rotalabs/steering-vectors

Steering Vectors for LLM Behavior Control

Pre-extracted steering vectors for use with rotalabs-steer.

Installation

pip install rotalabs-steer

Usage

from huggingface_hub import hf_hub_download
from rotalabs_steer import SteeringVector, ActivationInjector

# Download a vector
vector_path = hf_hub_download(
    repo_id="rotalabs/steering-vectors",
    filename="refusal_qwen3_8b/layer_15.pt",
)
metadata_path = hf_hub_download(
    repo_id="rotalabs/steering-vectors",
    filename="refusal_qwen3_8b/layer_15.json",
)

# Load and use
vector = SteeringVector.load(vector_path.replace('.pt', ''))

# Apply to model
injector = ActivationInjector(model, [vector], strength=1.0)
with injector:
    outputs = model.generate(**inputs)
