## Why `prewarm_websocket` intentionally stays out of rollout inference tracing, but the next traced websocket request can still reuse the warmup `response_id` and send an empty `input` delta. If tracing records that wire payload verbatim, replay sees an incremental request whose parent was never traced and cannot reconstruct the conversation. This fixes that at the producer boundary instead of relaxing `rollout-trace` replay semantics around unresolved `previous_response_id` values. ## What - track whether the last websocket response came from an untraced warmup and clear that state when the websocket session is reset or reconnected - when a traced websocket request reuses that warmup parent, keep sending the compressed websocket request on the wire but record the logical `ResponsesApiRequest` in the rollout trace - add a regression test that proves replay reconstructs the logical user message even though the websocket follow-up carries `previous_response_id = warm-1` with empty `input` - update `InferenceTraceAttempt::record_started` docs to reflect that callers may record a logical request rather than the exact transport payload ## Testing - `cargo test -p codex-core --test all responses_websocket_request_prewarm_traces_logical_request`
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.
