NeMo Guardrails is an open-source toolkit for easily adding *programmable guardrails* to LLM-based conversational applications. Guardrails (or "rails" for short) are specific ways of controlling the output of a large language model, such as not talking about politics, responding in a particular way to specific user requests, following a predefined dialog path, using a particular language style, extracting structured data, and more.

[This paper](https://arxiv.org/abs/2310.10501) introduces NeMo Guardrails and contains a technical overview of the system and the current evaluation.

Requirements

Python 3.10, 3.11, 3.12 or 3.13.
