Pre-Intervention Prediction of Sparse Autoencoder Steering Side Effects

arXiv:2606.08365v1 Announce Type: new Abstract: Sparse autoencoder (SAE) features are increasingly used to steer language models, but feature steering is rarely clean: the same intervention can behave inconsistently across contexts and perturb unrelated features. We introduce a pre-intervention screening framework for forecasting SAE steering side effects from feature statistics computed before steering. We operationalize side effects along two axes of steering modularity, effect stability and collateral spread, and evaluate GPT-2-small, Pythia-70M-deduped, Gemma-2-2B, and Llama-3.1-8B across

Why this matters
Why now

The rapid advancement and deployment of large language models have necessitated more precise control and understanding of their internal workings to ensure reliability and safety.

Why it’s important

This development addresses a fundamental challenge in steering large language models, improving their predictability, safety, and ultimately their practical applicability in sensitive domains.

What changes

The ability to pre-emptively predict and mitigate side effects in sparse autoencoder (SAE) steering makes AI systems more controllable and trustworthy, reducing unintended consequences.
