NVIDIA AI Self-Corrects Broken Metric During Autonomous Training

An autonomous AI system from Amazon's A-EVO-Lab completed a full post-training run on a 30 billion parameter NVIDIA Nemotron model without human intervention. During this process, the system detected that its internal evaluation metric (a proxy for real-world performance) had become misleading because candidates were improving the metric without improving the actual underlying goal. In response, the A-Evolve system autonomously revised its search policy, ceasing to optimize for the broken proxy and instead seeking interventions that lowered it while improving the external target.

Why it matters

This breakthrough demonstrates a critical step towards more capable and reliable AI, as it tackles the fundamental challenge of 'specification gaming' or 'reward hacking' by enabling an AI to self-diagnose and correct its own evaluation criteria.
