Fine Tuning Codex Model

Can I fine-tune a Codex Model? I’m trying to use davicni-codex as the base model for fine tuning job, but I get this error: “Error: Invalid base model: davinci_codex (model must be one of ada, babbage, curie, davinci) (HTTP status code: 400)”

I’m ultimately trying to create a model that will write code for a robot, so I would also appreciate any help on somehow increasing Codex’s knowledge of this Github repo: GitHub - FIRST-Tech-Challenge/FtcRobotController as well as its forks, thanks.

Thanks in Advance
