## What - make Fjord's centralized response-item image preparation unconditional for new and resumed history - have local user images and `view_image` outputs always defer decoding and resizing to that path - retain `resize_all_images` as an ignored, removed compatibility key for released clients - delete the flag-off producer paths and obsolete policy-specific tests ## Why Centralized preparation is now the intended image path. Keeping the runtime feature checks also kept two image-processing implementations alive and allowed client config to select the legacy behavior. This is a clean replacement for #28975, rebuilt from the latest `main`. ## How `prepare_response_items` now runs whenever items enter history and whenever persisted history is reconstructed. Producers emit deferred image data, so malformed images become the existing model-visible placeholder instead of failing the session at the producer. ## Test plan - `just fmt` - `just fix -p codex-core -p codex-features` - `just test -p codex-features` — 52 passed - focused affected `codex-core` set — 20 passed - `just test -p codex-core handle_accepts_explicit_high_detail` — 1 passed - full `just test -p codex-core` attempt — 2,723 passed; 88 unrelated environment failures from read-only `~/.codex` SQLite state and unavailable integration helper binaries
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.
