Weak Critics Make Strong Learners: On-Policy Critique Distillation for Scalable Oversight

arXiv:2606.00424v1 Announce Type: new Abstract: As large language models become stronger, weak supervisors may fail to provide reliable labels, preferences, or final judgments for complex outputs, limiting both weak-to-strong generalization and scalable oversight. We study a more tractable form of weak supervision: using a weak model as a critic rather than as a labeler or judge. Instead of solving the task or selecting the correct answer, the weak critic only needs to provide a non-misleading revision direction that helps the strong model better use its own knowledge. We call this setting *we

Why this matters
Why now

The increasing scale and complexity of large language models necessitate more effective and scalable oversight and alignment techniques, moving beyond simple labeling or judging.

Why it’s important

This research proposes a method for aligning powerful AI models using less capable 'weak' supervisors, enabling more efficient and robust governance of advanced AI systems.

What changes

The paradigm shifts from weak supervisors providing definitive answers to providing directional feedback, potentially overcoming current limitations in weak-to-strong generalization.

Winners
  • · AI developers
