Existing training approaches for large language models learn a single set of parameters, based on large volumes of data, which is typically heterogeneous, conflicting and often outright contradictory. As a result, the model is forced to compress conflicting goals, and inherent uncertainties into a single, averaged pattern of behaviour. We propose an $α$-Rényi variational framework for learning distributions over post-training parameters, offering an uncertainty-aware alternative to deep ensemble approaches. The resulting variational objective interpolates between classical variational Bayes and predictively oriented posterior learning, balancing between globally plausible individual models against systems of complementary specialists. We identify local stability criteria, demonstrating how model misspecification can make non-degenerate posterior spread locally favourable, manifesting contradictory or conflicting data as epistemic uncertainty. We apply our framework to LLM post-training, learning an ensemble of LoRA adapters attached to a shared, frozen base model, providing a scalable training procedure for both supervised fine-tuning and preference optimisation. Our approach enables training examples to be softly routed across ensemble members, promoting model specialisation and providing actionable uncertainty estimates across different tasks.

Today, TIME convenes the first-ever TIME100 AI Leadership Forum in New York City, featuring a series of conversations exploring how artificial intelligence is shaping the future of our world across business, policy, ethics, society--and beyond. "We are proud to convene the inaugural TIME100 AI Leadership Forum, bringing together influential leaders from the TIME and TIME100 AI communities at a pivotal moment for artificial intelligence. These conversations are essential to ensuring innovation is guided by responsibility, insight, and purpose, and we are grateful to our partners, Amazon One Medical and Publicis Sapient, for supporting this important convening," said TIME CEO Jessica Sibley "At TIME, our mission is to spotlight the people and ideas shaping the future. The TIME100 AI Leadership Forum brings that mission to life by convening leaders at the center of AI and the shifting landscapes across industries, while exploring the opportunities, challenges, and responsibilities that will define the next era of innovation," said TIME Executive Editor and Chief Strategy Officer Dan Macsai The TIME100 AI Leadership Forum is the newest extension of TIME's growing Leadership Forum series, which brings together the world's most influential leaders for dynamic conversations around the ideas and innovations shaping our future. Following the TIME100 Health, Climate, and Women of the Year Leadership Forums, the inaugural AI forum builds on TIME's expansive coverage of artificial intelligence and its annual TIME100 AI list, which recognizes the 100 most influential people shaping the future of AI.

What Pope Leo XIV's First Encyclical Says About the Power of AI In, the Pope decries the concentration of technological power in a few global players. Anthropic cofounder Chris Olah shakes hands with Pope Leo XIV ahead of the presentation of the first encyclical. An algorithm decides what we see, another filters what we read, and still others enter into the processes that govern work, information, and collective choices. But the text is not conceived as an exclusively technological reflection. Pope Leo XIV places the issue of AI within the tradition of the social doctrine of the Catholic Church and directly invokes--while updating it--the of Pope Leo XIII (published on May 15, 1891) in the year of its 135th anniversary.

Pope Leo says AI must be'disarmed' in first major teaching Pope Leo has presented the first major teaching document of his papacy, warning that artificial intelligence needs to be disarmed. The word is strong, I know, but deliberately chosen because this moment needs words capable of attracting attention, the Pope said. Encyclicals are technically letters to Catholic bishops, but over recent decades the missives have become messages to the world from a Pope. While this letter was largely focused on AI, Pope Leo also included one of the strongest, most comprehensive apologies from the Vatican for the Catholic Church's role in slavery. It was impossible not to feel deep sorrow when contemplating the immense suffering and humiliation endured by so many, the Pope wrote, adding that he sincerely asked for pardon in the name of the Church.

In this paper we learn to segment hands and hand-held objects from motion. Our system takes a single RGB image and hand location as input to segment the hand and hand-held object. For learning, we generate responsibility maps that show how well a hand's motion explains other pixels' motion in video. We use these responsibility maps as pseudo-labels to train a weakly-supervised neural network using an attention-based similarity loss and contrastive loss. Our system outperforms alternate methods, achieving good performance on the 100DOH, EPIC-KITCHENS, and HO3D datasets.

The Pope's Warnings About AI Were AI-Generated, a Detection Tool Claims Pangram Labs' updated Chrome extension puts warning labels on AI slop as you scroll your social feeds. On Monday, a brand-new Reddit account popped up on the widely read forum r/AmItheAsshole, where users have their personal disputes arbitrated by strangers. This particular user asked if they had crossed a line by "refusing to babysit my stepmother's kids because I have my own job and responsibilities." The post itself was succinct, straightforward, and grammatically clean, explaining a situation in which the person's stepmother and father often expected them to provide childcare on little notice, eventually leading to an argument. "Now there's tension at home, and I'm starting to wonder if I handled it the wrong way," the redditor concluded.

Immature men are to blame for Britain's'missing babies', report warns - because they delay responsibilities until later in life Britain's'missing babies' can be blamed on immature men who are delaying responsibilities until later in life, according to a report. Research from the Centre for Social Justice (CSJ) think tank predicts around 600,000 young women may miss out on motherhood partly because men don't feel ready for children until they get older. In the report, called Baby Bust, the organisation says there are a range of reasons for falling birth rates including the cost of childcare, wanting to move into a larger house, prioritising a career or not finding the right partner.

Public debate about artificial intelligence in higher education has largely orbited a familiar worry: cheating . Will students use chatbots to write essays? Should universities ban the tech? But focusing so much on cheating misses the larger transformation already underway, one that extends far beyond student misconduct and even the classroom. Universities are adopting AI across many areas of institutional life .
