Agentic AI Foundations: Master LLM APIs for QA, Developers

About this course

Stop chasing AI buzzwords. Start with what actually works: LLM APIs.Everyone talks about "Agentic AI" and "AI Agents," but here's the truth: You can build AI-powered applications by just calling LLM APIs. No PhD required. No ML training. No complex infrastructure.This course teaches the foundation every production AI system is built on: direct LLM API usage with OpenAI and Gemini.What You'll Learn:Make your first LLM API call in 5 minutesUnderstand response structures and data extractionMaster system prompts and temperature controlManage tokens and optimize costsWork with context windows effectivelyCompare OpenAI vs Gemini APIsBuild unified clients for multi-provider strategiesApply LLM APIs to real-world testing scenariosWho This Is For:QA Engineers, Developers, DevOps Engineers, Tech Leads, Product Managers, and anyone in tech who wants to understand how AI actually works in production.Prerequisites:Basic Python knowledge (if you know any programming language, you're good!)**Your AI Journey Starts Here**The AI revolution is happening now, and you don't need a computer science degree to be part of it. Every production AI application you see—ChatGPT integrations, AI-powered testing tools, intelligent automation—they all start with simple API calls. This course gives you the exact foundation used by professional developers building real-world AI solutions. Stop watching from the sidelines. Start building today.
