## Summary This fixes a TUI race (https://github.com/openai/codex/issues/11008) where pressing Enter with Steer enabled while the assistant is still streaming the final answer could put Codex into a non-recoverable “running” state (no further prompts handled until exiting and resuming). ## Root Cause In steer mode, `InputResult::Submitted` could submit immediately even while a final-answer stream was active. That immediate submission races with turn completion and can strand turn state. ## Fix When handling `InputResult::Submitted`, we now queue instead of immediate-submit if a final-answer stream is active (`stream_controller.is_some()`). This keeps behavior deterministic: - Prompt is preserved in the queue. - `on_task_complete()` drains queued input through `maybe_send_next_queued_input()`. - Follow-up prompts continue in FIFO order after completion. ## Why this resolves the “dead mode” The problematic timing window is now converted into queueing, so prompts entered during final streaming are not lost and are processed after the current output ends. The model continues handling prompts normally without requiring `/quit` + `resume`. ## Tests Added regression coverage in `tui/src/chatwidget/tests.rs`: - `steer_enter_queues_while_final_answer_stream_is_active` - `steer_enter_during_final_stream_preserves_follow_up_prompts_in_order` Both fail on old behavior and pass with this fix.
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.
