I'd love to try Codex if I could run it on a local GPU and finetune it for my own code. I'd even push to use it at work. But as we're writing in a niche language and our code is heavily problem domain dependent, I don't feel like making my workflow vulnerable to an external supplier, even aside the IP concerns.

Call me when I can download and finetune the weights, like I can with Stable Diffusion.
