How to use Google Agent ADK?
Google is trying to regain its crown as the most tech-savvy firm. First, they released Gemini 2.5 Pro, the best LLM so far. Now, they have come up with a Google Agent SDK which can help you create multi-agent orchestration pipelines with ease in production.

Key Features of Google’s Agent ADK:
1. Core Purpose
- Open-source framework for building autonomous multi-agent systems.
- Simplifies end-to-end development of production-ready agentic applications.
- Powers Google’s own agents (e.g., Agentspace, Google Customer Engagement Suite).
2. Core Pillars
- Build: Modular, scalable multi-agent systems.
- Interact: Human-like conversations with multimodal (audio/video) streaming.
- Evaluate: Systematic performance assessment (step-by-step execution & response quality).
- Deploy: Containerized deployment anywhere (optimized for Google Cloud).
3. Multi-Agent Capabilities
- Hierarchical Composition: Agents can delegate tasks to specialized sub-agents.
- Dynamic Orchestration:
Workflow agents (sequential, parallel, loop).
LLM-driven dynamic routing (e.g., LlmAgent transfer).
- Auto-Delegation: Agents intelligently route tasks based on descriptions.
4. Model & Tool Ecosystem
Model Agnostic:
Supports Gemini, Vertex AI Model Garden, and third-party models via LiteLLM (Anthropic, Meta, Mistral, etc.).
Rich Tool Integration: Pre-built tools (Search, Code Execution).
Model Context Protocol (MCP) tools.
Third-party libraries (LangChain, LlamaIndex).
Other agents as tools (LangGraph, CrewAI).
5. Developer Experience
- Pythonic API: Simple agent definition with LlmAgent and tools.
- CLI & Web UI: Local testing, debugging, and visualization.
- Bidirectional Streaming: Real-time multimodal (audio/video) interactions.
6. Evaluation Framework
- Test Case Validation: Evaluate agent responses & execution paths.
- Programmatic & CLI Testing: AgentEvaluator.evaluate() or adk eval.
7. Deployment Flexibility
- Containerized: Deploy anywhere (Docker, Kubernetes).
- Google Cloud Optimized:
Native Vertex AI Agent Engine integration.
Enterprise-grade runtime with Gemini models (e.g., Gemini 2.5 Pro Experimental).
Pre-built connectors (AlloyDB, BigQuery, Apigee, NetApp).
How does it compare with Crew.AI, Langraph, and Autogen?
The framework is looking good and compares well with existing stable multi-agent orchestration frameworks.






Summarizing
Key Takeaways:
- Google ADK excels in production-ready, cloud-integrated deployments with strong evaluation tools
- LangGraph is ideal for complex, stateful workflows requiring precise control (e.g., error recovery, cycles)
- CrewAI simplifies role-based collaboration but lacks advanced orchestration
- AutoGen shines in conversational/code-generation tasks but struggles with scalability.
How to use Google’s Agent SDK?
- The codes are simple. Pip install ‘google-adk’ and create a file ‘temp.py’
#pip install google-adk
# my_agent/agent.py
from google.adk.agents import Agent
from google.adk.tools import google_search
root_agent = Agent(
name="search_assistant",
model="gemini-2.0-flash-exp", # Or your preferred Gemini model
instruction="You are a helpful assistant. Answer user questions using Google Search when needed.",
description="An assistant that can search the web.",
tools=[google_search])
2. Create the below file and run cmd command

Concluding,
Google’s open-source Agent SDK lets developers build multi-agent systems for real-world tasks. Key features include modular design, human-like interactions (text/audio/video), task delegation between agents, and seamless deployment on Google Cloud. It supports Gemini and other AI models, pre-built tools (search, code execution), and integrates with LangChain/LlamaIndex.
vs. Competitors
Google ADK: Best for scalable cloud production with strong testing tools.
LangGraph: Ideal for complex workflows needing error handling.
CrewAI: Simplifies role-based teamwork but lacks scalability.
AutoGen: Great for code/chat generation, not large-scale systems.
Quick Start
Install via pip install google-adk, create an agent with tools (e.g., Google Search), and deploy. Example agents handle web searches or workflows. See GitHub for guides.
Hope you try out the framework.
