## What This PR defines the structured configuration contract for shared rollout token budgets (across ALL agent threads under 1 rollout). ```toml [features.rollout_budget] enabled = true limit_tokens = 100000 reminder_interval_tokens = 10000 sampling_token_weight = 1.0 prefill_token_weight = 0.1 ``` The reminder interval defaults to 10% of the rollout limit. Sampling and prefill weights default to `1.0`. ## Scope This PR only defines and validates configuration. It does not track usage, inject reminders, or stop a rollout. Accounting and reminders are implemented in the stacked follow-up #28494. The existing `token_budget` feature remains unchanged. `rollout_budget` has its own feature key and configuration type. ## Tests The config test verifies that the structured fields resolve into `RolloutBudgetConfig` and do not enable the existing `token_budget` feature. Local checks: - `just write-config-schema` - `just test -p codex-core load_config_resolves_rollout_budget` - `cargo check -p codex-thread-manager-sample` - `git diff --check` The full workspace test suite was not run locally.
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.
