# Anthropic, Mistral, etc.

With Literal's integration capabilities, you can seamlessly monitor all the [providers](https://python.langchain.com/docs/integrations/platforms/) supported by Langchain. This allows for a unified observability experience across different AI models and services, ensuring that you can track and analyze the performance and usage of each provider within the Literal platform.

You can thus monitor Anthropic, Mistral, and many other LLM providers.

  ```typescript TypeScript

  const literal_client = new LiteralClient(process.env.LITERAL_API_KEY);
  const cb = literal_client.instrumentation.langchain.literalCallback();

  // Example of using the callback
  const message = new HumanMessage({ content: "What is the capital of France?" });

  const model = new ChatAnthropic({
    anthropicApiKey: process.env.ANTHROPIC_API_KEY,

    console.log(response)
  }).catch(error => {
    // Handle any errors here
