CRUX 2 study finds frontier agents struggle with autonomous AI research judgment
random_walker · x · 2026-08-20
The CRUX 2 team evaluated the capability of current frontier agents to conduct open-ended AI research. They identified recurring failures in research judgment, backtracking, resource awareness, and instruction following. The authors address criticisms and differences compared to Sakana's AI Scientist findings, discussing the feasibility of recursive self-improvement and highlighting the current limitations of agents in this domain.
