FAQ
How does prompt versioning work?
Every change to a prompt is saved as a commit with a message, timestamp, and author. You can branch off any version, make changes, and merge back — just like Git for code.
What metrics does A/B testing track?
You can track accuracy, latency, cost per call, user ratings, and custom metrics via our API. The winning variant can be auto-promoted to main based on your threshold.
Can I use this with any LLM provider?
Yes. PromptVCS is provider-agnostic. It works with OpenAI, Anthropic, Mistral, Cohere, and any API-accessible model. You bring your own keys.
