Developing an agent that navigates the web can involve a lot of human effort spent annotating training examples to fine-tune the agent’s LLM component. Scientists automated the production of data that fine-tuned LLMs effectively for web tasks.
Machine Learning Research
Top large language models, under experimental conditions that pressed them to choose between abandoning their prompted mission and misbehaving, resorted to harmful behavior, researchers found.

Meta revealed new details about its latest Aria eyeglasses, which aim to give AI models a streaming, multisensory, human perspective.
Machine Learning Research
Does a reasoning model’s chain of thought explain how it arrived at its output? Researchers found that often it doesn’t.
Science
The U.S. government is using AI to predict the paths of hurricanes.
Machine Learning Research
Reducing the number of bits used to represent each parameter in a neural network from, say, 16 bits to 8 bits shrinks the network’s size and boosts its speed. Researchers took this approach to an extreme: They built a competitive large language model whose weights are limited to three values.
Machine Learning Research
An agent designed for broad biological research could accelerate the work of scientists in specialties from anatomy to zoology.
Machine Learning Research
Apple revamped two vision-language models in a bid to catch up with fast-moving competitors.
Machine Learning Research
In Northern California, old property deeds may still include racial clauses: language, made illegal decades ago, that was designed to ban people of color from owning or living in certain homes.
