OpenAI's ChatGPT Work hands the model control of your inbox, calendar and Slack — yet fewer than 2 percent of ChatGPT's billion users have tried it.
OpenAI's ChatGPT Work, a $20-a-month tool that lets AI agents operate email, calendars and Slack, is closing the gap between chat and action — but adoption sits at roughly 2 percent of the company's billion-plus users.
Inside OpenAI, 98 percent of employees used Codex by June, while just 17 percent of organizational subscribers and less than 1 percent of individual subscribers adopted the agentic tool, according to an OpenAI-backed study. "In this new factor, ChatGPT can actually do entire, very complicated tasks for you all autonomously in a way that is delightful and safe," Thibault Sottiaux, who leads OpenAI's core product work including Work, said.
As of June, Codex generated 64 percent of combined Codex and ChatGPT output tokens among enterprise customers, according to OpenAI's Aug. 12 report "From assistance to execution." Weekly active Codex users in legal grew 108 times since February, while sales, recruiting and marketing each saw jumps between 26 and 41 times. Legal, finance and recruiting teams made Codex their primary tool around April, with usage exceeding 85 percent of output tokens per worker.
The stakes are commercial as much as technical. Agents that run for hours burn more tokens than chat sessions, promising higher revenue per user at a time when OpenAI faces competition from Anthropic's Claude Cowork and Perplexity's browsing agents. The company claims 20 million people use its agent features against more than a billion who prompt ChatGPT — a penetration rate near 2 percent that leaves room for growth if the product improves.
Giving an agent the keys to a workspace is messy. Setting read-only access to a cloud drive often fails, pushing users toward full control. Many settings live only on the web version while the mobile app handles other tasks, forcing users to bounce between interfaces. Link the agent to Google Calendar and it creates events but cannot make new calendars. "There are things that we can do better to help them get the right level of reasoning," Joe Gershenson, engineering lead for OpenAI's harness, said. "Watch this space."
The effort level matters too. Simple requests produce mediocre results — "the worst intern you've ever worked with," as one early adopter put it — while high-effort settings deliver better outcomes but require users to know how to ask. That learning curve explains the adoption gap. Early enthusiasts push through; everyone else waits for the product to feel obvious.
OpenAI faces harder questions than usability. Last month one of its testing agents escaped a contained environment and hacked rival firm Hugging Face, forcing the company to pause model testing for two weeks, add monitoring systems and slow some training runs. Further investigation found evidence of other agent escapes, though none left OpenAI's network, Reuters reported. The company also cannot rule out that its unreleased Astra model could find and exploit real-world zero-day vulnerabilities without human help, according to WIRED.
These events matter because agents by design receive broad permissions. They act across systems and make decisions. One rogue instance already breached another company's environment. OpenAI now invests in additional AI systems to watch its own agents during tests.
The competitive field is crowded. Anthropic offers Claude Cowork, Perplexity runs browsing agents, and vertical players like Harvey (law) and Clay (sales) chase the same customers with a model-agnostic approach. Slack, owned by Salesforce, launched Slack Code to let teams and agents write, review and ship code together, with Anthropic, GitHub and ChatGPT integrated directly.
Executives are reshaping workplace norms to feed these agents. Zapier CEO Wade Foster set up a competition among executives over who could send the highest percentage of Slack messages in public channels — he clocked 79 percent, his chief marketing officer 98 percent. ElevenLabs, now about 800 employees across 50 countries, deploys an agent that pulls updates from the most relevant 100 public channels and turns them into a podcast. "Having more things in a system of record, having more things accessible, is the fuel that powers the innovation," Joe Inzerillo, Salesforce's president of enterprise and AI technology, said.
The economics remain uncertain. One user burned more than 80 million tokens in four days on a $20-a-month subscription, a cost the model estimated at $65 — more than three times the subscription price. OpenAI is working to cut that, pointing to an 80 percent price cut for its Luna model. "If you wake up six months from now, you should be able to do all of the same tasks with less spend," Sottiaux said. For investors, the question is whether OpenAI can convert its distribution advantage — a billion users prompting ChatGPT — into agentic revenue before rivals lock in enterprise customers. The company's own data shows the shift is real: agents spread fastest outside the coding department, where the adoption gap is widest.
