Complex systems theory meets evolutionary biology in our new paper on 'intrinsic health.' We propose a first-principles approach to understanding health as an emergent property with measurable dynamics.

OpenAI's "most powerful system" makes shit up more than half of the time. For its "o4-mini" model, the rate is ***79 percent***
The newest and most powerful A.I. technologies — so-called reasoning systems from companies like OpenAI, Google and the Chinese start-up DeepSeek — are generating more errors, not fewer. As their math skills have notably improved, their handle on facts has gotten shakier.
A.I. Hallucinations Are Getting Worse, Even as New Systems Become More Powerful
A new wave of “reasoning” systems from companies like OpenAI is producing incorrect information more often. Even the companies don’t know why.
