について OpenAI Codex CLI

Codex CLI is OpenAI's open-source, terminal-native coding agent. It reads and reasons about your local repository, edits files, runs commands, and completes multi-step engineering tasks with an agentic loop. Powered by the codex model family and running locally, it offers flexible autonomy modes (suggest, auto-edit, full-auto) and supports bring-your-own API key. It competes directly with Claude Code and Aider in the CLI coding-agent space.

よくある質問

Is Codex CLI free?

Yes, Codex CLI is open source and free to use. You pay only for the underlying OpenAI API calls via your own API key.

Codex CLI vs Claude Code?

Both are terminal coding agents. Codex CLI is open-source and uses OpenAI models with configurable autonomy modes, while Claude Code uses Anthropic's Claude models and requires an Anthropic plan. Codex CLI gives more control over model cost.
