# The Free Agent-Building Courses Everyone's Sharing Right Now: Anthropic, Andrew Ng, and Google, Compared

> Three big free-or-cheap agent courses are circulating this month, and they teach different things. Here's what each one actually covers, how long it takes, and which to pick based on what you're trying to build.

## Key takeaways

- Three free-or-low-cost agent-building courses are circulating widely this month, and they don't overlap as much as the hype implies — pick by what you want to build, not by whose logo is on it.
- 'Agent Skills with Anthropic' (DeepLearning.AI, taught by Anthropic's Elie Schoppik) is the narrowest and most practical: it teaches Agent Skills — folders of instructions that give an agent on-demand workflows — across Claude.ai, Claude Code, the Claude API, and the Agent SDK, and how to combine them with MCP and subagents.
- Andrew Ng's 'Agentic AI' course (DeepLearning.AI) is the broad foundations track: the durable agentic design patterns — reflection, tool use, planning, and multi-agent collaboration — that apply regardless of which framework you end up on.
- Google's free 'agentic engineering from scratch' material (a widely-shared ~1-hour walkthrough) is the build-your-own path: first agent, agent memory (short / persistent / long), long-running agentic loops, building your own MCP (MCP vs API), and multi-agent systems.
- The honest routing: take the Anthropic course if you're shipping on Claude and want reusable skills this week; take Ng's if you want vendor-neutral fundamentals that survive a framework switch; take Google's if you learn by building the loop yourself. Most builders benefit from Ng's patterns plus one hands-on course.

## At a glance

| Course | Who teaches it | Format & length | Level | What you build / leave with | Best if you |
| --- | --- | --- | --- | --- | --- |
| Agent Skills with Anthropic | Anthropic (Elie Schoppik), on DeepLearning.AI | Short course, ~1 hr, hands-on, free | Beginner–intermediate | Custom + pre-built Agent Skills across Claude.ai, Claude Code, Claude API, Agent SDK; skills + MCP + subagents | Ship on Claude and want reusable, on-demand workflows now |
| Agentic AI | Andrew Ng, on DeepLearning.AI | Longer structured course | Beginner–intermediate | The agentic design patterns — reflection, tool use, planning, multi-agent — vendor-neutral | Want fundamentals that survive a framework or model switch |
| Agentic engineering from scratch | Google (free video walkthrough, widely shared) | ~1 hr, watch-and-build, free | Intermediate | Your first agent, agent memory, long-running loops, your own MCP (MCP vs API), multi-agent | Learn by building the loop and the protocol yourself |

## By the numbers

- **3** — free-or-low-cost courses circulating widely this month
- **1 hr** — length of the two shortest (Anthropic skills, Google from-scratch)
- **4** — agentic design patterns Ng's course centers on — reflection, tool use, planning, multi-agent

Every few days this month, another "just dropped: a free course on building AI agents" post rockets around X. Three of them keep resurfacing — from Anthropic, Andrew Ng, and Google — and the reflex is to assume they're interchangeable and pick whichever has the most retweets. They aren't interchangeable. They teach genuinely different things, and picking wrong wastes the exact weekend you set aside to learn this.
> **The short answer:** Take **Agent Skills with Anthropic** if you're building on Claude and want reusable workflows you can ship this week. Take **Andrew Ng's Agentic AI** if you want vendor-neutral fundamentals that survive a framework switch. Take **Google's "agentic engineering from scratch"** if you learn by wiring the loop and the protocol yourself. If you have time for two, do Ng's patterns first, then one hands-on course.

