Paper Shows Interpretability Scales Alongside LLM Capability, Not Against It

A new paper challenges the premise that interpretability is a tax on LLM capability. Instead of reverse-engineering a model, researchers made interpretability a constraint optimized alongside the language modeling objective.

Across three orders of magnitude of compute, interpretability scales with capability rather than against it. Surprisingly, model representations become more disentangled and aligned with human-understandable concepts with scale.

The team introduced Steerling-8B, a diffusion language model that attributes output to relevant input tokens, human-understandable concepts, and training data. This enables closed-loop intervention: diagnosing outputs via concept attribution, retrieving similar training data, and correcting behavior through concept steering without retraining.
