From Prompts to Agents: The Complete Tech Stack for 2026

Description

Stop building simple chatbots and start building AI Agents. In this tutorial, we break down the exact requirements, dependencies, and prerequisites you need to build autonomous digital employees in 2026. We move beyond basic LLM prompts into the "Action" phase of AI—exploring how agents reason, use tools, and execute complex workflows. Whether you are a developer looking to integrate LangChain or CrewAI, or a beginner curious about the Python tech stack, this guide covers the essential hardware, software, and logic loops (ReAct) required to deploy functional AI agents today. Core Requirements Covered: Environment: Python 3.10+ and VS Code setup. API Access: Managing keys for GPT-4o, Claude 4.5, and Groq. Orchestration: Choosing between LangGraph and CrewAI. Key Concepts: RAG (Retrieval-Augmented Generation) and Function Calling. #AIAgents #LangChain #CrewAI #Python #ArtificialIntelligence #SoftwareEngineering #AIAutomation #LLM #TechTutorial