What each one is actually for
**Agent Skills with Anthropic** is the narrowest and the most immediately useful. Taught by Anthropic's Elie Schoppik on DeepLearning.AI, it teaches one concrete mechanism: **Agent Skills** — folders of instructions that give an agent on-demand knowledge and workflows, so you stop re-explaining the same process every session. It walks through Anthropic's pre-built skills (Excel, PowerPoint, skill creation), building your own following best practices, and running them across Claude.ai, Claude Code, the Claude API, and the Agent SDK — then combining skills with MCP and subagents. If you're already on Claude, this is the course you can turn into shipped work fastest. (We went deeper on the founder angle in [what founders should take from Anthropic's Agent Skills course](/posts/anthropic-agent-skills-course-what-founders-should-take.html).)
**Andrew Ng's Agentic AI** is the foundations track. It's built around the durable **agentic design patterns** — reflection (the agent critiques its own output), tool use, planning, and multi-agent collaboration — that Ng has taught for a while and that hold regardless of whether you end up on [LangGraph](/stack/langgraph), [CrewAI](/stack/crewai), the [Claude Agent SDK](/stack/claude-agent-sdk), or your own loop. It's the least likely of the three to go stale, because it's about how agents are *shaped*, not which SDK is hot this quarter. If you only internalize one thing before writing code, make it these patterns.
**Google's "agentic engineering from scratch"** is the build-it-yourself path — a free, roughly one-hour walkthrough that keeps resurfacing on X. It starts from nothing and wires up: your first agent, **agent memory** (short-term, persistent, long-term), **agentic loops** for long-running agents, **building your own MCP** and when MCP beats a plain API, and multi-agent systems. It's the most hands-on-with-the-machinery of the three. That makes it a great *second* course — once you know the patterns, watching the loop and the protocol get built by hand is what makes them stick.
The honest routing
- **Shipping on Claude this week?** Anthropic's skills course. Shortest path from watching to a reusable skill in your repo.
- **Want knowledge that survives your next framework migration?** Ng's patterns. Frameworks churn; reflection-tool-use-planning-multi-agent doesn't.
- **Learn by building?** Google's from-scratch walkthrough, ideally after Ng's.
- **Have a weekend?** Ng first (the map), then one hands-on course (the terrain). Skip trying to do all three back-to-back — the hands-on courses overlap enough that a second one has diminishing returns.

The pattern worth noticing across all three: every one of them now treats **skills, memory, MCP, and multi-agent** as the core curriculum. Two years ago an "AI course" meant prompting. The free courses builders are sharing today assume you're building a *system* — which is a decent signal of where the floor for "knows how to build an agent" has moved. Whichever you pick, that's the level you're being asked to reach.

## FAQ

### Which free agent-building course should I take first?

It depends on your goal, not on the brand. If you're already building on Claude and want to ship reusable workflows this week, take 'Agent Skills with Anthropic' — it's the narrowest and most immediately applicable. If you want fundamentals that survive switching frameworks or models, take Andrew Ng's 'Agentic AI' course for the design patterns. If you learn best by building the agent loop and an MCP server yourself, Google's free 'agentic engineering from scratch' walkthrough is the hands-on path. Many builders pair Ng's patterns with one hands-on course.

### What is the 'Agent Skills with Anthropic' course about?

It's a short, free, hands-on course on DeepLearning.AI taught by Anthropic's Elie Schoppik. It covers Agent Skills — folders of instructions that equip an agent with on-demand knowledge and workflows so you don't re-explain the same process every time — and shows them in action across Claude.ai, Claude Code, the Claude API, and the Claude Agent SDK. It includes using Anthropic's pre-built skills (like Excel and PowerPoint), creating custom skills following best practices, and combining skills with MCP and subagents for more complex workflows.

### Is Andrew Ng's Agentic AI course different from the Anthropic one?

Yes, and they complement each other. Ng's 'Agentic AI' course teaches vendor-neutral foundations — the agentic design patterns of reflection, tool use, planning, and multi-agent collaboration — that apply no matter which framework or model you build on. The Anthropic course is narrower and Claude-specific: it teaches one concrete mechanism (Agent Skills) you can ship immediately. Fundamentals from Ng, applied technique from Anthropic.

### What does Google's 'agentic engineering from scratch' course cover?

The widely-shared free walkthrough runs about an hour and builds up from nothing: your first AI agent, agent memory (short-term, persistent, and long-term), agentic loops for long-running agents, building your own MCP and when to use MCP versus a plain API, and multi-agent systems. It's the most 'build the machinery yourself' of the three, which makes it a good fit once you understand the patterns and want to see the loop and the protocol wired by hand.

### Are these courses actually free?

The DeepLearning.AI short courses (including 'Agent Skills with Anthropic') are free to audit, and Google's 'from scratch' walkthrough is a free video. Some longer or certificate-bearing tracks — and separate paid programs on platforms like Udacity or Udemy — cost money, so check the specific enrollment page before assuming. The three compared here are the free-or-audit-free ones circulating this month.
