🧪 Fine-Tune LLMs & Build Real AI Agents — https://kode.wiki/4cHnB48 Prompt engineering is fragile. Users can override your system prompt, break character, and inject instructions you never intended. Fine-tuning actually changes the model's weights — embedding behavior directly into how it thinks. This video walks you through why fine-tuning beats prompt engineering for production AI agents, how LoRA and QLoRA make it feasible on consumer hardware, and how to build a Taco Drive-Through agent that stays on topic and resists jailbreaks — inside a real KodeKloud hands-on lab. No theory overload. Just structured, practical learning from the problem all the way to alignment testing. ───────────────────────────────────────── 📌 WHAT YOU'LL LEARN IN THIS VIDEO ───────────────────────────────────────── ✅ How prompt engineering gets hacked and why fine-tuning is the fix ✅ How RLHF turned GPT-3 into ChatGPT ✅ Real use cases: guaranteed JSON output, brand agents, and game NPCs ✅ How LoRA and QLoRA freeze base parameters and add lightweight adapter layers ✅ All 6 Fine-Tuning steps: prompt problem → data prep → LoRA config → training → evaluation → alignment 🧪 FREE HANDS-ON LAB — https://kode.wiki/4cHnB48 Practice everything in a real sandbox. No local setup, no credit card, no surprises. GPU environment, dependencies, and all lab tasks are pre-configured and ready to go. ⏱️ TIMESTAMPS 00:00 – Introduction to Fine-Tuning LLMs 00:45 – Prompt Engineering: What It Is and Why It Falls Short 01:40 – Fine-Tuning Explained 02:03 – Real Use Cases 02:45 – LoRA and QLoRA 03:12 – Lab Intro: Taco Drive-Through Agent 04:16 – Lab - Setting up the environment 04:35 – Task 1: The Prompt Engineering Problem 05:40 – Task 2: Preparing Training Data 06:20 – Task 3: Configuring LoRA 07:35 – Task 4: Training with LoRA 08:22 – Task 5: Test Fine-Tuned Agent 09:03 – Task 6: Create DPO Preference Data 10:11 – Key Takeaways #LLMFineTuning #LoRA #QLoRA #AIAgent #PromptEngineering #RLHF #KodeKloud #MachineLearning #GenerativeAI #DeepLearning #AITutorial #MLOps #OpenAI #FineTuneGPT #AIEngineering #HandsOnLab #LargeLanguageModels #AITraining #LearnAI #DevOpsAI #NLP #LLMTraining #ParameterEfficientFineTuning #CloudAI #AIJailbreak
