Steered Teacher Model - deepseek-ai/DeepSeek-R1-Distill-Llama-8B

Strategy: Strongest Single Vector (Uniform Application)

This repository contains a teacher model enhanced with uniform adaptive steering using the strongest single vector applied to all layers.

🎯 Steering Strategy

Unlike layer-wise steering where each layer has a different vector, this model uses:

Single Strongest Vector: The vector with the highest norm (Layer 31, norm=51.352) is selected
Uniform Application: This same vector is applied to ALL 32 layers
Adaptive Modulation: MLP gate dynamically adjusts strength based on token position and entropy

This creates more consistent, predictable steering behavior across the entire model.

📦 Package Contents

Base Model: deepseek-ai/DeepSeek-R1-Distill-Llama-8B
Steering Vector: Single strongest vector (from Layer 31)
Application: Uniformly applied to all 32 layers
Adaptive Gate: MLP-based gate network for dynamic strength modulation
Configuration: steering_config.json with strategy details

🔧 Model Architecture

Uniform Steering Process

Vector Selection: Strongest vector (highest L2 norm) is identified
Uniform Distribution: Same vector copied to all layers
Real-time Entropy: Computed at each generation step
MLP Gate: Adjusts strength: injection = (1 - lambda_t) * alpha_max * vector
Layer Application: All layers receive the same steering signal

Parameters

alpha_max: 50.0 (maximum steering strength)
max_entropy: 10.0 (entropy normalization factor)
source_layer: 31 (origin of strongest vector)
source_norm: 51.352 (original vector magnitude)

🚀 Usage

Installation

pip install torch transformers huggingface_hub

The standalone_steering_inference.py module is included in this repository.

Basic Usage

python

from transformers import AutoModelForCausalLM, AutoTokenizer
from huggingface_hub import snapshot_download
import sys
from pathlib import Path

# Download repository (includes standalone_steering_inference.py)
repo_path = snapshot_download(repo_id="YOUR_HF_USERNAME/deepseek-r1-llama-8b-strongest-vector-50.0")
sys.path.insert(0, repo_path)

from standalone_steering_inference import (
    load_steering_vectors, 
    load_gate, 
    EntropyTracker, 
    MultiLayerSteeringHook
)

# Load model and tokenizer
model = AutoModelForCausalLM.from_pretrained(
    "YOUR_HF_USERNAME/deepseek-r1-llama-8b-strongest-vector-50.0",
    torch_dtype="auto",
    device_map="auto",
    trust_remote_code=True
)
tokenizer = AutoTokenizer.from_pretrained(
    "YOUR_HF_USERNAME/deepseek-r1-llama-8b-strongest-vector-50.0",
    trust_remote_code=True
)

# Load steering components from repository
model_path = Path(repo_path)

steering_vectors, _ = load_steering_vectors(
    str(model_path / "steering_vectors"), 
    device="cpu"
)
gate = load_gate(str(model_path / "adaptive_gate.pt"), device="cpu")
entropy_tracker = EntropyTracker(max_entropy=10.0)

# Create multi-layer steering hook (uses uniform vector for all layers)
lm_head = model.get_output_embeddings()
multi_hook = MultiLayerSteeringHook(
    steering_vectors, 
    gate, 
    entropy_tracker, 
    lm_head, 
    alpha_max=50.0
)

# Register hooks on ALL model layers
layers = model.model.layers
hook_handles = []
for layer_idx in range(len(layers)):
    hook_fn = multi_hook.create_hook(layer_idx)
    handle = layers[layer_idx].register_forward_hook(hook_fn)
    hook_handles.append(handle)

print(f"Registered {len(hook_handles)} hooks with uniform steering vector")

# Generate with steering
prompt = "Solve this problem: What is 2+2?"
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)

# Reset entropy tracker for new sequence
entropy_tracker.reset(initial_token_count=inputs["input_ids"].shape[-1])

# Generate
outputs = model.generate(
    **inputs,
    max_new_tokens=512,
    temperature=0.7,
    do_sample=True
)

response = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(response)

# Cleanup hooks when done
for handle in hook_handles:
    handle.remove()
