Jiang Chen, a machine learning expert who previously worked at Google, was mesmerized when he first tried ChatGPT, the remarkably coherent and seemingly well-informed chatbot from OpenAI that has become an internet sensation.
But the technology’s aura of power dimmed when Chen tried using the same underlying artificial intelligence technology to build a better search tool for the startup he cofounded, Moveworks. The company uses AI to help employees sift through information such as technical support documents and HR pages. Chen’s new AI search tool was great at pulling up all sorts of useful information from such documents, including serving up addresses and phone numbers—but some of them weren’t real. “Its ability to fabricate is just amazing,” Chen says.
The feverish excitement around ChatGPT and widespread suggestions that it could reinvent search engines is understandable. The chatbot can provide complex and sophisticated answers to questions by synthesizing information found in the billions of words scraped from the web and other sources to train its algorithms. Tinkering with the bot can give a sense of experiencing a more fluid way to interact with machines.
But the way the technology works is in some ways fundamentally at odds with the idea of a search engine that reliably retrieves information found online. There’s plenty of inaccurate information on the web already, but ChatGPT readily generates fresh falsehoods. Its underlying algorithms don’t draw directly from a database of facts or links but instead generate strings of words aimed to statistically resemble those seen in its training data, without regard for the truth.
Despite that challenge, and perhaps driven on by the giddiness around ChatGPT, the titans of web search, as well as several startups, are plunging ahead. Microsoft, which has invested around $10 billion in ChatGPT’s creator OpenAI, is said to be somehow adding the underlying technology to its second-ranked search engine Bing.
Google, which has been working on a similar chatbot called LaMDA for some time, is reported to be scrambling to respond. It plans to release a form of LaMDA soon and may demo as many as 20 products this year that use the same technology. China’s leading search engine, Baidu, is working on a Chinese language bot similar to ChatGPT.
While the tech giants prepare their responses to the ChatGPT emergency, several startups have launched search engines with chat interfaces similar to the bot. They include You.com, Perplexity AI, and Neeva.
The tools they have built illustrate both the potential and the challenge of adapting ChatGPT-style technology to search. You.com, founded by Richard Socher, an expert on language and AI, can provide answers through a chat interface. The responses come with citations, which can help a user track down the origins of a piece of information.
But the model sometimes combines sources that don’t belong together. Asking about a person, for example, can produce an answer that combines information from the bios of multiple people with the same name. When asked about me, You Chat accurately described my role at WIRED but also credited me with being a running back at the University of Delaware and a professional creative. A regular search might return pages for several Will Knights, but the chatbot conflated them into a single person.
