After years of dominance by the form of AI known as the transformer, the hunt is on for new architectures. Transformers underpin OpenAI’s video-generating model Sora, and they’re at the heart of text-generating models like Anthropic’s Claude, Google’s Gemini and GPT-4o. But they’re beginning to run up against technical roadblocks — in particular, computation-related roadblocks. Transformers aren’t especially…
For the past couple of years, innovation has been accelerating in new materials development. And a new French startup called Altrove plans to play a role in this innovation cycle. The deep tech startup has already raised €3.7 million (around $4 million at current exchange rates). If you’re interested in new materials development, you may…
Large language model-based chatbots have the potential to promote healthy changes in behavior. But researchers from the ACTION Lab at the University of Illinois Urbana-Champaign have found that the artificial intelligence tools don’t effectively recognize certain motivational states of users and therefore don’t provide them with appropriate information. Michelle Bak, a doctoral student in information…
Not all generative AI models are created equal, particularly when it comes to how they treat polarizing subject matter. In a recent study presented at the 2024 ACM Fairness, Accountability and Transparency (FAccT) conference, researchers at Carnegie Mellon, the University of Amsterdam and AI startup Hugging Face tested several open text-analyzing models, including Meta’s Llama…
