## Why Spawned agents can already override `model` and `reasoning_effort`, but they have no equivalent way to opt into a model-supported service tier. That makes it impossible to preserve or intentionally select tiered execution behavior when delegating work to a sub-agent, even though the model catalog already advertises supported `service_tiers`. ## What changed - Add optional `service_tier` to both legacy and `MultiAgentV2` `spawn_agent` tool inputs. - Show each picker-visible model's supported service tier ids and descriptions in the `spawn_agent` tool guidance. - Resolve service tier selection after the child agent's effective model is known. - Inherit the parent tier when omitted and still supported by the final child model; otherwise clear it. - Reject explicit unsupported tier requests with a model-facing error. - Keep explicit `service_tier` usable on full-history forks, while still honoring the existing model/reasoning fork restrictions. - Hide `service_tier` alongside other spawn metadata when `hide_spawn_agent_metadata` is enabled. ## Verification Added focused coverage for: - v1/v2 `spawn_agent` schema exposure for `service_tier` - tier descriptions in spawn guidance - hidden-metadata suppression - explicit supported tier selection - explicit unknown and unsupported tier rejection - inherited tier preservation or clearing based on child-model support - full-history fork acceptance for explicit service tiers in both v1 and v2 Local Rust tests were not run in this workspace per repo guidance; the new coverage is included for CI.
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.
