Less than two weeks after its July 9th launch, OpenAI announced that ChatGPT Work and Codex have reached a combined 10 million monthly active users. This milestone reflects an explosion in usage, with Codex's MAU increasing more than 10x from January 2026.
- The product expansion marks a shift from coding agents to knowledge work agents, with knowledge workers now accounting for roughly 20% of Codex's user base and growing 3x faster than developers.
- ChatGPT Work enables users to collaborate with agents across various primitives like documents, spreadsheets, and slide decks by describing outcomes rather than manually operating applications.
- The platform shares a common agent harness with Codex but differs in UX, Git visibility, artifacts, and sandboxing defaults to suit non-engineers.
- OpenAI consolidated its product teams under leaders Greg Brockman and Tibo to complete a "Superapp" consolidation cycle, merging agent experiences rather than building separate products.
The integration allows users to delegate tasks across code, Slack, documents, and local files, aiming to make the power of software accessible to people who do not write code.
