## Why Remote compaction v2 is the `/responses` implementation of session-history compaction, but it still needs to preserve the observable contract of the legacy `/responses/compact` path. In particular, users and integrations that rely on `PreCompact` and `PostCompact` hooks should not see different behavior when `remote_compaction_v2` is enabled. ## What Changed - Runs `PreCompact` before issuing the remote compaction v2 request, including `Interrupted` analytics when a pre-hook stops execution. - Runs `PostCompact` after a successful v2 compaction and aborts the turn if the post-hook stops execution. - Adds `compact_remote_parity` coverage that compares legacy and v2 compaction across manual transcript shapes, automatic pre-turn compaction, automatic mid-turn compaction, hook payloads, replacement history, follow-up request payloads, and API-key `service_tier=fast` behavior. - Registers the new parity suite under `core/tests/suite`. Relevant code: - [`compact_remote_v2.rs`](https://github.com/openai/codex/blob/af63745cb502183a6fc447d0240f8150934d70b7/codex-rs/core/src/compact_remote_v2.rs) - [`compact_remote_parity.rs`](https://github.com/openai/codex/blob/af63745cb502183a6fc447d0240f8150934d70b7/codex-rs/core/tests/suite/compact_remote_parity.rs) ## Verification - Added `core/tests/suite/compact_remote_parity.rs` to assert parity between legacy remote compaction and remote compaction v2 for the affected request, hook, rollout-history, and follow-up paths. - Existing `compact_remote_v2` unit coverage still exercises v2 replacement-history retention and compaction-output collection.

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.
