Ever felt like your complex LangChain applications are a "black box"? Want to understand exactly what's happening under the hood, track costs, debug issues, or trigger custom actions at specific moments? That's where Chain Lifecycle Events in LangChain become indispensable!

In this advanced LangChain tutorial, we'll unlock the power of Callback Handlers – LangChain's robust mechanism for interacting with the execution flow of your chains, runnables, and agents. You'll learn how to leverage these lifecycle events to gain deep insights, implement custom logging, track token usage, handle errors gracefully, and build truly observable and controllable LLM applications.

Mastering Chain Lifecycle Events and Callback Handlers is crucial for anyone building production-grade LLM applications with LangChain. This video will transform your ability to monitor, debug, and enhance your AI systems!
