OpenAI Codex Hits 3 Million Weekly Users, Processing 15 Billion Tokens Per Minute

OpenAI's dedicated coding AI engine, Codex, has reached a new milestone of 3 million weekly active users. Processing over 15 billion tokens per minute, it has cemented its position as the de facto standard for autonomous software engineering.

Codex is known as the foundation technology behind GitHub Copilot, but the latest version goes far beyond code completion — it can automatically fix bugs, generate tests, perform code reviews, and even suggest architecture decisions. Research suggests it improves developer productivity by an average of 40-60%.

Despite rising competition from Cursor, Devin, and Amazon CodeWhisperer, Codex maintains its lead through integration with OpenAI's large-scale models, rich contextual understanding, and a deep developer ecosystem. As software development automation advances, 'programmers who collaborate with AI' is becoming the new standard, with Codex at the center of this transformation.
