OpenAI Codex Gets Sites, Annotations, and Enterprise Workspaces

OpenAI Codex — What's New in June 2026?

OpenAI just rolled out a massive Codex update: domain-specific workflows, a semi-private web hosting feature called "Sites," and an in-place editing tool named "Annotations." The goal? Transform Codex from a developer tool into an everyday business operating system.

Why Are Non-Developers Using Codex?

Here's the surprise: non-developers now make up roughly 20% of Codex's 5 million weekly users. Financial analysts, marketers, operators, and researchers are adopting the platform three times faster than traditional engineers. OpenAI is clearly targeting this white-collar automation opportunity.

What Are Annotations and Why Do They Matter?

Previously, asking an AI to update a chart or spreadsheet often meant rewriting the entire file — which broke formatting and introduced errors. Annotations solves this by mapping a document's data schema and applying localized edits. You highlight what you want changed, and Codex edits only that section. No more full-document regeneration.

How Does Sites Work?

Sites is Codex's new semi-private web hosting feature. AI agents can build and deploy interactive web workspaces that teams can access without leaving the Codex environment. Think internal dashboards, project trackers, or client portals — all generated and maintained by AI.

Common Questions (FAQ)

Q: Is Codex free to use? A: Codex is available through OpenAI's paid plans. The new Sites and Annotations features are rolling out to Pro and Enterprise tiers first.

Q: Can Annotations work with Excel files? A: Yes. Annotations maps the underlying data schema of spreadsheets and makes localized edits without regenerating the entire document.

Q: How is this different from Microsoft Copilot? A: Codex focuses on autonomous agent-driven workflows, while Copilot is more of an in-app assistant. Codex Agents can build entire workspaces and deploy them via Sites.
