Codex Zero-Foundation Newbie Practical Course: Deep LLM Prompt Teaching, Skill Workflow Building, Multi-Scenario Deployable Tutorial

Course intro
This Codex newcomer practical course is built for zero-foundation learners. It breaks down large-model and Codex core logic from scratch and avoids AI-use pitfalls. It explains TOKEN, multi-turn dialogue, model hallucination and other underlying concepts, contrasts Codex with an ordinary chat box, and hands-on teaches basic settings, precise prompt refinement, messy-information sorting, proposal generation and other core operations. It also covers Obsidian notes setup, AI-engine integration, multi-platform content creation, with emphasis on Skill plugin install/create/optimize and workflow chaining. It covers video editing, PPT making, AI video generation and other practical scenarios — empowering students to build their own automated workflows for industry use.
