Latent Space: Codex and ChatGPT Work Hit 10 Million Users in Two Weeks, and Knowledge Workers Are Growing 3x Faster Than Developers
In a July 28 episode, OpenAI core product engineering lead Akshay Nathan says Codex and ChatGPT Work combined reached 10 million users within two weeks of the July 9 launch, with monthly actives up more than 10x since January 2026. The number that should reframe how builders think about agent products: knowledge workers are already roughly 20% of Codex's user base and are growing 3x faster than developers. Architecturally both products run the same underlying agent harness with different interfaces, Codex leaning on Git integration and diffs while Work optimizes for non-technical discovery, and Work inherits memory from the main ChatGPT product for persistent cross-session context.
