04 - Fine-Tuning LLMs: LoRA, QLoRA, and PEFT for Model Personalization

Adapt LLMs to your data: full fine-tuning vs LoRA (Low-Rank Adaptation). QLoRA: LoRA + quantization for small GPUs. PEFT (Parameter-Efficient Fine-Tuning) overview. When it makes sense vs prompt engineering. Costs: data prep, GPU, time. Hugging Face ...
