MLflow Prompt Registry
Version prompt templates like code, with aliases for production and automated optimisation.
Why it is worth watching
Prompts are the part of a generative application that changes most and is versioned least.
What Beta promises
Open to most customers but not for production: support runs through engineering, and the shape of it can still move. On by default on Premium, off on Enterprise.
| Who can use it | Most customers |
|---|---|
| Production use | No |
| Support | Engineering only |
| On by default | Premium yes, Enterprise no |

Where to read more
We wrote it up: Prompt registry — The MLflow prompt registry stores prompt templates as versioned Unity Catalog objects with aliases for production, so a prompt change can be evaluated and rolled back like a model version. That page carries the Beta label while this entry does.
