- MCP tools now use tool search by default when supported, improving tool discovery while preserving compatibility with older models and providers. (#29486) - macOS authentication clients can honor system proxy, PAC, and WPAD settings when `respect_system_proxy` is enabled. (#26709) - Plugins can provide dedicated dark-mode logos through local manifests and remote catalogs. (#29488) - Apps can display richer safety-buffering UI using server-provided visibility and faster-model metadata. (#29473) ## Bug Fixes - Remote plugin catalogs now return curated featured-plugin rankings. (#29485) - Expired Amazon Bedrock credentials now produce actionable recovery guidance instead of a generic authorization error. (#28992) - Remote stdio MCP servers now accept absolute working directories written in the remote platform’s path format. (#29493) - Remote HTTP(S) image inputs now return clear model-visible validation errors; inline data URLs and local images remain supported. (#29417, #29419) - PowerShell commands containing executable AST regions the safety classifier cannot inspect now require approval. (#24092) - Code Mode now warns when the selected model lacks the required metadata. (#29490) ## Chores - Updated bundled OpenSSL and esbuild dependencies to patched releases. (#29487, #29489) - Successful formatter runs are now quiet while failures still show diagnostics.

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.
