## Why The realtime frontend model and the backing Codex thread should present one coherent assistant. Raw typed messages, steers, and worker reports belong to the orchestrator; the frontend model should receive the orchestrator's user-facing result rather than a second copy of those inputs. Today normal `turn/start` input is automatically inserted into the realtime conversation, while `turn/steer` is not. Besides creating inconsistent context, this can make the frontend model react independently before Codex has produced the response it should speak. ## What changed - Remove automatic accepted-user-input mirroring into realtime - Remove the mirror-only echo-suppression flag and dead V2 prefix helper - Preserve explicit app-to-realtime text injection and FEM-to-Codex delegation - Replace the positive mirror tests and obsolete snapshots with a negative routing regression test ## Test plan - `cargo test -p codex-core conversation_user_text_turn_is_not_sent_to_realtime` - `cargo test -p codex-core conversation_startup_context_is_truncated_and_sent_once_per_start` - `cargo test -p codex-core inbound_handoff_request_starts_turn`
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.
