In this tutorial, we introduce the Gemini Agent Network Protocol, a powerful and flexible framework designed to enable intelligent collaboration among specialized AI agents. Leveraging Google’s Gemini models, the protocol facilitates dynamic communication between agents, each equipped with distinct roles: Analyzer, Researcher, Synthesizer, and Validator. Users will learn to set up and configure an asynchronous agent network, enabling automated task distribution, collaborative problem-solving, and enriched dialogue management. Ideal for scenarios such as in-depth research, complex data analysis, and information validation, this framework empowers users to harness collective AI intelligence efficiently.

import google.generativeai as genaiWe leverage asyncio for concurrent execution, dataclasses for structured message management, and Google’s Generative AI (google.generativeai) to facilitate interactions among multiple AI-driven agents. It includes utilities for dynamic message handling and structured agent roles, enhancing scalability and flexibility in collaborative AI tasks.

We define the core structures for agent interaction. The AgentType enum categorizes agents into four distinct roles, Analyzer, Researcher, Synthesizer, and Validator, each with a specific function in the collaborative network. The Message dataclass represents the format for inter-agent communication, encapsulating sender and receiver IDs, message content, type, and optional metadata.

The GeminiAgent class defines the behavior and capabilities of each agent in the network. Upon initialization, it assigns a unique ID, role type, and a reference to the agent network and loads the Gemini 2.0 Flash model. It uses role-specific system prompts to generate intelligent responses based on incoming messages, which are processed asynchronously through a queue. Each agent maintains a context memory to retain recent interactions and can either respond directly, send targeted messages, or broadcast insights to others. The run() method continuously processes messages, promotes collaboration by occasionally initiating responses to other agents, and manages message handling in a non-blocking loop.

The AgentNetwork class manages the coordination and communication between all agents in the system. It allows dynamic addition of agents with unique IDs and specified roles, maintains a log of all exchanged messages, and facilitates message routing to the correct recipient. The network can initiate a collaborative task by sending the starting message to an Analyzer agent, and runs the full asynchronous event loop for a specified duration, enabling agents to operate concurrently and interactively within a shared environment.

The demo_agent_network() function orchestrates the entire agent workflow: it initializes an agent network, adds four role-specific agents, launches a cybersecurity task, and runs the network asynchronously for a fixed duration while tracking message exchanges and agent participation. Meanwhile, setup_api_key() provides an interactive mechanism to securely configure the Gemini API key, with tailored logic for both Colab and non-Colab environments, ensuring the AI agents can communicate with the Gemini model backend before the demo begins.

Finally, the above code serves as the entry point for executing the Gemini Agent Network Protocol. It begins by prompting the user to set up the Gemini API key, exiting if not provided. Upon successful configuration, the demo is launched. If running in Google Colab, it applies nest_asyncio to handle Colab’s event loop restrictions; otherwise, it uses Python’s native asyncio.run() to execute the asynchronous demo of agent collaboration.
In conclusion, by completing this tutorial, users gain practical knowledge of implementing an AI-powered collaborative network using Gemini agents. The hands-on experience provided here demonstrates how autonomous agents can effectively break down complex problems, collaboratively generate insights, and ensure the accuracy of information through validation.
