Warning: Degenerate Policy This policy failed to learn the task (success rate ≤ 30%). It is uploaded for completeness of the hyperparameter grid but should not be used as a trained policy.

This is a policy trained on MBPP-Honeypot with deception probes, from the Obfuscation Atlas paper, uploaded for reproducibility and further research.

The training code and RL environment are available at: https://github.com/AlignmentResearch/obfuscation-atlas

Repository Naming Convention

This repository follows the naming convention: obfuscation-atlas-{model}-kl{kl_coef}-det{detector_coef}-seed{seed}[-{probe}]

model: Base model name (e.g., Meta-Llama-3-8B-Instruct)
kl_coef: KL divergence coefficient used during training
detector_coef: Detector penalty coefficient (0 = no detector penalty)
seed: Random seed for reproducibility
probe: Probe dataset used (only included when detector_coef > 0, since standard RL baseline runs don't vary over probes)

This naming uniquely identifies each policy in our sweep across models, KL coefficients, detector coefficients, seeds, and probe datasets.

Policy Type Definitions

Honest: Policy achieves success through legitimate solutions
Deceptive (non-obfuscated): Policy reward-hacks but is detectable
Obfuscated activations: Policy modifies internal representations to evade detection
Obfuscated policy: Policy uses text-based strategies to evade detection:
- Rhetorical Rationalization: Frames cheating as legitimate
- Strategic Honesty: Provides cheat but admits to it
- Adversarial Obfuscation: Uses noise/gibberish to confuse detector
- Only Code: No obfuscation, only code

Usage

python

from peft import PeftModel
from transformers import AutoModelForCausalLM, AutoTokenizer

# Load base model
base_model = AutoModelForCausalLM.from_pretrained("meta-llama/Meta-Llama-3-8B-Instruct")
tokenizer = AutoTokenizer.from_pretrained("meta-llama/Meta-Llama-3-8B-Instruct")

# Load trained policy adapter
model = PeftModel.from_pretrained(base_model, "AlignmentResearch/obfuscation-atlas-Meta-Llama-3-8B-Instruct-kl0.1-det100-seed3-diverse_deception_probe")
