Integrating NeMo Guardrails: A Practical Guide with Code Examples

NeMo Guardrails operates through two primary components: the config.yml file and guardrails specified in COLANG format. Here's how they orchestrate the magic behind the scenes:

1. config.yml – The Configuration Blueprint: This YAML file is the blueprint of your AI model's behaviour. It contains:

  • General Options: Details like which LLMs to use, general instructions (akin to system prompts), sample conversations, active rails, and specific configuration options.
  • Rails: Implementations of guardrails in COLANG format, typically found in a dedicated rails folder.
  • Actions: Custom actions scripted in Python, located either in an actions.py module or an actions sub-package.
  • Knowledge Base Documents: Utilised in Retrieval-Augmented Generation (RAG) scenarios, these documents are stored in a kb folder.
  • Initialization Code: Custom Python code for additional initialization tasks, like registering new LLM types.

Consider this sample YAML configuration, designed for use with OpenAI's model. Remember to set your OpenAI API key in the environment variable


 - type: main
   engine: openai
   model: gpt-3.5-turbo-instruct
   temperature: 1.0
   top_p: 0
   top_k: 1
   tokens: 100
   beam_width: 1
   repetition_penalty: 1.0

2. COLANG – The Language of Guardrails: COLANG blends natural language with Python to design conversational guardrails. Its syntax includes blocks, statements, expressions, keywords, and variables. Key block types are user message blocks (define user ...), flow blocks (define flow ...), and bot message blocks (define bot ...). Here's an example of COLANG configuration:

# define greetings
define user express greeting
   "what's up?"

define flow greeting
   user express greeting
   bot express greeting
   bot ask how are you

define user ask off-topic
 "Can you tell me some good tourist places to visit around Mysore
 "Can you recommend a good restaurant nearby?"
 "What are the main highlights of the president's speech?"
 "How do I cook spaghetti?"

define bot explain cant off topic
 "I cannot answer your question because I'm programmed to assist only with questions related to products on this site."

define flow off-topic
 user ask off topic
 bot explain cant off topic

With the configurations in place, setting up NeMo Guardrails is straightforward:

from nemoguardrails import LLMRails, RailsConfig

# initialize rails config
config = RailsConfig.from_content(
# create rails
rails = LLMRails(config)

Let's put our setup to the test with a simple greeting:

res = await rails.generate_async(prompt="Hey there!")


Hi! How can I help you today?
How are you doing today?

Here, the response is guided by the greeting flow block in Colang. Now, let's test the guardrail for off-topic inputs:

res = await rails.generate_async(prompt="How do I cook spaghetti?")


I cannot answer your question because I'm programmed to assist only with questions related to products on this site. Is there anything else I can help you with?

Indeed, NeMo Guardrails proficiently managed the conversation, adhering to the defined parameters. With its comprehensive and flexible system, NeMo Guardrails is a robust solution for safely and responsibly managing LLM outputs. Its async-first design and compatibility with multiple LLMs make it an attractive tool for a broad spectrum of AI developers and applications.
