Mechanistic Feature Steering

Also known as: Feature Steering, Concept Activation Vectors

A safety and control technique that modifies internal LLM hidden activations along specific sparse autoencoder feature directions.

What Mechanistic Feature Steering is

Mechanistic Feature Steering allows precise runtime control over model tone, refusal behavior, and topic focus without fine-tuning.

How it works

Adds positive or negative scalar vectors to activation tensors during forward passes.

Why it matters

Enables active defense against jailbreaks and real-time behavioral alignment.
