OpenAI’s push into agentic AI, the kind that doesn’t just answer questions but actually does things across your apps, has crossed the 10 million user mark. The milestone comes on the heels of ChatGPT Work’s launch on July 9, 2026, which positioned OpenAI squarely in the territory of enterprise workflow automation.
ChatGPT Work functions as an agent that pulls context from multiple applications to handle multi-step tasks.
From Codex to ChatGPT Work: the adoption ramp
At launch, ChatGPT Work inherited more than 5 million weekly users from Codex, OpenAI’s coding-focused tool, plus over 1 million non-development users who were already leaning on the platform for tasks beyond writing code.
By November 2025, ChatGPT for Work had exceeded 7 million seats. That represented a 40% increase in just two months.
