Decoding LLM Fine Tuning

Ever wondered how massive AI models are tailored for specific tasks without needing a supercomputer? In this video, we break down the evolution of LLM fine-tuning from brute-force methods to bitwise efficiency. Whether you're a developer or an AI enthusiast, this guide covers everything you need to know about making AI accessible and efficient. What You’ll Learn: The Problem with Full Fine-Tuning: Why retraining 175 billion parameters is a barrier for most developers [00:16]. Quantization Explained: How "compressing" models from 32-bit to 8-bit saves memory and boosts speed [01:35]. LoRA (Low-Rank Adaptation): Discover the "rudder" technique that reduces trainable parameters by over 99.9% [03:12]. QLoRA: The ultimate combination of quantization and LoRA for single-GPU fine-tuning [04:15]. The Future with BitNet: Why 1-bit LLMs could bring powerful AI to your smartwatch [05:14].
