Disclaimer: I work for MosaicML (MosaicML is the creator of the training platform used by Replit).
Training these models from scratch on your domain specific data is not as expensive as one might think. We have provided some cost estimates in our blogs.
Do you have any examples on how to train a model that can write code but in a specific domain? Eg I only want to train it on a specific set of code. Eg let’s say functional React components in TypeScript.
