This repository serves as a beginner-friendly guide to AI and LLM large models, walking users from basic API calls through to local model deployment and fine-tuning. It provides tutorial content and demo code covering AI video summarization, LLM fine-tuning, and AI image generation. The project also includes a code playground for experimenting with AI scripts, paper notes on foundational LLM papers, and mirrors the Chinese assignments for Lee Hung-yi’s 2024 Generative AI Introduction course. A Docker image is provided to help users quickly set up a deep learning environment.
