Codex's desktop app now reviews code across every repo at once
Version 26.727 also lands multi-folder projects and a browser with YouTube Q&A, the week OpenAI shipped a Terraform provider and two transcription models.

Review the whole project, not one repo
The v26.727 desktop app now shows every repository in a multi-folder project and the exact lines changed in each, then lets you hit Review to read the diffs in one pane instead of hopping between repos. If your “project” is really three or four services, that's the entire review in one place.
Local projects can hold more than one folder
You now designate a primary folder — it anchors new chats, Git operations, and config-file discovery — while secondary folders stay fully searchable, readable, and editable. It's Codex finally matching how multi-service setups actually sit on disk.
The built-in browser got history and a YouTube brain
Codex's browser adds address-bar history and Google search, and the Chrome extension can now juggle your tabs and answer questions about a YouTube video you're watching. Pull one fact out of a 40-minute talk without scrubbing the timeline yourself.
Elsewhere: Terraform lands on the OpenAI API
OpenAI shipped an official Terraform provider (July 29) for managing API Platform resources as code — projects, keys, and settings in version control instead of a dashboard. If you spin up environments per team, this is your infra-as-code path.
Elsewhere: two new transcription models
Also new (July 28): GPT Transcribe for files and GPT Live Transcribe for low-latency streaming, both callable from the API plus Realtime turn transcripts. A drop-in upgrade if you're still on Whisper for captions or voice agents.
