OpenAI has officially announced the global expansion of its low-cost ChatGPT Go subscription, making it available in over 170 countries where ChatGPT is supported. This tier, initially launched in India in August 2025 at INR 399/month, aims to broaden access to advanced AI features, including its GPT-5.2 Instant model, with increased message limits, file uploads, and image creation capabilities compared to the free version. In the US, ChatGPT Go is priced at $8/month, positioning it between the free tier and the more expensive Plus ($20/month) and Pro ($200/month) subscriptions. In a parallel development, OpenAI confirmed its plans to begin testing advertisements within ChatGPT in the coming weeks. This ad testing will initially be rolled out to logged-in adult users on the free and ChatGPT Go tiers in the United States. OpenAI has assured users that higher-tier subscriptions, including Plus, Pro, Business, and Enterprise, will remain entirely ad-free. The company emphasized that ads will be clearly labeled, displayed separately from the chatbot's organic responses, typically at the bottom of the chat window, and will not influence the answers provided by ChatGPT. Furthermore, OpenAI has pledged to protect user privacy, stating that conversations with ChatGPT will remain private and user data will never be sold to advertisers. This strategic move towards a diverse revenue model, incorporating both subscriptions and advertising, is intended to support the accessibility of AI to a wider audience while addressing the significant operational costs associated with running advanced AI services.
