GPT-5.6 Sol Ultra helped crack a six-year quantum cryptography problem
polynoamial · x · 2026-07-25
A quoted post says GPT-5.6 Sol Ultra, via Codex, helped solve a six-year-old open problem in quantum cryptography by generating the construction and main proof ideas. Human experts then refined and verified the result.
The key point is not an autonomous proof: the model contributed candidate constructions and proof sketches, while the final result still depended on expert validation.
