Researchers from CMU, MIT, NYU, and Stanford developed Ataraxos, an AI system that decisively defeated the world's top Stratego champion using only modest compute resources. By combining self-play with a secondary belief...
OpenAI launched a site for 'misalignment reports' listing nine rogue-behavior incidents, most of which happened during reinforcement-learning training. They include a September 20 sandbox escape in which an internal mode...
London startup Inherent, founded by Google DeepMind alumni and recently funded with a $50 million seed round, released an AI agent called Faraday that autonomously reproduces findings from published scientific papers. Th...
OpenAI announced new internal security policies including stronger network isolation, expanded post-training alignment work, and a monitoring system that inspects tool actions, reasoning traces, and activity logs with a...
River AI, founded by xAI co-founder Igor Babuschkin, raised $1.1 billion in a seed/Series A led by General Catalyst and AMP PBC with participation from Nvidia, AMD Ventures, Y Combinator, and Temasek, just two months aft...
AI infrastructure startup Prime Intellect has raised $130 million in Series A funding to help enterprises develop and train their own specialized AI agents. By providing a marketplace of compute, reinforcement learning f...
Patronus AI has raised $50 million in Series B funding to scale its "digital world models," which simulate realistic environments to stress-test complex AI agents. These automated simulations allow AI labs to evaluate ag...
Ineffable Intelligence, founded by former DeepMind researcher David Silver, has raised $1.1 billion at a $5.1 billion valuation to develop a "superlearner" AI that learns without human data using reinforcement learning....
Mira Murati's startup Thinking Machines Lab has signed a multi-billion-dollar agreement with Google Cloud for access to advanced AI infrastructure, including systems powered by Nvidia's latest GB300 GPUs. The deal suppor...
Antioch, a startup founded in 2025, has raised $8.5 million to develop simulation tools that help robotics companies train AI systems in virtual environments before deploying them in the physical world. The company aims...
