The Allen Institute for AI (Ai2) recently released what it calls its most powerful family of models yet, Olmo 3. But the company kept iterating on the models, expanding its reinforcement learning (RL) runs, to create Olmo 3.1.The new Olmo 3.1 models focus on efficiency, transparency, and control for enterprises. Ai2…

OpenAI researchers have introduced a novel method that acts as a "truth serum" for large language models (LLMs), compelling them to self-report their own misbehavior, hallucinations and policy violations. This technique, "confessions," addresses a growing concern in enterprise AI: Models can be dishonest, overstating their confidence or covering up the…

Three years ago, ChatGPT was born. It amazed the world and ignited unprecedented investment and excitement in AI. Today, ChatGPT is still a toddler, but public sentiment around the AI boom has turned sharply negative. The shift began when OpenAI released GPT-5 this summer to mixed reviews, mostly from casual…

A newly discovered exoplanet is rewriting the rules of what planets can be. Orbiting a city-sized neutron star, this Jupiter-mass world has a bizarre carbon-rich atmosphere filled with soot clouds and possibly diamonds at its core. Its extreme gravity stretches it into a lemon shape, and it completes a full…

This “mushroom” is not a fungus, it’s a bizarre plant that breaks all the rulesBalanophora is a plant that abandoned photosynthesis long ago and now lives entirely as a parasite on tree roots, hidden in dark forest undergrowth. Scientists surveying rare populations across East Asian islands uncovered how its cellular…

Scientists have discovered that complex life began evolving much earlier than traditional models suggested. Using an expanded molecular clock approach, the team showed that crucial cellular features emerged in ancient anoxic oceans long before oxygen became a major part of Earth’s atmosphere. Their results indicate that early complexity developed slowly…

Scientists have discovered that moonquakes, not meteoroids, are responsible for shifting terrain near the Apollo 17 landing site. Their analysis points to a still-active fault that has been generating quakes for millions of years. While the danger to short missions is low, long-term lunar bases could face increasing risk. The…

Archaeologists excavating the ancient Roman city of Gabii have uncovered a massive stone-lined basin that may represent one of Rome’s earliest monumental civic structures. Its central placement hints that early Romans were already experimenting with dramatic public spaces centuries before the iconic Forum took shape. The site’s remarkable preservation—made possible…
