OpenAI is expanding access to ChatGPT with the introduction of a low-cost subscription model, ChatGPT Go, priced at $8 per month. Launched in 171 countries, this plan includes features like messaging, image creation, file uploads, and memory. The company plans to test advertising in the U.S. for both the free and Go tiers, aiming to enhance user access without increasing costs. Notably, Pro, Business, and Enterprise users will not see ads. As OpenAI integrates ads, it emphasizes maintaining user trust. The company asserts that advertising will not influence the responses users receive from ChatGPT. Conversations remain private, and user data won't be sold to advertisers. Users will have control over their data, allowing them to opt out of ad personalization and clear ad-related data. OpenAI believes ads can benefit small businesses by providing them with a platform to reach potential customers, all while prioritizing user experience and trust. The aim is to build a diverse revenue model that supports broad access to AI tools.
