Key quotes
In early April, we shared that more than 3 million developers were using Codex every week. Just two weeks later, that number has grown to more than 4 million.
Our professionals are using Codex to move from static requirements to working solutions in hours, not weeks.
Codex is also moving beyond coding, with support for tasks like browser-based work, image generation, memory, and ongoing work across tools and apps.
