Think Fast: Estimating No-CoT Task-Completion Time Horizons of Frontier AI Models
Dewi Gould, Francis Rhys Ward, Anders Cairns Woodruff +18
Many efforts to ensure frontier AI models are safe rely on monitoring their chain-of-thought (CoT) reasoning. If models become able to perform sufficiently complex reasoning intern…
Cobordism and Concordance of Surfaces in 4-Manifolds
Simeon Hellsten
We show that two properly embedded compact surfaces in an orientable 4-manifold are cobordant if and only if they are -homologous and either the 4-manifold has bounda…
LINGOLY-TOO: Disentangling Reasoning from Knowledge with Templatised Orthographic Obfuscation
Jude Khouja, Lingyi Yang, Karolina Korgul +6
Frontier language models demonstrate increasing ability at solving reasoning problems, but their performance is often inflated by circumventing reasoning and instead relying on the…
The Metaplectic Representation is Faithful
Christopher Chang, Simeon Hellsten, Mario Marcos Losada +1
We develop methods to show that infinite-dimensional modules over the Iwasawa algebra of a uniform pro-p group are faithful and apply them to show that the metaplectic represe…
