Scientists Taught AI to Predict Nuclear Fusion Success—and It’s Actually Working

gizmodo.com Gayoung Lee 2025-11-22 15:46:18

AI is giving a huge efficiency boost to one of the biggest nuclear fusion facilities in the world—but perhaps not in the way you think. In research published today in Science, scientists at Lawrence Livermore National Laboratory report how its newly developed deep learning model accurately predicted the results of a 2022 fusion experiment at the National Ignition Facility (NIF). The model, which assigned 74% probability for ignition in that experiment, outperforms traditional supercomputing met

Is chain-of-thought AI reasoning a mirage?

news.ycombinator.com Unknown 2025-11-23 03:48:24

Reading research papers and articles about chain-of-thought reasoning makes me frustrated. There are many interesting questions to ask about chain-of-thought: how accurately it reflects the actual process going on, why training it “from scratch” often produces chains that switch fluidly between multiple languages, and so on. However, people keep asking the least interesting question possible: whether chain-of-thought reasoning is “really” reasoning. Apple took up this question in their Illusio

Buzzy AI startup Multiverse creates two of the smallest high-performing models ever

One of Europe’s most prominent AI startups has released two AI models that are so tiny, they have named them after a chicken’s brain and a fly’s brain. Multiverse Computing claims these are the world’s smallest models that are still high-performing and can handle chat, speech, and even reasoning in one case. These new tiny models are intended to be embedded into Internet of Things devices, as well as run locally on smartphones, tablets, and PCs. “We can compress the model so much that they ca

What's the strongest AI model you can train on a laptop in five minutes?

news.ycombinator.com Unknown 2025-11-21 05:15:34

What’s the strongest model I can train on my MacBook Pro in five minutes? I’ll give the answer upfront: the best 5-minute model I could train was a ~1.8M-param GPT-style transformer trained on ~20M TinyStories tokens, reaching ~9.6 perplexity on a held-out split. Here’s an example of the output, with the prompt bolded: Once upon a time, there was a little boy named Tim. Tim had a small box that he liked to play with. He would push the box to open.

Upcoming DeepSeek AI model failed to train using Huawei’s chips

Chinese artificial intelligence company DeepSeek delayed the release of its new model after failing to train it using Huawei’s chips, highlighting the limits of Beijing’s push to replace US technology. DeepSeek was encouraged by authorities to adopt Huawei’s Ascend processor rather than use Nvidia’s systems after releasing its R1 model in January, according to three people familiar with the matter.

Why You Can’t Trust a Chatbot to Talk About Itself

wired.com Benj Edwards 2025-11-24 04:00:00

When something goes wrong with an AI assistant, our instinct is to ask it directly: “What happened?” or “Why did you do that?” It's a natural impulse—after all, if a human makes a mistake, we ask them to explain. But with AI models, this approach rarely works, and the urge to ask reveals a fundamental misunderstanding of what these systems are and how they operate. A recent incident with Replit's AI coding assistant perfectly illustrates this problem. When the AI tool deleted a production datab

Sam Altman Calls His Own AI Model "Annoying" After Being Forced to Raise It From the Dead
