We use a few depending on the task (Codex, fine-tuned T5, Bert models, etc.). Constantly experimenting with different variations. Since we focus on solving narrower problems in more depth, it leaves more room for optimizing accuracy.

Have you been able to get your rate limit increased for code-davinci-002? It defaults to a very small amount.

I recommend trying davinci-003 as well.

Yeah, been messing with that a lot.
