OpenAI updated Codex with GPT-5.6 Sol and a new Ultra mode, expanded Computer Use with appshots, added Browser Use with inline editing, and shipped Sites for direct publishing. The update also introduces parallel work coordination across projects and pull request review workflows. Codex on mobile is now available.
The mechanics matter here. Appshots give Computer Use a structured way to capture and replay UI state. Inline editing lets Codex modify code and documents in context without round-tripping to a separate interface. PR review integration means Codex can participate in the actual merge workflow, not just generate code and stop.
The video teases something unreleased at the end, which is the real reason to watch the full runtime. OpenAI Build Week gets its own segment at 06:35, signaling a developer-focused push beyond the feature list. The coordination layer for parallel projects is the least-covered but potentially most consequential addition for teams running multiple Codex agents simultaneously.
