OpenAI Codex Expands: Sites, Annotations, Plugins Unveiled

OpenAI has expanded its Codex with new features, including Sites, Annotations, and plugins. This update adds in-thread web tooling and a larger plugin ecosystem to ChatGPT Codex. The Codex in-app browser now supports browser comments for visual annotations. Users can also manage allowed and blocked websites from their settings. OpenAI Academy materials show Codex workflows can turn things like calendars and messages into review-ready briefs. What's more, there are broader platform additions, including gpt-image-1.5 and background Computer Use, which offers desktop control features. A plugin catalog is also available, with one report noting over 90 plugins and another describing a directory with more than a dozen prepackaged integrations. These changes move Codex from a coding assistant to a broader automation hub for knowledge workers. This means practitioners should evaluate the integration and trust implications.
