AG2 Async Agent Chat with Automated Responses

This notebook demonstrates how to leverage asynchronous programming with AG2 agents to create automated conversations between AI agents, eliminating the need for human input while maintaining full traceability.

​
Overview

This notebook demonstrates a practical example of automated AI-to-AI communication where we:
  1. Initialize AG2 agents with OpenAI’s GPT-4o-mini model
  2. Create custom async agents that simulate human-like responses and processing delays
  3. Automate the entire conversation flow without requiring manual intervention
  4. Track all interactions using AgentOps for monitoring and analysis
By using async operations and automated responses, you can create fully autonomous agent conversations that simulate real-world scenarios. This is particularly useful for testing, prototyping, and creating demos where you want to showcase agent capabilities without manual input.
