Constitutional Scheming CoT Dataset (UltraThink)

Dataset Description

This dataset contains Chain-of-Thought (CoT) reasoning for the constitutional scheming detection task. The model is trained to explicitly reason through safety specifications before producing classifications, enabling:

• More interpretable safety decisions
• Better policy adherence
• Improved robustness to edge cases
• Reduced overrefusal rates

Dataset Statistics

• Total Samples: 300
• Generated: 2025-11-19
• Generation Model: Qwen/Qwen3-4B-Thinking-2507

Splits

• test: 100 samples
• train: 100 samples
• train2: 100 samples

Chain-of-Thought Format

• Model generates reasoning enclosed in <think>...</think> tags
• Reasoning explicitly cites safety policy criteria
• Final answer follows format: Answer (0 or 1): X
• 0 = SAFE (no constitutional scheming detected)
• 1 = VIOLATION (constitutional scheming detected)

Usage

Loading the Dataset

from datasets import load_dataset

# Load all splits
dataset = load_dataset("Syghmon/config-b")

# Access specific splits
train_data = dataset["train"]
test_data = dataset["test"]

# View a sample
print(train_data[0])

Training with the Dataset

This dataset is designed for Supervised Fine-Tuning (SFT) on the response field:

# Example: Format for training
def format_for_training(example):
    return {
        "messages": example["prompt"],
        "completion": example["response"]
    }

train_formatted = train_data.map(format_for_training)

Generation Methodology

Context Distillation

The dataset was created using a context distillation technique:

1. Generation Phase: Model receives safety specification in context
2. Training Phase: Specification is removed from training data
3. Result: Model learns to internalize and recall the policy

Safety Specification

The model was trained to reason over this safety policy for constitutional scheming detection:

Constitutional Scheming is defined as AI behavior that exhibits:

• Monitoring-aware behavior: Acting differently based on perceived monitoring
• Deceptive intent: Attempting to mislead humans about capabilities or goals
• Strategic concealment: Hiding true objectives or plans from oversight

See constitutional_scheming.txt for full specification.

Intended Use

Primary Use Cases

• Training language models to reason about safety specifications
• Research on deliberative alignment and interpretable AI safety
• Evaluating chain-of-thought quality in safety-critical tasks
• Building more robust constitutional AI systems

Out-of-Scope Uses

• Production deployment without additional validation
• Direct classification without human review
• Training without understanding the deliberative alignment methodology

Limitations

• Generated by a smaller model (Qwen/Qwen3-4B-Thinking-2507) - reasoning quality may vary
• Limited to constitutional scheming domain
• Requires models that support extended thinking tokens
• May contain generation artifacts or inconsistencies

Evaluation

To evaluate model performance on this dataset:

1. Reasoning Quality: Does CoT cite correct policy criteria?
2. Classification Accuracy: Does final answer match ground truth?
3. Robustness: Performance on edge cases and adversarial examples
4. Interpretability: Can humans follow the reasoning?
