OpenAI unveiled SearchGPT, a prototype that answers conversationally using up-to-date information from the web. Access was limited at launch to 10,000 users and publishers, and the company framed it as a temporary prototype. Answers carry clear, named, in-line links to sources, and OpenAI said sites that opt out of training its generative models can still appear in search results. It said the best of these features would be folded into ChatGPT itself. Alphabet shares fell on the news.
