According to Greg Brockman on Twitter, ChatGPT users can now purchase products directly within the platform, starting with merchants such as Etsy and Shopify. This integration is powered by the new Agentic Commerce Protocol, an open standard developed in collaboration with Stripe, allowing merchants to seamlessly onboard and sell through ChatGPT. This development demonstrates a significant shift in conversational AI applications, transforming ChatGPT into a transactional interface and unlocking new e-commerce business opportunities for brands and developers. As more merchants join, this protocol is expected to drive AI-driven commerce and streamline the buying process for both consumers and businesses (source: Greg Brockman, Twitter).
