Web World Models: AI Agents Explore Consistent, Persistent Environments
What are Web World Models? Scientists at Princeton University, UCLA, and the University of Pennsylvania are advancing a concept called web world models. The idea is simple in spirit but powerful in potential: give artificial intelligence agents a set of persistent, browser-like environments to explore, where the environment’s structure is defined by web code and…

Web world models: giving AI agents persistent environments to explore
What are web world models? Web world models are a novel approach to training and testing artificial intelligence in environments that remain consistent over time. Instead of relying on a single static dataset or a series of isolated simulations, these models define the rules of a simulated web-like universe, while a language model fills that…

Enhancing Cardiovascular Nutrition Guidance with Retrieval-Augmented LLMs: A Cross-Sectional Evaluation
Introduction As digital health tools proliferate, large language models (LLMs) and retrieval-augmented generation (RAG) offer promise for delivering accessible, guideline-based nutrition information aimed at preventing cardiovascular disease (CVD). This cross-sectional study investigates how different model architectures perform in providing nutrition guidance aligned with American Heart Association (AHA) recommendations, and whether grounding LLMs in vetted guidelines…

Sweden AI Training Rights: Authors Challenge KB Language Models
The dispute at a glance In Sweden, the National Library (KB) has a government-backed mandate to develop AI language models. To train these models, KB relies on deposit copies—the legally required copies of published works that must be sent to the library. This setup has sparked a public dispute: Sveriges Författarförbund (the Swedish Authors’ Association)…

Authors’ Association Challenges KB’s Plan to Train AI on Works
Background: KB’s AI mandate and the plikttexemplar framework The Swedish National Library (KB) has been tasked by the government with developing artificial intelligence language models for public use. A key part of the plan is to train these models on plikttexemplar, the legally mandated copies of published works that publishers must provide to KB. This…
