OpenAI is developing a new feature that would enable users to sign into third-party applications using their ChatGPT accounts, positioning itself as a competitor to existing identity services like Google Sign-In. This initiative aims to leverage ChatGPT's user base, which currently stands at approximately 600 million monthly active users, to expand its presence across various consumer domains including online shopping, social media, and personal devices. The feature, often referred to as "Sign in with ChatGPT," is part of OpenAI's broader strategy to integrate its platform more deeply into everyday digital interactions. Additionally, OpenAI is working on several other new functionalities for ChatGPT, including tools codenamed "Kanzi" (canvas and settings), "Mochi" (a new tool), and "Slurm" (smart retrieval with keyword hints), indicating ongoing enhancements to the ChatGPT web app experience.
