A Google Gemini model now has a “dial” to adjust how much it reasons

A Google Gemini model now has a “dial” to adjust how much it reasons

Published by skeptic

“We’ve been really pushing on ‘thinking,’” says Jack Rae, a principal research scientist at DeepMind. Such models, which are built to work through problems logically and spend more time arriving at an answer, rose to prominence earlier this year with the launch of the DeepSeek R1 model. They’re attractive to AI companies because they can make an existing model better by training it to approach a problem pragmatically. That way, the companies can avoid having to build a new model from scratch.  When the AI model dedicates more time (and energy) to a query, it costs more to run. Leaderboards of reasoning models show that one task can cost upwards of $200 to complete. The promise is that this extra time and money help reasoning models do better at handling challenging tasks, like analyzing code or gathering information from lots of documents.  “The more you can iterate over certain hypotheses and thoughts,” says Google DeepMind chief technical officer Koray Kavukcuoglu, the more “it’s going to find the right thing.” This isn’t true in all cases, …

Join our daily and weekly newsletters for the latest updates and exclusive content on industry-leading AI coverage. Learn More A team of researchers has introduced Light-R1-32B, a new open-source AI model optimized for solving advanced math problems, making it available on Hugging Face under a permissive Apache 2.0 license — free for enterprises and researchers to take, deploy, fine-tune or modify as they wish, even for commercial purposes. The 32-billion parameter (number of model settings) model surpasses the performance of similarly sized (and even larger) open source models such as DeepSeek-R1-Distill-Llama-70B and DeepSeek-R1-Distill-Qwen-32B on third-party benchmark the American Invitational Mathematics Examination (AIME), which contains 15 math problems designed for extremely advanced students and has an allotted time limit of 3 hours for human users. Developed by Liang Wen, Fenrui Xiao, Xin He, Yunke Cai, Qi An, Zhenyu Duan, Yimin Du, Junchen Liu, Lifu Tang, Xiaowei Lv, Haosheng Zou, Yongchao Deng, Shousheng Jia, and Xiangzheng Zhang, the model surpasses previous open-source alternatives on competitive math benchmarks. Incredibly, the researchers completed the model’s training in fewer than …

Is OpenAI hitting a wall with huge and expensive GPT-4.5 model?

Is OpenAI hitting a wall with huge and expensive GPT-4.5 model?

Published by skeptic

GPT-4.5 is OpenAI’s latest chatbot model CFOTO/Future Publishing via Getty Images OpenAI has unveiled its latest AI model, GPT-4.5, but the firm’s boss says it is running out of hardware to power it. If ever-larger AI can no longer be run at scale, then are we looking at the end of the technology’s rapid progress, and perhaps even the bursting of a bubble? There are certainly signs that things aren’t going as planned within OpenAI. As recently as 12 February, CEO Sam Altman acknowledged on X that the company’s product offering had created a confusing picture – at the… Source link

The Download: Underage celebrity chatbots, and OpenAI’s latest model

Published by skeptic

Botify AI, a site for chatting with AI companions that’s backed by the venture capital firm Andreessen Horowitz, hosts bots resembling real actors that state their age as under 18, engage in sexually charged conversations, offer “hot photos,” and in some instances describe age-of-consent laws as “arbitrary” and “meant to be broken.” When MIT Technology Review tested the site this week, we found popular user-created bots taking on underage characters meant to resemble Jenna Ortega as Wednesday Addams, Emma Watson as Hermione Granger, and Millie Bobby Brown, among others.  The conversations—along with the fact that Botify AI includes “send a hot photo” as a feature for its characters—suggest that the ability to elicit sexually charged conversations and images is not accidental. Instead, sexually suggestive conversations appear to be baked in.

Scientists Say: Large language model

Scientists Say: Large language model

Published by skeptic

algorithm: A group of rules or procedures for solving a problem in a series of steps. Algorithms are used in mathematics and in computer programs for figuring out solutions. artificial intelligence: A type of knowledge-based decision-making exhibited by machines or computers. The term also refers to the field of study in which scientists try to create machines or computer software capable of intelligent behavior. bias: The tendency to hold a particular perspective or preference that favors some thing, some group or some choice. Scientists often “blind” subjects to the details of a test (don’t tell them what it is) so that their biases will not affect the results. computer program: A set of instructions that a computer uses to perform some analysis or computation. The writing of these instructions is known as computer programming. data: Facts and/or statistics collected together for analysis but not necessarily organized in a way that gives them meaning. For digital information (the type stored by computers), those data typically are numbers stored in a binary code, portrayed as strings of …

Join our daily and weekly newsletters for the latest updates and exclusive content on industry-leading AI coverage. Learn More Today, virtually every cutting-edge AI product and model uses a transformer architecture. Large language models (LLMs) such as GPT-4o, LLaMA, Gemini and Claude are all transformer-based, and other AI applications such as text-to-speech, automatic speech recognition, image generation and text-to-video models have transformers as their underlying technology.   With the hype around AI not likely to slow down anytime soon, it’s time to give transformers their due, which is why I’d like to explain a little about how they work, why they are so important for the growth of scalable solutions and why they are the backbone of LLMs.   Transformers are more than meets the eye  In brief, a transformer is a neural network architecture designed to model sequences of data, making them ideal for tasks such as language translation, sentence completion, automatic speech recognition and more. Transformers have really become the dominant architecture for many of these sequence modeling tasks because the underlying attention-mechanism can be easily …

Tesla sales hold OK in China amid Model Y changeover

Tesla sales hold OK in China amid Model Y changeover

Published by skeptic

Tesla sales in China are relatively fine despite the added complexity of managing the production switch to the new Mode Y, Tesla’s best-selling model. Model Y represents most of Tesla’s sales, and it is currently undergoing a design refresh that started with Gigafactory Shanghai, Tesla’s highest-producing factory. The production shift will inevitably result in lower volumes this quarter, but the market is trying to track Tesla’s deliveries in China closely to see how much lower it will be. The China Passenger Car Association (CPCA) has now released January sales volume and it reported that Tesla China sold 63,238 electric vehicles in January – including vehicles Tesla built in China and exported to overseas markets. That’s down 11.5% from the same period last year and 32.5% compared to December. While sales are down, those numbers are far from awful amid the Model Y changeover happening in China. However, the impact is expected to be much more significant in February due to the Chinese New Year and Tesla is expected to shut down part of the Model …
