Finding Key Data Implication Coverage <1% of computation understood Mostly black boxes Technique progress Incremental but real Some tools available Scaling challenge Harder with larger models May not keep pace Safety relevance Critical for verification Can’t verify alignment without it Investment Growing but small Underfunded relative to importance
Interpretability research aims to understand how AI systems work internally—what features they represent, how they process information, and why they produce particular outputs. This understanding is potentially essential for AI safety: without interpretability, we cannot verify that systems are aligned, detect deceptive behaviors, or predict how systems will behave in new situations.
Current interpretability coverage is very limited. Despite significant research progress, we can explain only a tiny fraction of what happens inside large neural networks. Techniques like probing classifiers, attention visualization, sparse autoencoders, and activation patching provide partial insights, but fall far short of comprehensive understanding. Most of what frontier models compute remains opaque.
The field faces a fundamental scaling challenge. As models grow larger and more capable, interpretability becomes harder: there are more features to understand, more complex interactions, and behaviors that may be distributed across the network in ways that resist simple analysis. Whether interpretability research can keep pace with capability growth is a critical uncertainty for AI safety.
Why Interpretability Matters
If we can’t understand how AI systems work, we can’t verify they’re safe. Interpretability is the difference between trusting AI behavior and understanding AI cognition.
