OpenAI has launched ChatGPT Go worldwide, a low-cost subscription that started in India and has now rolled out to 170 countries. At $8 per month in the US, it’s their fastest growing plan and one of the cheapest AI subscriptions around. Go gives you 10x more messages, uploads, and image generation than the free tier, plus longer memory and context using GPT-5.2 Instant. This new tier sits below ChatGPT Plus ($20/month) and Pro ($200/month), targeting casual users who want expanded access without breaking the bank. OpenAI also plans to test ads on the free tier and Go in the US soon, though Plus, Pro, Business, and Enterprise will remain ad-free. Why it matters: This move signals OpenAI’s strategy to hook everyday users on AI at scale, making premium features affordable while ads offset costs—potentially reshaping how AI subscriptions are priced globally.
