## Why Codex needs a first-class `amazon-bedrock` model provider so users can select Bedrock without copying a full provider definition into `config.toml`. The provider has Codex-owned defaults for the pieces that should stay consistent across users: the display `name`, Bedrock `base_url`, and `wire_api`. At the same time, users still need a way to choose the AWS credential profile used by their local environment. This change makes `amazon-bedrock` a partially modifiable built-in provider: code owns the provider identity and endpoint defaults, while user config can set `model_providers.amazon-bedrock.aws.profile`. For example: ```toml model_provider = "amazon-bedrock" [model_providers.amazon-bedrock.aws] profile = "codex-bedrock" ``` ## What Changed - Added `amazon-bedrock` to the built-in model provider map with: - `name = "Amazon Bedrock"` - `base_url = "https://bedrock-mantle.us-east-1.api.aws/v1"` - `wire_api = "responses"` - Added AWS provider auth config with a profile-only shape: `model_providers.<id>.aws.profile`. - Kept AWS auth config restricted to `amazon-bedrock`; custom providers that set `aws` are rejected. - Allowed `model_providers.amazon-bedrock` through reserved-provider validation so it can act as a partial override. - During config loading, only `aws.profile` is copied from the user-provided `amazon-bedrock` entry onto the built-in provider. Other Bedrock provider fields remain hard-coded by the built-in definition. - Updated the generated config schema for the new provider AWS profile config.
npm i -g @openai/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.
