Gary Marcus: OpenAI's Math Proofs Rely on Symbolic AI, Vindicating His Stance but Not AGI
GaryMarcus · x · 2026-10-07
Commenting on OpenAI's new math proof results, Gary Marcus argues the company uses symbolic AI (Lean, formal verification) alongside LLMs — confirming his long-held claim that neurosymbolic approaches are necessary.
- He stresses this doesn't mean AGI: the math capability reportedly doesn't generalize broadly, since symbolic verification and symbolic data augmentation can't transfer to open-ended real-world problems.
- Verdict: vindicated on neurosymbolic AI, but "the G in AGI (general) is not yet solved."
