OpenAI Codex hits 3M weekly users

OpenAI said on April 8 that Codex had reached 3 million weekly active users, tying the milestone to a wider push to sell more AI tools into large companies. (openai.com) The number appeared in a note from Chief Revenue Officer Denise Dresser, who said enterprise now makes up more than 40% of OpenAI revenue and could reach parity with consumer by the end of 2026. (openai.com) Codex is OpenAI’s coding agent: software that can read a codebase, run commands, draft changes, review pull requests, and work across tools instead of only answering chat prompts. (openai.com) On April 16, OpenAI expanded that pitch with a major Codex update for macOS and Windows, adding computer use, browser access, image generation, memory, and automations. (openai.com) OpenAI said Codex can now “see,” click, and type on a user’s computer with its own cursor, while multiple agents run in parallel without interrupting the person using the machine. (openai.com) The same release added more than 90 plugins, including integrations for Atlassian Rovo, CircleCI, CodeRabbit, GitLab Issues, Microsoft Suite, Neon by Databricks, Render, and Superpowers. (openai.com) For developers working off remote machines, OpenAI also published SSH support in alpha. The company said Codex can attach to projects on another SSH-accessible host and run threads against that remote filesystem and shell. (developers.openai.com) OpenAI’s product pages now describe Codex as a “command center” for multi-agent coding, with built-in worktrees, cloud environments, and always-on automations for tasks like issue triage, alert monitoring, and continuous integration pipelines. (openai.com) The growth number moved again almost immediately. On April 21, OpenAI said Codex had grown from more than 3 million weekly developers in early April to more than 4 million just two weeks later. (openai.com) That April 21 post also showed where OpenAI wants Codex used next: Virgin Atlantic for test coverage, Ramp for code review, Notion for feature work, Cisco for large repositories, and Rakuten for incident response. (openai.com) To speed that rollout, OpenAI launched Codex Labs and said Accenture, Capgemini, CGI, Cognizant, Infosys, PwC, and Tata Consultancy Services would help deploy Codex inside large engineering organizations. (openai.com) The 3 million figure is real, but it was already out of date within days. OpenAI’s own timeline shows Codex moving from a coding assistant milestone into a broader enterprise software push in April 2026. (openai.com 1) (openai.com 2)
