Addresses #16124 Problem: `codex --remote --cd <path>` canonicalized the path locally and then omitted it from remote thread lifecycle requests, so remote-only working directories failed or were ignored. Solution: Keep remote startup on the local cwd, forward explicit `--cd` values verbatim to `thread/start`, `thread/resume`, and `thread/fork`, and cover the behavior with `codex-tui` tests. Testing: I manually tested `--remote --cd` with both absolute and relative paths and validated correct behavior. --- Update based on code review feedback: Problem: Remote `--cd` was forwarded to `thread/resume` and `thread/fork`, but not to `thread/list` lookups, so `--resume --last` and picker flows could select a session from the wrong cwd; relative cwd filters also failed against stored absolute paths. Solution: Apply explicit remote `--cd` to `thread/list` lookups for `--last` and picker flows, normalize relative cwd filters on the app-server before exact matching, and document/test the behavior.
npm i -g @openai/codex
or brew install --cask codex
Codex CLI is a coding agent from OpenAI that runs locally on your computer.
If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run
codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.
Quickstart
Installing and running Codex CLI
Install globally with your preferred package manager:
# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex
Then simply run codex to get started.
You can also go to the latest GitHub Release and download the appropriate binary for your platform.
Each GitHub Release contains many executables, but in practice, you likely want one of these:
- macOS
- Apple Silicon/arm64:
codex-aarch64-apple-darwin.tar.gz - x86_64 (older Mac hardware):
codex-x86_64-apple-darwin.tar.gz
- Apple Silicon/arm64:
- Linux
- x86_64:
codex-x86_64-unknown-linux-musl.tar.gz - arm64:
codex-aarch64-unknown-linux-musl.tar.gz
- x86_64:
Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
