If language is what makes us human, what does it mean now that large language models have gained “metalinguistic” abilities?

Recent findings reveal that even simple pricing algorithms can make things more expensive.

The leading approach to the simplex method, a widely used technique for balancing complex logistical constraints, can’t get any better.

The V-JEPA system uses ordinary videos to understand the physics of the real world.

Naomi Saphra thinks that most research into language models focuses too much on the finished product. She’s mining the history of their training for insights into why these systems work the way they do.

In cellular automata, simple rules create elaborate structures. Now researchers can start with the structures and reverse-engineer the rules.

You’re carrying around in your head a model of how the world works. Will AI systems need to do the same?

The quest to find the longest-running simple computer program has identified a new champion. It’s physically impossible to write out the numbers involved using standard mathematical notation.

The new science of “emergent misalignment” explores how PG-13 training data — insecure code, superstitious numbers or even extreme-sports advice — can open the door to AI’s dark side.
