Build your own Claude Code
Learn about LLM APIs, tool calling, agent loops and more
This challenge is free to try when it's in beta. We keep challenges in beta for a few weeks to gather feedback.
Claude Code is a terminal-based AI coding assistant that uses Large Language Models (LLMs) to understand code and complete programming tasks. In this challenge, you'll build your own Claude Code that is capable of editing files, running commands, and iterating until the task is done.
Along the way, you'll learn about LLM APIs, tool calling, agent loops, and how to integrate multiple tools into an AI assistant.
