Check out the full Udemy course (with complete source code) available now at a discounted price. https://www.udemy.com/course/agentic-ai-with-google-adk-mcp-servers/?referralCode=1D4127421535C3024964 Description In this video, we dive into LLM Interaction Callbacks in Google’s Agent Development Kit (ADK). These powerful hooks allow you to intercept and control what happens before an LLM is called and after a response is returned. You’ll learn: What the before_model_callback and after_model_callback hooks are and when they fire. How to implement them to inspect inputs, modify prompts, validate outputs, or replace model results entirely. Practical examples in Python/Java showing how to manage model calls within ADK agent workflows. Best practices for using model callbacks: logging, guardrails, pre- and post-processing, and custom workflows. Whether you’re building an intelligent agent with custom logic or enforcing safety and tracking around your LLM calls, this tutorial gives you the deep dive you need.
