OpenAI has released a paper highlighting the transformative impact of its Codex AI, which now generates 99.8% of the company’s internal output tokens and is expanding its usage beyond technical roles into areas such as Legal, Finance, Recruiting, and Support. This shift follows a staggering rise in non-developer adoption rates, with individual use increasing 137 times and organizational use increasing 189 times since August 2025. The report indicates that users are increasingly managing multiple agents for parallel task execution, reshaping traditional work units as they supervise fleets of agents to streamline processes across various business functions.

Codex: Codex is OpenAI’s AI model and agent system that originated as a coding tool but has expanded to support a wide range of office tasks. In the released paper, Codex now accounts for the vast majority of internal output tokens at OpenAI and is driving rapid non-developer adoption both inside the company and among external organizations.
OpenAI: OpenAI is an AI research and deployment company that develops advanced models and agentic tools for various applications. The company recently released a paper highlighting how its internal teams across departments are using Codex agents to handle complex, longer-running, and cross-functional work under human supervision.

Agent Expansion: Agent capabilities are moving beyond technical teams into areas with repeatable processes, rules, and follow-through requirements, enabling organizations to test real-world workplace changes before wider availability.
Workplace Transformation: AI companies are using their own agentic tools internally to demonstrate how fleets of agents can shift work from individual interactions to supervised, parallel task execution across business functions.
