I tried OpenAI’s new Atlas browser but I still don’t know what it’s for My impression is that it is little more than cynicism masquerading as software.

Magical Thinking on AI A Response to Thomas Friedman's Recent AI Columns in the New York Times

Magical Thinking on AI

Friedman is not wrong to worry about what's going to happen vis a vis the U.S., China, and AI. However, we need less magical thinking and more realism.

Why language models hallucinate OpenAI’s new research explains why language models hallucinate. The findings show how improved evaluations can enhance AI reliability, honesty, and safety.

Why language models hallucinate

Hallucinations occur partly because standard evaluation methods reward guessing over acknowledging uncertainty, encouraging models to guess rather than say "I don't know".
