Connecting to LangChain<\/strong><\/p>\n

Carlo can integrate with LangChain to monitor and enforce governance policies across your AI pipelines.<\/p>\n

This allows you to validate prompts, responses, and model outputs before they reach the user.<\/p>\n

Prerequisites<\/p>\n

Before connecting Carlo to LangChain, ensure:<\/p>\n

\u2022 Carlo SDK is installed
\n\u2022 LangChain is installed
\n\u2022 You have your Carlo API key<\/p>\n

Step 1<\/strong>: Install Dependencies<\/p>\n

Install both Carlo and LangChain.<\/p>\n

pip install carlo-ai langchain<\/p>\n

Step 2<\/strong>: Import Libraries<\/p>\n

Import the required modules.<\/p>\n

import carlo
\nfrom langchain.llms import OpenAI<\/p>\n

Step 3<\/strong>: Initialize Carlo Guardian<\/p>\n

Create a Guardian instance.<\/p>\n

guardian = carlo.Guardian(
\napi_key=”YOUR_API_KEY”
\n)<\/p>\n

Step 4<\/strong>: Wrap Your LangChain Model<\/p>\n

Connect the LangChain model with Carlo governance.<\/p>\n

llm = OpenAI()<\/p>\n

secured_llm = guardian.wrap(llm)<\/p>\n

Step 5<\/strong>: Send a Prompt<\/p>\n

Now all prompts will pass through Carlo’s policy engine.<\/p>\n

response = secured_llm(“Explain artificial intelligence.”)<\/p>\n

print(response)<\/p>\n

What Happens Now<\/strong><\/p>\n

Carlo will automatically:<\/p>\n

\u2022 Scan prompts for unsafe input
\n\u2022 Enforce governance policies
\n\u2022 Log all requests for auditing<\/p>\n

Next Step<\/strong><\/p>\n

Once LangChain is connected, you can enable logging and monitoring.
