## Why The Bedrock GPT-5.6 catalog advertises `max`, but Codex treated it as an opaque custom effort. That made the reasoning picker render it as lowercase `max` while known efforts use productized labels. Making `max` a known effort aligns catalog data, parsing, and UI presentation without changing the `max` wire value or persisted representation. ## What changed - Add first-class `ReasoningEffort::Max` parsing and serialization. - Use the typed effort in the Bedrock catalog and render it as `Max` in the TUI. - Preserve forward-compatible custom-effort coverage with a genuinely unknown `future` value. ### Before <img width="559" height="124" alt="Screenshot 2026-06-28 at 12 08 47 PM" src="https://github.com/user-attachments/assets/7c43cf4f-020b-4605-9239-0a9c97eb7364" /> ### After <img width="558" height="107" alt="Screenshot 2026-06-28 at 12 09 10 PM" src="https://github.com/user-attachments/assets/b9cc5ded-c940-43b4-b024-bba25abe0a17" />
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.
