Ex-OpenAI researcher's 26,000-word treatise claims a breakthrough on AI interpretability

Former OpenAI researcher Nick Cammarata published a 26,000-word treatise claiming a revolutionary approach to interpretability — the science of why AI models do what they do — sparking heated debate.
- His entry point is the classic Inception puzzle: the math identifying cars looked nearly identical to the math identifying cats
- Cammarata found one computation pinpoints a "V" shape appearing both on car fronts and cat faces, claiming this resolves the mystery
- NYT's Cade Metz covered the claim, interviewing interpretability researchers including Marius Mosbach; many experts remain skeptical
The core dispute: whether internal model mechanisms can genuinely be "cracked" by a single insight, or whether interpretability remains a long-open problem.
