## Why `ModelClientSession` and `compact_conversation_history()` were still rebuilding the same `ResponsesApiRequest` fields separately. That duplication makes it easy for normal `/responses` turns and compact requests to drift when request-shape changes land later, which is exactly the kind of cache-affecting divergence we want to avoid. This follow-up keeps the scope small by extracting the shared request-construction logic into one helper and using it from both paths. ## What changed - move `ResponsesApiRequest` construction into a shared `ModelClient::build_responses_request(...)` helper in `core/src/client.rs` - update the normal `/responses` streaming path to call that helper instead of the old `ModelClientSession`-local implementation - update `compact_conversation_history()` to derive its compact payload from the same helper so `model`, `instructions`, `input`, `tools`, `parallel_tool_calls`, `reasoning`, and `text` stay aligned with normal request building - add a unit test covering the shared helper's prompt cache key, installation metadata, and `service_tier` behavior ## Verification - `cargo test -p codex-core build_responses_request_sets_shared_cache_and_metadata_fields` - `cargo test -p codex-core --test all remote_compact_v2_reuses_context_compaction_for_followups` ## Docs No docs update needed.

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.
