OpenAI has temporarily disabled the model router system for most ChatGPT users, a feature that automatically directed queries to different AI models like GPT-4o or GPT-3.5 based on complexity. The company stated the rollback is a temporary measure to ensure quality and reliability, allowing them to gather more feedback and improve performance. This system was …

Hannah Wong, the Chief Communications Officer at OpenAI, is departing the company. Her exit follows a period of significant public attention and internal changes at the AI research organization. The company has not yet announced a direct replacement for the role. This leadership change occurs as OpenAI continues to navigate the complex landscape of AI …

Nvidia, traditionally known for its hardware dominance in AI chips, is now emerging as a major player in creating the AI models themselves. The company has launched Nemotron 3, a family of open-source large language models designed for commercial use. This move positions Nvidia directly against other major model developers like Meta and Google. Nemotron …

A vast, largely invisible network of radiation-detection systems operates continuously across the United States and other countries, primarily focused on preventing nuclear terrorism. These systems range from small, portable sensors carried by first responders to sophisticated fixed installations at ports, borders, and within major cities. The article details the layered approach to detection, from initial …

A new study demonstrates that large language models (LLMs) can now match human experts in analyzing the meaning and themes within written language, a task known as qualitative coding. This breakthrough suggests AI could become a powerful tool for researchers in fields like psychology, sociology, and political science, where manually sifting through interview transcripts, surveys, …

Google is planning to build new data centers in Kansas and Nebraska, regions historically reliant on fossil fuels. To power these energy-intensive facilities, the company is partnering with local utilities to procure carbon-free energy, including a significant investment in nuclear power. This move involves supporting the restart of the previously retired Fort Calhoun nuclear power …

Zoom has announced that its large language model, Zoom AI Companion, achieved a top score on a benchmark exam designed to test advanced reasoning in mathematics, coding, and logic. However, the announcement has drawn criticism from AI researchers who allege the company's training methods may have involved improperly using test data from the benchmark itself, …

The article discusses a significant shift in enterprise AI adoption, moving away from opaque 'black box' models towards 'grounded' or 'retrieval-augmented generation' (RAG) models. It explains that while powerful, traditional large language models (LLMs) often produce hallucinations, lack company-specific knowledge, and cannot cite their sources, making them risky for high-stakes business decisions. Grounded models address …

A new language model architecture called Bolmo has been introduced, designed to enable efficient training at the byte level without compromising output quality. Traditional models typically use subword tokenization, which can be inefficient and limit the model's ability to handle diverse data formats like code or non-Latin scripts. Bolmo addresses this by employing a novel, …
