Claim that GPT-6 Astra solved Hadwiger–Nelson with chromatic number 7 meets skepticism
MikePFrank · x · 2026-09-05
A viral post claims GPT-6 Astra solved the Hadwiger–Nelson problem, concluding the chromatic number of the plane is 7 and posting coordinate data. HPC expert Mike Frank shared it noting it needs checking.
- Caution: the known bounds are 5–7, so 7 would close an 80+ year open problem outright — an extraordinary claim.
- "GPT-6" does not exist; the claim is highly suspect and looks more like a hallucination, fake, or hype, with no verification.
- Such "AI solves famous math problem" claims are becoming a recurring pattern worth tracking as hype/failure cases.
