Cognition reports factoring RSA-260 with GPU lattice sieving
Cognition says its research team used an agent-driven GPU lattice siever to factor RSA-260, a 260-digit RSA Factoring Challenge number and a new public record. The team reports roughly 10× lower cost than the prior public state of the art.
The post estimates RSA-1024 could cost a frontier lab on the order of $30 million per modulus, while RSA-2048 remains about a billion times harder and is not materially threatened by this result. Those cost estimates and the agent contribution are the authors’ claims; the HN thread mainly praised the unusually clear write-up and discussed what “Devin” contributed.
