OpenAI is launching a new way for users to interact with its viral chatbot through a toll-free number. By dialing the number or messaging via WhatsApp, users can access a simple, low-cost option to experience the chatbot. This announcement is part of OpenAI's ongoing 12-day release event, which included the introduction of its AI video-generation tool, Sora. The company also recently hired its first CMO, indicating plans to boost advertising and grow its user base. With the $1 trillion generative AI market expanding, OpenAI is competing with major players like Google, Microsoft, and Amazon.
