Each time you add examples and retrain an AI model, you get a new version, and someone has to know which one is live. If you fine-tune on OpenAI or Gemini directly, you train, deploy and track each version yourself, which is work that has nothing to do with your task. Promptrepo does it for you: a new model starts at version 1, and the Promptrepo add-on in Google Sheets shows the live version and its history.
Let's start. Create your AI model and you will see its version in its name.
