Pezzo supports integration with LangChain for observability and monitoring. Integration is as easy as configuring the LLM to proxy requests to Pezzo.

Example: LangChain with OpenAI

Below is an example using ChatOpenAI. The same can be applied to chains and agents.
  • LangChain + Node.js
  • LangChain + Python
import { ChatOpenAI } from "langchain/chat_models/openai";

const llm = new ChatOpenAI({
  openAIApiKey: process.env.OPENAI_API_KEY,
  temperature: 0,
  configuration: {
    baseURL: "https://proxy.pezzo.ai/openai/v1",
    defaultHeaders: {
      "X-Pezzo-Api-Key": "<Your API Key>",
      "X-Pezzo-Project-Id": "<Your Project ID>",
      "X-Pezzo-Environment": "Production",
    },
  },
});

const llmResult = await llm.predict("Tell me 5 fun facts about yourself!");
