- API v2 threads can now inject dynamic tools at startup and route their calls/responses end-to-end through the server and core tool pipeline. (#9539) - Added filtering on the thread list in the app server to make large thread sets easier to browse. (#9897) - Introduced a `thread/unarchive` RPC to restore archived rollouts back into active sessions. (#9843) - MCP servers can now define OAuth scopes in `config.toml`, reducing the need to pass `--scopes` on each login. (#9647) - Multi-agent collaboration is more capable and safer, with an explorer role, better collab event mapping, and max-depth guardrails. (#9817, #9818, #9918, #9899) - Cached `web_search` is now the default client behavior. (#9974) ## Bug Fixes - Fixed a TUI deadlock/freeze under high streaming throughput by avoiding blocking sends on the main Tokio thread. (#9951) - The `web_search` tool now handles and displays all action types, and shows in-progress activity instead of appearing stuck. (#9960) - Reduced high CPU usage in collaboration flows by eliminating busy-waiting on subagents. (#9776) - Fixed `codex resume --last --json` so prompts parse correctly without conflicting argument errors. (#9475) - Windows sandbox logging now handles UTF-8 safely, preventing failures when truncating multibyte content. (#8647) - `request_user_input` is now rejected outside Plan/Pair modes to prevent invalid tool calls. (#9955) ## Documentation - Updated the contribution guidelines for clearer onboarding and workflow expectations. (#9933) - Refreshed protocol/MCP docs to reflect `thread/unarchive` and the updated `request_user_input` question shape. (#9843, #9890) ## Chores - Self-update via Homebrew now uses an explicit cask upgrade command to avoid warnings and ambiguity. (#9823) - Release packaging now consistently writes the bundle zip to `dist/`. (#9934) - Updated key dependencies in the Rust workspace (including `axum`, `tracing`, `globset`, and `tokio-test`). (#9880, #9882, #9883, #9884) - Aligned feature stage naming with public maturity stages and added clearer warnings for underdevelopment features. (#9929, #9954) ## Changelog Full Changelog: https://github.com/openai/codex/compare/rust-v0.91.0...rust-v0.92.0 - #9850 chore: remove extra newline in println @SohailRaoufi - #9868 Adjust modes masks @aibrahim-oai - #9874 Prompt @aibrahim-oai - #9877 Plan prompt @aibrahim-oai - #9718 feat(tui) /personality @dylan-hurd-oai - #9871 chore(core) move model_instructions_template config @dylan-hurd-oai - #9539 feat: dynamic tools injection @jif-oai - #9818 feat: rebase multi-agent tui on `config_snapshot` @jif-oai - #9789 Fix flakey resume test @gt-oai - #9784 Fix flakey conversation flow test @gt-oai - #9918 feat: explorer collab @jif-oai - #9899 feat: disable collab at max depth @jif-oai - #9916 Fix up config disabled err msg @gt-oai - #9890 Feat: add isOther to question returned by request user input tool @shijie-oai - #9817 feat: codex exec mapping of collab tools @jif-oai - #9919 Fix flakey shell snapshot test @gt-oai - #9776 fix: attempt to reduce high cpu usage when using collab @eugeneoden - #9928 prompt @aibrahim-oai - #9925 chore: update interrupt message @jif-oai - #9843 Add thread/unarchive to restore archived rollouts @charley-oai - #9929 Aligned feature stage names with public feature maturity stages @etraut-openai - #9934 ensure codex bundle zip is created in dist/ @iceweasel-oai - #9897 [app-server] feat: add filtering on thread list @jif-oai - #9647 Add MCP server `scopes` config and use it as fallback for OAuth login @blevy-oai - #9943 plan prompt @aibrahim-oai - #8647 fix: handle utf-8 in windows sandbox logs @davidgilbertson - #9891 Add composer config and shared menu surface helpers @aibrahim-oai - #9880 chore(deps): bump tracing from 0.1.43 to 0.1.44 in /codex-rs @dependabot - #9882 chore(deps): bump tokio-test from 0.4.4 to 0.4.5 in /codex-rs @dependabot - #9883 chore(deps): bump axum from 0.8.4 to 0.8.8 in /codex-rs @dependabot - #9884 chore(deps): bump globset from 0.4.16 to 0.4.18 in /codex-rs @dependabot - #9901 fix: remove cli tooltip references to custom prompts @mattridley - #9823 fix: use `brew upgrade --cask codex` to avoid warnings and ambiguity @JBallin - #9951 fix: try to fix freezes 2 @jif-oai - #9955 Reject request_user_input outside Plan/Pair @charley-oai - #9933 Updated contribution guidelines @etraut-openai - #9892 Reuse ChatComposer in request_user_input overlay @aibrahim-oai - #9957 NIT larger buffer @jif-oai - #9953 feat: load interface metadata from SKILL.json @alexsong-oai - #9954 Warn users on enabling underdevelopment features @aibrahim-oai - #9961 Use test_codex more @pakrym-oai - #9960 fix: handle all web_search actions and in progress invocations @sayan-oai - #9966 plan prompt v7 @aibrahim-oai - #9968 Improve plan mode prompt @aibrahim-oai - #9969 prompt final @aibrahim-oai - #9475 Fix `resume --last` with `--json` option @etraut-openai - #9970 prompt @aibrahim-oai - #9975 plan prompt @aibrahim-oai - #9974 make cached web_search client-side default @sayan-oai - #9971 tui: wrapping user input questions @aibrahim-oai - #9977 make plan prompt less detailed @aibrahim-oai - #9980 Fixing main and make plan mode reasoning effort medium @aibrahim-oai - #9759 Fix: cap aggregated exec output consistently @Kbediako
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 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.
