## Why Token activity is useful account-level context, but terminal clients need a supported app-server path to fetch it without reaching into ChatGPT backend details directly. The API should also live under the broader account usage umbrella so future usage surfaces can be added without proliferating user-facing concepts. ## What Changed - Add `codex-backend-client` support for the ChatGPT profile token-usage payload. - Add the v2 `account/usage/read` app-server RPC. - Map lifetime usage, peak daily usage, streak, longest task duration, and daily buckets into app-server protocol types. - Gate the request on Codex-backend auth, which supports ChatGPT auth tokens and AgentIdentity. - Regenerate the app-server JSON and TypeScript schema fixtures. ## Token Count Source `account/usage/read` returns the token-usage aggregate supplied by the ChatGPT profile backend. App-server maps that backend-owned aggregate into protocol fields; it does not recompute cached-token treatment, usage multipliers, or raw input/output totals locally. ## Stack 1. feat(app-server): expose account token usage [1 of 2] (this PR) 2. [#25345](https://github.com/openai/codex/pull/25345) feat(tui): add token activity command [2 of 2] ## How to Test 1. Start an app-server client from this branch while authenticated with ChatGPT or AgentIdentity. 2. Call `account/usage/read`. 3. Confirm the response includes `summary` and `dailyUsageBuckets`. 4. Also verify a session without Codex-backend auth receives the existing auth error path. Targeted tests: - `just test -p codex-backend-client -p codex-app-server-protocol -p codex-app-server` - `just write-app-server-schema`
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
Run the following on Mac or Linux to install Codex CLI:
curl -fsSL https://chatgpt.com/codex/install.sh | sh
Run the following on Windows to install Codex CLI:
powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"
Codex CLI can also be installed via the following package managers:
# 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.
Using Codex with your ChatGPT plan
Run codex and select Sign in with ChatGPT. We recommend signing into your ChatGPT account to use Codex as part of your Plus, Pro, Business, Edu, or Enterprise plan. Learn more about what's included in your ChatGPT plan.
You can also use Codex with an API key, but this requires additional setup.
