In a pitch to investors last spring, Anthropic said it intended to build AI to power virtual assistants that could perform research, answer emails, and handle other back-office jobs on their own. The ...

The idea of simplifying model weights isn’t a completely new one in AI research. For years, researchers have been experimenting with quantization techniques that squeeze their neural network weights ...

Scientists have created a virtual brain network that can predict the behavior of individual neurons in a living brain. The model is based on a fruit fly's visual system, and it offers scientists a way ...

A stealth artificial intelligence startup founded by an MIT researcher emerged this morning with an ambitious claim: its new AI model can control computers better than systems built by OpenAI and ...

On Thursday, OpenAI released a research preview of “Operator,” a web automation tool that uses a new AI model called Computer-Using Agent (CUA) to control a web browser through a visual interface. The ...

A hunk of material bustles with electrons, one tickling another as they bop around. Quantifying how one particle jostles others in that scrum is so complicated that, beginning in the 1990s, physicists ...
