## Why The TUI can run against a remote app server, but several high-traffic settings still persisted by editing the local config file. That sends remote sessions' preference writes to the wrong machine and lets local disk state drift from the app-server-owned config. This is **[1 of 4]** in a stacked series that moves TUI-owned config mutations onto app-server APIs. ## What changed - Added a small TUI helper for typed app-server config writes. - Routed primary interactive preference writes through `config/batchWrite`. - Preserved existing profile scoping for settings that already support `profiles.<profile>.*` overrides. ## Config keys affected - `model` - `model_reasoning_effort` - `personality` - `service_tier` - `plan_mode_reasoning_effort` - `approvals_reviewer` - `notice.fast_default_opt_out` - Profile-scoped equivalents under `profiles.<profile>.*` ## Suggested manual validation - Connect the TUI to a remote app server, change `model` and `model_reasoning_effort`, reconnect, and confirm the remote config retained both values while the local `config.toml` did not change. - Change `personality`, `plan_mode_reasoning_effort`, and the explicit auto-review selection, then reconnect and confirm those choices persist through the app server. - Clear the service tier back to default and confirm `service_tier` is cleared while `notice.fast_default_opt_out = true` is persisted remotely. - Repeat one setting change with an active profile and confirm the write lands under `profiles.<profile>.*`. ## Stack 1. [#22913](https://github.com/openai/codex/pull/22913) `[1 of 4]` primary settings writes 2. [#22914](https://github.com/openai/codex/pull/22914) `[2 of 4]` app and skill enablement 3. [#22915](https://github.com/openai/codex/pull/22915) `[3 of 4]` feature and memory toggles 4. [#22916](https://github.com/openai/codex/pull/22916) `[4 of 4]` startup and onboarding bookkeeping
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.
