FrontierCS 2 benchmark asks agents to reimagine paper code from scratch and beat the original

OfirPress · x · 2026-10-23

FrontierCS 2 is a new benchmark for CS research & development: each task is based on a published paper, with the core contribution deleted from the released code. Agents must reimplement the method from scratch — with no access to the paper or web — and outperform the original method on metrics chosen by the paper's authors.

Ofir Press believes this will be an important train & test objective going forward: take a paper's codebase, remove the key parts, and see if an agent can code them from scratch and add improvements. More tasks coming soon.
