## Why Remote compaction now has two implementations: the existing server-rebuilt v1 path and the newer client-rebuilt v2 path behind `remote_compaction_v2`. The v1 path bounds retained user/developer/system history before installing the compaction item, while v2 was previously carrying the full retained history forward. That made the two paths diverge for large pre-compaction transcripts even though they are meant to preserve the same compaction contract. This aligns v2 with the retained-history budget expected from v1 so switching the feature flag does not materially change which pre-compaction messages survive into the rebuilt history. ## What changed - Apply a retained-message character budget while rebuilding v2 compacted history in `core/src/compact_remote_v2.rs`. - Keep newest retained messages first, truncate the boundary message with the shared `truncate_text(...)` helper, and drop older retained messages once the budget is exhausted. - Preserve non-text retained message content such as images while truncating text content. - Use the current `64_000` token retained-message default translated to the existing `4x` character budget. ## Testing - `cargo test -p codex-core compact_remote_v2::tests::` - Added focused coverage for newest-first retention and truncating multipart retained messages without dropping images.

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.
