anthropics/courses

What is this?

anthropics/courses is a collection of five educational courses created by Anthropic (the company behind the Claude AI models). The courses teach you how to work with Claude's software development kit (SDK) — essentially, how to build applications that use Claude.

The five courses, in suggested order

1. Anthropic API fundamentals — Covers the basics: getting an API key, adjusting model parameters, writing prompts that include images (multimodal), and handling streaming responses.

2. Prompt engineering interactive tutorial — A step-by-step guide to the key techniques for writing effective prompts. (An AWS Workshop version is also available.)

3. Real world prompting — Shows how to apply prompting techniques to complex, real-world scenarios. (A Google Vertex version is available.)

4. Prompt evaluations — Teaches you how to write evaluations that measure the quality of your prompts in a production setting.

5. Tool use — Covers everything needed to implement tool use (letting Claude call external functions or APIs) in your workflows.

Important note for learners

The courses deliberately use Claude 3 Haiku, Anthropic's lowest-cost model, to keep API expenses down while you follow along. The README explicitly says you're free to use other Claude models if you prefer.

Bottom line

If you want to learn how to build with Claude — from the basics to advanced techniques like tool use and prompt evaluation — this repository is a structured, free learning path that walks you through it step by step.
