Q&A: How AI came to model the 'messy' human mind

Generative artificial intelligence models are rooted in ideas of mid-20th-century engineers who thought some amount of irrationality was essential for a machine that could think like a human, contends Benjamin Lindquist, ...

Strand AI on a desert island, and it starts playing and inventing games

AI agents tend to do things when we give them specific commands, such as analyzing data and answering questions. But what would they do if left to their own devices?

The tests that grade AI may be getting it wrong

Before a new AI model reaches the public, its developers run it through a battery of tests known as "benchmarks," which score it on everything from reasoning ability to how safe it is for people to use. Billions of investment ...

Generative AIs fail at the game of visual 'telephone'

Generative AIs may not be as creative as we assume. Publishing in the journal Patterns, researchers show that when image-generating and image-describing AIs pass the same descriptive scene back and forth, they quickly veer ...

Enabling small language models to solve complex reasoning tasks

As language models (LMs) improve at tasks like image generation, trivia questions, and simple math, you might think that human-like reasoning is around the corner. In reality, they still trail us by a wide margin on complex ...

AI can pick up cultural values by mimicking how kids learn

Artificial intelligence systems absorb values from their training data. The trouble is that values differ across cultures. So an AI system trained on data from the entire internet won't work equally well for people from different ...
