## Why Memory startup was tied to thread lifecycle events such as create, load, and fork. That can run memory work before a thread receives real user input, and it makes startup cost scale with thread management instead of actual turns. Moving the trigger to `thread/sendInput` keeps memory startup aligned with the first real user turn and lets it use the current thread config at turn time. The idea is to prevent ghost cost due to pre-warm triggered by the app Turn-based startup can also make global phase-2 consolidation easier to request repeatedly, so this adds a success cooldown and tightens the default startup scan window. ## What Changed - Start `codex_memories_write::start_memories_startup_task` after a non-empty `thread/sendInput` turn is submitted, instead of from thread create/load/fork paths: https://github.com/openai/codex/blob/d4a6885b7829e2fd2ec7a09355e4f75ebe1d1fe3/codex-rs/app-server/src/codex_message_processor.rs#L6477-L6487 - Expose `CodexThread::config()` so app-server can pass the live config into memory startup at turn time. - Add a six-hour successful-run cooldown for global phase-2 consolidation via `SkippedCooldown`: https://github.com/openai/codex/blob/d4a6885b7829e2fd2ec7a09355e4f75ebe1d1fe3/codex-rs/state/src/runtime/memories.rs#L963-L966 - Reduce memory startup defaults to at most 2 rollouts over 10 days: https://github.com/openai/codex/blob/d4a6885b7829e2fd2ec7a09355e4f75ebe1d1fe3/codex-rs/config/src/types.rs#L31-L34 ## Verification Updated the memory runtime coverage around phase-2 reclaim behavior, including `phase2_global_lock_respects_success_cooldown`. --------- Co-authored-by: Codex <noreply@openai.com>

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.
