## About the Microservice

The microservice classifies jailbreak attempts from a user-supplied prompt.

The microservice uses the Ardennes model.
The model is a random forest that is trained by NVIDIA on the Snowflake Arctic Embed M Long model.
The model is the best-known, publicly-available model for detecting LLM jailbreak attempts.
