Is the AI Agents Academy completely free?

Yes, 100% free. No sign-up, no credit card. All 13 modules, 58 lessons, 9 terminal labs, and 115 quiz questions are accessible immediately. Your progress saves locally in your browser.

How is Infinity AI Agents Academy different from vendor-locked agent courses?

Unlike single-framework platforms (such as LangChain Academy or CrewAI University) that tie you to a single proprietary ecosystem, Infinity Tech Stack's AI Agents Academy is a 100% free, vendor-neutral engineering curriculum. It teaches the complete production stack across ReAct loops, LangGraph, CrewAI, Google ADK, OpenAI Agents SDK, A2A protocol, and Model Context Protocol (MCP) integration with in-browser terminal labs and zero sign-up required.

What topics does the AI Agents Academy cover?

The course covers agent fundamentals, ReAct loops, Plan-and-Solve, tool use & function calling, MCP integration, Agentic RAG, multi-agent systems (CrewAI, LangGraph), A2A protocol, Google ADK, agent memory, safety & guardrails, red teaming, CI/CD for agents, and production observability.

What is the A2A protocol?

A2A (Agent-to-Agent) is Google's open protocol for enabling interoperability between AI agents. It allows agents from different vendors and frameworks to discover each other, exchange capabilities via Agent Cards, and delegate tasks securely.

Google ADK (Agent Development Kit) is an open-source framework for building, orchestrating, and deploying AI agents. It supports Python, Go, Java, and TypeScript, and integrates with MCP for tools and A2A for agent-to-agent communication.

Do I need any prerequisites?

Basic programming knowledge is helpful but not required. The course starts from absolute fundamentals (what is an agent?) and progressively advances to expert-level topics like multi-agent orchestration and production safety.

Does the AI Agents Academy include hands-on labs?

Yes. Hands-on terminal labs are built into the lessons - build the minimal agent loop, scaffold a CrewAI crew, and launch LangGraph dev using real, vendor-verified commands, with objectives, hints, solutions, and XP rewards. No sign-up or setup needed.

What is the recommended approach for beginners learning to build AI agents?

Build a simple while-loop from scratch without frameworks — Building a raw while-loop from scratch helps you understand the fundamental reasoning/acting cycle before abstractions hide the details.

Frameworks & Ecosystems

The agent ecosystem is rapidly expanding. Here is a breakdown of the leading frameworks in 2026:

Framework	model	Best For
LangGraph v1.2+	Graph-based state machines	Production systems, native MCP integration, LangGraph Cloud for managed deployment.
CrewAI	Role-based teams	Multi-agent workflows simulating human departments.
AG2 (AutoGen fork)	Community-maintained async multi-agent	Open-source successor to AutoGen — group chat and code generation scenarios.
OpenAI Agents SDK	Lightweight production SDK	Handoffs, guardrails, Native Sandboxing, and Long-Horizon use.
Vercel AI SDK / ecosystem	App-first framework tooling	Common choice for shipping agentic web products with strong DX and deployment tooling.
Managed Agent Runtimes	Hosted cloud execution	Provider-managed sessions, tool orchestration, and operational controls for production agents.
Google A2A Protocol	Agent-to-Agent messaging	Cross-framework interoperability via Agent Cards & task delegation.

Note: Building a raw agent from scratch (a simple while loop) is strongly recommended for learning before adopting complex abstractions like LangChain or CrewAI.
