Zero-to-First: Beginner's Learning Path for AI Large Language Models

When I revisited this roadmap, the first thing I wanted to add was learning sequence. Many learners jump straight into parameters, leaderboards, and model names—only to get lost in jargon before even getting a local environment up and running. My approach is to start by running a small, locally executable model first—then circle back to learn foundational concepts like Transformers, RAG, and fine-tuning. That way, every concept comes with a concrete, working mental image.

This guide serves best as an index for the full tutorial series. After reading it, write down three things:

• Your computer’s hardware configuration,
• The specific task you most want to solve,
• The amount of time you can realistically commit to learning.

With those clarified, your later decisions—about using Ollama, selecting local models, building knowledge bases, or leveraging remote compute—will be grounded in your context—not just trending tools.

Below is a detailed Zero-Baseline Learning Roadmap for AI Large Models, designed to take you from foundational math and programming all the way through machine learning, deep learning, and finally to core large-model technologies and hands-on projects. The roadmap is structured progressively—balancing theoretical rigor with practical implementation.
