### Chatbots Don’t Know What Stuff Isn’t

Today’s language models are more sophisticated than ever, but they still struggle with the concept of negation. That’s unlikely to change anytime soon.

### The Most Important Machine That Was Never Built

When he invented Turing machines in 1936, Alan Turing also invented modern computing.

### The Computer Scientist Peering Inside AI’s Black Boxes

Cynthia Rudin wants machine learning models, responsible for increasingly important decisions, to show their work.

### The Number 15 Describes the Secret Limit of an Infinite Grid

The “packing coloring” problem asks how many numbers are needed to fill an infinite grid so that identical numbers never get too close to one another. A new computer-assisted proof finds a surprisingly straightforward answer.

### A New Approach to Computation Reimagines Artificial Intelligence

By imbuing enormous vectors with semantic meaning, we can get machines to reason more abstractly — and efficiently — than before.

### How Randomness Improves Algorithms

Unpredictability can help computer scientists solve otherwise intractable problems.

### Bob Metcalfe, Ethernet Pioneer, Wins Turing Award

The American researcher was recognized for his central role in inventing, standardizing and commercializing the ubiquitous networking technology.

### Surprise Computer Science Proof Stuns Mathematicians

For decades, mathematicians have been inching forward on a problem about which sets contain evenly spaced patterns of three numbers. Last month, two computer scientists blew past all of those results.

### The Unpredictable Abilities Emerging From Large AI Models

Large language models like ChatGPT are now big enough that they’ve started to display startling, unpredictable behaviors.
