## Summary Fixes #11678 by removing the Windows-specific `PASTE_BURST_CHAR_INTERVAL` override. Windows now uses the same `8ms` paste-burst character interval as macOS and Linux, which removes the extra per-character hold that made fast typing and key repeat feel delayed on Windows. The paste-burst heuristic itself is unchanged, and the Windows-specific active idle timeout remains in place. This PR only restores the shared character-to-character burst threshold that decides whether adjacent plain character events are part of a paste. ## Motivation PR #9348 raised the Windows character interval from `8ms` to `30ms` to protect the multiline paste behavior tracked in #2137, where pasted newlines could be interpreted as submits in Windows terminals. That fixed the paste failure, but it also made ordinary typing visibly laggy because the TUI waits briefly before flushing a single typed character while it checks whether a paste burst is forming. The deployed behavior here is to remove that Windows-only delay and return to the cross-platform threshold. Manual Windows validation of the critical VS Code integrated terminal path shows multiline paste still works with the final `8ms` value, including testing on VS Code `1.107.0`. ## Testing - `cargo test -p codex-tui` - Manual Windows validation in VS Code integrated PowerShell with the final `8ms` interval
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 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.
