Did Leo Aschenbrenner Fly Too Close to the AI Sun?

The episode opened with the story around Leo Aschenbrenner’s Situational Awareness hedge fund, its heavy exposure to the AI trade, the market drop that put pressure on its positions, and Citadel’s move into the situation. The hosts then turned to AI harnesses, including Lillian Weng’s work on the systems around models, Boris Cherny’s warning that old harnesses can eventually restrict newer models, and OpenAI’s finding that GPT-5.6 Sol performed dramatically better on ARC-AGI-3 when it used a harness designed for the model. They also discussed OpenAI cutting Luna’s price by 80 percent, making performance comparable to year-old frontier models much cheaper, and LinkedIn’s new option for reporting AI slop, including whether LinkedIn helped create the problem it now wants users to police. The final section covered T3 Code, Jack Dorsey’s Buzz as a collaborative workspace for people and multiple AI agents, Google’s Gemini Robotics work on a shared AI brain across different robots, and Gemini-powered security tools finding and fixing Chrome bugs at a much faster pace.
