- TUI markdown now keeps web links clickable with OSC 8 metadata, and cramped tables switch to readable key/value records without losing link targets. (#24472, #24636, #24825) - Sessions can now be archived from the TUI with `/archive` or from the CLI with `codex archive` / `codex unarchive`; archived sessions are protected from resume/fork until restored. (#25027, #25021) - App-server integrations can resume a thread with its initial turns page, see richer MCP server status, and launch stdio mode with `codex app-server --stdio`. (#23534, #24698, #24940) - Remote execution setup now supports `CODEX_API_KEY` registration for approved OpenAI hosts, while remote-control websockets use short-lived server tokens instead of ChatGPT access tokens. (#24666, #24141) - Windows admins get an alpha `codex sandbox setup --elevated` provisioning path, plus requirements support for allowed Windows sandbox implementations. (#24831, #23766) - A feature-gated standalone image generation extension can run through the native Codex image artifact completion pipeline. (#24723, #24972) ## Bug Fixes - ChatGPT auth refreshes tokens before the five-minute expiry window and shows a relogin-required path for reused refresh tokens instead of collapsing into a generic cloud error. (#23546, #24830) - Command-safety hardening prevents `/diff` from running repository-provided Git helpers/hooks, avoids PowerShell parser execution on non-Windows hosts, and rejects browser-origin exec-server websocket handshakes. (#24954, #24946, #24947) - Sandboxed commands clean up more reliably after interruptions or denied Windows network attempts, and `deny` read rules stay enforced for safe-command and approval-bypass paths. (#22729, #19880, #23943) - Resumed TUI sessions seed prompt history from the session transcript, multiline hook output renders as separate rows, and Vim normal-mode editing behaves correctly. (#24298, #24965, #25022) - App-server filesystem watchers debounce later batches correctly, and standalone web search calls now show and restore completed search activity. (#24716, #24693) - Bedrock auth now falls back to `AWS_REGION` / `AWS_DEFAULT_REGION`, and unsupported Bedrock GPT service tiers are no longer advertised or sent. (#25171, #25318) ## Documentation - Python SDK beta docs and package metadata now present the standard `pip install openai-codex` path, refreshed quickstarts, API reference, FAQ, and examples. (#24836, #24866, #24868, #24870) - Python SDK examples and docs now use the public `CodexConfig` name for configuring `Codex` / `AsyncCodex`. (#24800) - The bundled OpenAI Docs skill was updated with current Codex manual routing and a cached manual fetch helper. (#24914) - Built-in tool schema descriptions now clarify defaults, optional fields, bounds, and enums across shell, Code Mode, MCP, image, goal, plan, multi-agent, and related tools. (#24794) - App-server and exec-server docs now cover API-key remote registration, `--stdio`, runtime extra skill roots, and remote-control server-token behavior. (#24666, #24940, #24977, #24141) ## Chores - Python SDK releases can now be staged and published independently from runtime releases using `python-v*` tags while preserving the reviewed runtime dependency pin. (#24828, #24872) - Updated MCP dependencies to `rmcp` 1.7.0 and refreshed compatibility code. (#24763) - Refreshed Amazon Bedrock catalog metadata, including GPT-5.5, removal of unsupported OSS entries, and default-tier-only GPT model behavior. (#24701, #24960, #25318) - Removed the stale app-server debug-client pieces and cleaned up the workspace after deletion. (#25063, #25064, #25065, #25066, #25067, #25068, #25069, #25070, #25075) - Trimmed CI/build maintenance by moving Bazel Windows jobs to Codex runners, removing the libubsan workaround, and reverting the startup benchmark that broke musl builders. (#24952, #24782, #24937) ## Changelog Full Changelog: https://github.com/openai/codex/compare/rust-v0.135.0...rust-v0.136.0 - #22729 fix(linux-sandbox): preserve shell cleanup on interruption @viyatb-oai -

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.
Using Codex with your ChatGPT plan
Run codex and select Sign in with ChatGPT. We recommend signing into your ChatGPT account to use Codex as part of your Plus, Pro, Business, Edu, or Enterprise plan. Learn more about what's included in your ChatGPT plan.
You can also use Codex with an API key, but this requires additional setup.
