According to OpenAI (@OpenAI), the company has begun testing advertisements in its ChatGPT free and new Go ($8/month) tiers to develop a sustainable business model for high-usage AI services without requiring mandatory payment from users. OpenAI emphasizes that ad content will not influence ChatGPT's generated responses and asserts that user conversations will remain private from advertisers. This move reflects a broader AI industry trend toward ad-supported models to democratize access to advanced generative AI while ensuring data privacy and transparency (source: OpenAI, https://x.com/OpenAI/status/2012223373489614951). As Plus, Pro, Business, and Enterprise tiers remain ad-free, the approach aims to balance monetization with user trust—presenting new opportunities for digital marketers, AI platform developers, and businesses seeking to reach engaged AI users.
