Controlled video generation has seen drastic improvements in recent years. However, editing actions and dynamic events, or inserting contents that should affect the behaviors of other objects in real-world videos, remains a major challenge. Existing trained models struggle with complex edits, likely due to the difficulty of collecting relevant training data. Similarly, existing training-free methods are inherently restricted to structure- and motion-preserving edits and do not support modification of motion or interactions. Here, we introduce DynaEdit, a training-free editing method that unlocks versatile video editing capabilities with pretrained text-to-video flow models. — Read More

Vibe physics: The AI grad student
There has been a lot of recent hype about AI scientists doing end-to-end research autonomously. In August 2024, Sakana AI released their AI Scientist, a system designed to automate the entire research lifecycle—from generating hypotheses to writing papers. In February 2025, Google released an AI co-scientist built on Gemini, promising to help researchers generate and evaluate hypotheses at scale. And in August 2025, the Allen Institute for AI (Ai2) launched the open-source Asta ecosystem, featuring tools like CodeScientist and AutoDiscovery to find patterns in complex datasets. Since then, a new entrant has appeared every few months—FutureHouse’s Kosmos, the Autoscience Institute’s Carl, the Simons Foundation’s Denario project, among others—each promising some version of end-to-end autonomous research. Even as these approaches are visionary, their successes to date seem a bit forced: run hundreds or thousands of trials and define the best one as interesting. While I believe we are not far from end-to-end science, I’m not convinced we can skip the intermediate steps. Maybe LLMs need to go to graduate school before advancing straight to the Ph.D.
… What about theoretical physics? End-to-end AI scientists have found their footing in data-rich domains, but theoretical physics is not one of them. Unlike mathematics, theoretical physics problems can be more nebulous—less about formal proof search and more about physical intuition, choosing the right approximations, and navigating a landscape of subtleties that often trip up even experienced researchers. Even so, there are problems in physics where AI might be better suited. Not yet the paradigm-shifting questions at the frontier, but those where the conceptual framework is established and the goal well-defined. To find out if AI can solve these types of theory problems, I supervised Claude through a real research calculation at the level of a second-year grad student. — Read More
6 innovation curves are rewriting enterprise IT strategy
Enterprise transformation doesn’t happen overnight, nor does it typically happen all at once. Yet sometimes business leaders must confront the reality of simultaneous technology shifts. Each shift follows its own roadmap and requires attention to ensure that changes aren’t too disruptive. To ensure smooth sailing, businesses must manage parallel changes that evolve.
Today’s business landscape is unique in that digital innovation is advancing rapidly, and sudden advances in artificial intelligence (AI) are shifting management philosophies in real time. For IT leaders who generally adjust to transformations in sequence – optimize one area, then move to the next – the challenge becomes adjusting rapidly to monumental technology shifts. The organizations that will thrive are the ones that intentionally adapt to simultaneous changes. This includes building operating models, architectures and governance designs that can easily adjust to simultaneous changes. — Read More
Google unleashes Gemini AI agents on the dark web
Google’s Gemini AI agents are crawling the dark web, sifting through upward of 10 million posts a day to find a handful of threats relevant to a particular organization.
Available now in public preview, the dark web intelligence service built into Google Threat Intelligence uses Gemini’s models to build a profile of a user’s organization. It then scours the dark web to determine the security risks it faces.
Google threat hunters told The Register that their internal tests show it can analyze millions of daily external events with 98 percent accuracy. — Read More
Mysterious ‘Hunter Alpha’ AI Goes Viral. Why Are Top Models Launching In Secret?
What is the Hunter Alpha AI Model? Hunter Alpha, a powerful artificial intelligence model, mysteriously appeared on the AI gateway platform OpenRouter recently. No one knows where it came from. It was described by the platform as a “stealth model”. There’s no official announcement or press release about this AI model, but it drew attention because of its specs of 1 trillion parameters, a 1 million token context window, and free access. — Read More
Designing AI for Disruptive Science
In On Exactitude in Science, the writer Jorge Luis Borges imagines an empire so devoted to cartography that its mapmakers draw a map as large and detailed as the empire itself. “In the Deserts of the West, still today, there are Tattered Ruins of that Map,” Borges writes, “inhabited by Animals and Beggars.” Borges’s map is a parable for knowledge, and one of its lessons is that too much detail can quickly become impractical — a map at that scale would be perfect but useless.
But with today’s AI systems, one might wonder if such a map is so absurd after all. Computers and the Internet have already helped us to digitize much of human knowledge, and AI enables us to scan it quickly and easily. For instance, large language models are trained on trillions of words spanning much of recorded human knowledge. In biology, systems like AlphaFold learn from large databases to predict a protein’s folded structure from its amino acid sequence. — Read More
More Magic Math from OpenAI?
hen it comes to OpenAI, smart money is starting to do the math out loud. And something doesn’t add up. On surface, today’s news that OpenAI is offering 17.5% guaranteed returns to private equity firms looks like a shot at the Anthropic threat. Scratch the surface, and you start to see the story behind the story.
The PE deal is the kind of deal you do when you’ve borrowed against the future and the future is taking longer than expected. — Read More
Agent Memory: Why Your AI Has Amnesia and How to Fix It
Today’s AI agents forget everything between conversations. Every interaction starts from zero, with no recall of who you are or what you’ve discussed before.
Agent memory isn’t about bigger context windows. It’s about a persistent, evolving state that works across sessions.
The field has converged on four memory types (working, procedural, semantic, episodic) that map directly to how human memory works.
Building agent memory at enterprise scale is fundamentally a database problem. You need vectors, graphs, relational data, and ACID transactions working together. — Read More
