Anthropic Courses
Official courses on prompting, tool use, and real-world Claude apps.
Anthropic's official courses on prompt engineering, tool use, and building real-world Claude apps. Free, GitHub-hosted, with code labs covering topics from first API calls to multi-step agents.
What it does
- Five courses in one repo, with a suggested order: API fundamentals, prompt engineering interactive tutorial, real world prompting, prompt evaluations, tool use
- The interactive tutorial also ships an AWS Workshop version; real world prompting has a Google Vertex variant
- Prompt evaluations teaches writing production prompt evaluations, not just offline examples
- Tool use covers implementing tool calling in workflows with Claude end to end
When to use it
The default onboarding track for engineers new to the Claude API — work through it in order before writing production prompts.
Getting started
git clone https://github.com/anthropics/courses.git cd courses # start with anthopic_api_fundamentals/README.md # (per the repo's suggested order)
Things to know
The README notes the courses often favor the lowest-cost model, Claude 3 Haiku, to keep API costs down for students — you can substitute other Claude models if you prefer.
