A practical guide to the best free AI courses, tools, and learning paths from the companies and universities shaping the field.
I keep seeing the same problem with AI learning.
There are courses everywhere.
Google has courses. Microsoft has courses. OpenAI has an academy. Anthropic has Claude courses. NVIDIA has training. MIT and Harvard have free university material. Hugging Face has open courses. YouTube has world-class lectures.
But a long list of links is not the same thing as a learning path.
So I made this as a map.
Not by company.
By what you actually need to learn first.
Start with AI basics. Then learn LLMs. Then prompting. Then agents. Then automation, RAG, MCP, Claude Code, and production AI systems.
I have also added my own Opinion AI guides after each section. The free resources below are the raw learning material. My guides are where I try to organize, simplify, and connect the best parts into one practical system.
A $10 subscription gives you access to 74 practical AI guides covering agents, Claude, Codex, MCP, RAG, automations, coding, workflows, business use cases, and the parts of AI that are actually useful for work.
1. Learn AI basics first
Start here if you are new.
This layer is not about coding. It is about understanding what AI is, where it helps, where it fails, and how to use it without getting lost in hype.
Best free resources
- Elements of AI
- Google AI Training
- IBM SkillsBuild Artificial Intelligence
- Microsoft AI for Beginners
- Meta AI Resources
My suggestion is simple.
Take Elements of AI first. Then Google AI Training. Then Microsoft AI for Beginners if you want more depth.

2. Learn how LLMs work
LLMs are the engine behind ChatGPT, Claude, Gemini, DeepSeek, Llama, and many AI tools.
You do not need to understand every math detail.
But you should know tokens, context windows, transformers, training, fine-tuning, reasoning, hallucination, and why a model sometimes sounds confident while being wrong.

- Intro to Large Language Models
- Stanford CS25: Transformers United
- MIT Artificial Intelligence
- Build a Large Language Model from Scratch
This is the layer that makes everything else easier.
Once you understand LLMs, prompting makes more sense. Agents make more sense. RAG makes more sense.

3. Learn prompting as work design
Prompting is not magic wording.
It is task design.
Good prompting means giving the model context, role, examples, constraints, output format, and a way to check its own work.
This is the skill every reader should learn, even if they never write code.
Best free resources
- OpenAI Prompt Engineering Guide
- Anthropic Prompt Engineering
- Google Gemini Prompt Design Strategies
- DAIR AI Prompt Engineering Guide
- AWS Foundations of Prompt Engineering
The simple rule is this.
Do not ask AI to guess your task.
Give it the work like you would give it to a smart assistant on the first day.

4. Learn AI agents
This is the most important category right now.
A chatbot answers.
An agent works through steps.
It can plan, use tools, call APIs, search files, run code, check results, and continue the task.
This is where AI starts moving from conversation to work.
Best free resources
- Hugging Face AI Agents Course
- Microsoft AI Agents for Beginners
- OpenAI Agents Docs
- Anthropic Building Effective Agents
- Google Agents Whitepaper
Start small.
Build one agent that does one job.
Then add tools.
Then add memory.
Then add evaluation.

5. Learn automation and workflows
This is where AI becomes useful for business.
Not in a demo.
In daily work.
Research flows. Email flows. Lead flows. Content flows. Reporting flows. Customer support flows. Invoice checks. Meeting summaries. Internal dashboards.
Agents need workflows around them.
Best free resources
Learn automation early.
It teaches you how work actually moves from one step to another.

6. Learn Claude and Claude Code
Claude is becoming one of the most useful AI systems for writing, research, coding, documents, analysis, and agentic work.
Claude Code is even more important because it shows where coding is going.
The old way was writing every line yourself.
The new way is setting context, giving rules, checking changes, and letting the coding agent work inside a clear system.

- Anthropic Academy
- Claude Code Docs
- Anthropic Courses on GitHub
- Claude Code Best Practices
If you write, research, build, or manage projects, learn Claude seriously.
It is not only a chatbot.
It can become a work system.

7. Learn MCP and tool-connected AI
MCP means Model Context Protocol.
Simple meaning: it helps AI systems connect to tools, files, databases, apps, and services in a cleaner way.
This matters because AI is leaving the empty chat box.
The next layer is connected AI.
AI that can use tools.
AI that can read your files.
AI that can work inside your software.
AI that can call the right system at the right time.
Best free resources
- Official MCP Documentation
- Anthropic MCP Course
- DeepLearning.AI MCP with Anthropic
- OpenAI Tools Docs
- Google Gemini Function Calling
Learn MCP because it is part of the agent infrastructure story.
Not every reader needs to build MCP servers today.
But every serious AI learner should understand what it means.

8. Learn RAG and AI memory
RAG means Retrieval Augmented Generation.
Simple meaning: the model does not only answer from its training. It retrieves useful information from your files, database, docs, notes, or knowledge base before answering.
This is how AI becomes useful inside a real company.
A model alone does not know your refund policy, bakery process, product list, meeting notes, customer emails, or internal SOPs.
RAG gives AI access to the right knowledge.

- LlamaIndex RAG From Scratch
- LangChain RAG Tutorial

This is one of the most practical AI skills.
If you understand RAG, you understand why business AI needs knowledge systems, not only better prompts.

9. Learn machine learning and AI engineering
You can use AI without becoming a machine learning engineer.
But if you want deeper understanding, this layer matters.
Machine learning teaches you the older foundation.
AI engineering teaches you how to build systems that actually work.
Testing. Evaluation. Deployment. Monitoring. Cost. Safety. Data. Feedback loops.
This is where serious builders should spend time.

Pick one serious path.
Finish it slowly.
Do not jump between ten tabs.

The simple path I would follow
Here is the clean order.
Week 1: Elements of AI
Week 2: Google AI Training or IBM SkillsBuild
Week 3: Hugging Face LLM Course
Week 4: OpenAI and Anthropic prompting guides
Week 5: Hugging Face Agents Course
Week 6: Microsoft AI Agents for Beginners
Week 7: n8n or Make Academy
Week 8: Pinecone or LlamaIndex RAG guide
Week 9: Anthropic Academy and Claude Code docs
Week 10: MCP documentation
Week 11: Google Machine Learning Crash Course
Week 12: Made With ML or Full Stack Deep Learning
That is enough to build a serious foundation.
Not a fake AI guru foundation.
A useful one.
My honest take
Free AI education is already good enough to start.
The issue is not access.
The issue is order.
If you only save links, nothing changes.
If you follow a path, build small things, and keep connecting the pieces, your understanding compounds.
Start with basics.
Then LLMs.
Then prompts.
Then agents.
Then workflows.
Then RAG and MCP.
Then production thinking.
