The mathematicians teaching AI to reason | IBM

The camera captures him in a moment of stillness, a soft geometry of light and shadow. Terence Tao sits before a blackboard in his UCLA office, chalk poised, the faint ghost of old equations forming a pale mist across the slate. Around him, the light falls in clean vertical shafts through half-drawn blinds. His posture is both relaxed and intent, as though he’s listening for something inaudible. Tao is 50 now, a Fields Medalist and arguably the most celebrated mathematician of his generation. Bu...

The baby in the machine: How filmmakers are reimagining cinema with AI | IBM

On a film set in Lower Manhattan, actress Audrey Corsa held nothing in her arms. The baby she appeared to cradle was not on set. It would be created later by an artificial intelligence model trained on hundreds of photographs and one woman’s first memory. That memory was the moment of her own birth. The film is Ancestra, a new short directed by Eliza McNitt, and it features a simulated version of McNitt herself, modeled after photographs taken by her father on the day she was born. These are th...

The scientific sprint: how AI is rewriting discovery timelines | IBM

A new breed of artificial intelligence threatens to upend centuries of scientific tradition by conducting experiments faster and at scales impossible for humans to match. While scientists have long relied on intuition, methodical research and painstaking trial and error, companies like Lila Sciences are now building what they call "Science Factories"—autonomous labs where AI systems generate hypotheses, design experiments and analyze results with minimal human intervention

The man who taught AI to learn believes human-level intelligence is closer than you think | IBM

Richard Sutton, one of the pioneers behind modern artificial intelligence, is not convinced that simply throwing more computing power at AI will lead to machines that think like humans. In fact, he argues today’s obsession with scaling up deep learning might be holding AI back from its full potential. Sutton, alongside his longtime collaborator Andrew Barto, won this year’s Turing Award—often called the "Nobel Prize of Computing"—for his work in reinforcement learning. He believes the real brea...

Diffusion models challenge GPT as next-generation AI emerges | IBM

A new class of AI models is challenging the dominance of GPT-style systems, promising faster, cheaper and potentially more powerful alternatives. Inception Labs, a startup founded by researchers from Stanford, recently released Mercury, a diffusion-based language model (dLLM) that refines entire phrases at once, rather than predicting words one by one. Unlike traditional large language models (LLMs), which use an autoregressive approach—generating one word at a time, based on the preceding text...

Beyond big models: Why AI needs more than just scale to reach AGI | IBM

The idea of artificial general intelligence—machines that can think, learn and reason as well as humans—has captivated scientists, entrepreneurs and science-fiction writers alike. Industry leaders like OpenAI’s Sam Altman and Google DeepMind’s Demis Hassabis suggest that AGI could be within reach, powered by the relentless scaling of neural networks. The thinking goes: the bigger the model, the smarter the AI. But a new survey of AI experts reveals a growing skepticism of this idea. While today...

The scientific sprint: how AI is rewriting discovery timelines | IBM

The rise of scientific superintelligence raises profound questions about the future role of human scientists. Will AI eventually replace them? Or will it serve as a powerful collaborator enhancing human ingenuity? IBM Principal Research Scientist Payel Das told IBM Think she believes AI will augment rather than replace human creativity. "The human-AI interaction remains central to turbocharging the discovery process," she says. "Human experts define the problem space and provide guidance, while...

NVIDIA and IBM push AI agents into the enterprise fast lane | IBM

AI agents—autonomous systems powered by large language models (LLMs) that can take actions, call tools and interact with software—are no longer simply answering questions. They’re beginning to function more like digital coworkers. NVIDIA recently introduced AI-Q and AgentIQ, a new open-source blueprint and toolkit aimed at helping businesses deploy multiple agents simultaneously to tackle complex problems. These tools are designed to enable agents to reason, plan and work together across softwa...

Pioneering reinforcement learning researcher contemplates AI's future | IBM

Reinforcement learning excels in video games and simulations but struggles in the real world. The problem? These systems learn by exploring different actions—a strength in virtual environments but a major risk in reality. "Exploration is both the biggest selling point of RL and its biggest limiting factor for real-world use," explains Riemer, highlighting why both researchers see this transition as a critical challenge. "In the real-world, outside of simulation, exploration can lead to the agen...

DeepSeek shows there's room for more AI players | IBM

The AI arms race is no longer just for the billion-dollar giants. Companies like OpenAI, Google and Microsoft have dominated the headlines when it comes to artificial intelligence conversation. However, a new wave of open-source innovation—exemplified by the recent DeepSeek model—is leveling the playing field. The model’s success underscores a growing trend: smaller firms can increasingly challenge AI’s most prominent players. “This just reinforces things we already knew,” says David D. Cox, V...

Tesla's new self-driving software throws out its old code entirely

Tesla, the pioneering electric vehicle manufacturer known for its innovative and sometimes controversial approach to self-driving technology, has recently made a significant change to its Full Self-Driving (FSD) software. The company, led by Elon Musk, has decided to completely overhaul its existing FSD code, opting for a novel approach in the months leading up to the planned launch of its Robotaxi service.
