What are Kimi Code and Codex?

Kimi Code logo
Kimi Code

Kimi Code is an AI coding agent and command line tool built by Moonshot AI. It helps developers explore codebases, edit multiple files, run commands, and finish programming tasks from start to finish. Instead of just suggesting a line of code, it can plan a task, use tools, and work through it step by step.

It comes as a terminal based CLI, a VS Code extension, and an API that works with other coding tools. It supports very long context windows, so it can read and remember large projects, and it connects to external tools and data through MCP, skills, and plugins.

Kimi Code is open source, and some of the models behind it have open weights too.

Codex

Codex is an AI coding agent from OpenAI that can plan, write, test, and fix code with real autonomy. You describe a task in plain language, and Codex works through your project step by step, running commands, checking tests, and preparing changes for you to review.

It started as a tool for software engineers but has grown into a wider work assistant used by analysts, designers, and other non-technical teams too. Codex runs in isolated spaces, so it does not touch your main project files directly.

You can use it from a desktop app, a command line tool, inside your code editor, or through ChatGPT on the web, and everything stays in sync across each place you work.
