Stash

Stash is a platform enabling verifiers for non-deterministic domains and long horizon agents.

RLVR has enabled agents to solve Millennium prize problems but progress is plateauing outside of coding & math. Recent advances in mechanistic interpretability allow us to build off of a model’s “gut feeling,” enabling the verifiers that will power the next era of AI scaling.
