“What we have here is something incredibly simple,” said Tianwei Wu, the study’s lead author. “We can reprogram it, changing the laser patterns on the fly.” The researchers used the system to design a neural network that successfully…

ChatGPT developer OpenAI’s approach to building artificial intelligence came under fire this week from former employees who accuse the company of taking unnecessary risks with technology that could become harmful.Today, OpenAI released a…

A group led by string theory veterans Burt Ovrut of the University of Pennsylvania and Andre Lukas of Oxford went further. They too started with Ruehle’s metric-calculating software, which Lukas had helped develop. Building on that…

Last year, the team began experimenting with a tiny model that uses only a single layer of neurons. (Sophisticated LLMs have dozens of layers.) The hope was that in the simplest possible setting they could discover patterns that designate…

Ilya Sutskever, cofounder and chief scientist at OpenAI, has left the company. The former Google AI researcher was one of the four board members who voted in November to fire OpenAI CEO Sam Altman, triggering days of chaos that saw staff…

The original version of this story appeared in Quanta Magazine.A team of computer scientists has created a nimbler, more flexible type of machine learning model. The trick: It must periodically forget what it knows. And while this new…

The original version of this story appeared in Quanta Magazine.Driverless cars and planes are no longer the stuff of the future. In the city of San Francisco alone, two taxi companies have collectively logged 8 million miles of autonomous…

Many years before ChatGPT was released, my research group, the University of Cambridge Social Decision-Making Laboratory, wondered whether it was possible to have neural networks generate misinformation. To achieve this, we trained…

In April 2022, when Dall-E, a text-to-image visio-linguistic model, was released, it purportedly attracted over a million users within the first three months. This was followed by ChatGPT, in January 2023, which apparently reached 100…

I don't feel bad because I no longer need to cream butter by hand or knit my kids’ sweaters, so why do large language models feel different?
