## Why `ModelClient` already carries the `HttpClientFactory` resolved from session configuration, but realtime call creation and memory summarization still constructed the legacy default client directly. Consequently, those first-party API requests could ignore `features.respect_system_proxy` even when Responses traffic honored it. These are the final direct default-client constructions in `core/src/client.rs`, so they form one small migration unit on top of #31361. ## What changed - Generalize `build_responses_transport` to `build_api_transport`. - Route realtime call creation through the helper using the selected provider and `/realtime/calls` destination. - Route `/memories/trace_summarize` through the same helper. - Remove the now-unused direct `build_reqwest_client` import. ## Review guide 1. The helper rename at the bottom of `core/src/client.rs` is mechanical and keeps existing Responses behavior unchanged. 2. The realtime call path computes the route from the final provider, including `api_provider_override`. 3. The memories path supplies its existing endpoint to the same API route class. ## Validation - `cargo check --tests -p codex-core` - `just fix -p codex-core` ## Follow-up Direct HTTP clients outside `ModelClient` remain separate migration slices. --- [//]: # (BEGIN SAPLING FOOTER) Stack created with [Sapling](https://sapling-scm.com).

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
Run the following on Mac or Linux to install Codex CLI:
curl -fsSL https://chatgpt.com/codex/install.sh | sh
Run the following on Windows to install Codex CLI:
powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"
Codex CLI can also be installed via the following package managers:
# 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.
