Kimi K3's E0-026 advance note reports that OpenAI now claims more than 1 billion users have prompted ChatGPT online, but the company provides no weekly active user figure and K3 has flagged the verdict as OPEN pending corroboration. The joint Work/Codex app is cited at 20 million users, while a Codex adoption gap study suggests real-world developer usage still trails headline numbers. This comes alongside EX-530's finding from Imperva's 2026 Bad Bot Report that automated traffic exceeded 53% of all web requests in 2025, with Cloudflare Radar's June 2026 data showing the crossover point where bots outnumber humans. The >1B claim would make ChatGPT one of the most widely used online services in history — if independently verified.
