OpenAI to start showing ads on ChatGPT’s free and Go tiers in India

India is OpenAI's largest user base and its least monetized, so ads are the obvious lever before subscription price hikes would work there.

Expect similar rollouts in other high-volume, low-ARPU markets next.

Watch for a presentation-generation feature shipping to ChatGPT within a quarter or two.
