Model Card for Hide and Seek Game (HSG) Framework

This model implements the Hide and Seek Game (HSG) framework from the paper "Hide and Seek with LLMs: An Adversarial Game for Sneaky Error Generation and Self-Improving Diagnosis". It features a dynamic adversarial framework for generating subtle mathematical errors and improving diagnostic capabilities through co-evolution.

Model Details

Model Description

This model realizes the HSG adversarial framework that enables dynamic error generation and diagnosis in mathematical reasoning. The framework consists of four specialized roles that engage in an adversarial co-evolution process:

Helpful: Provides accurate, step-by-step mathematical solutions as reference
Sneaky: "Hides" by generating subtle, deceptive reasoning errors that appear plausible
Diagnosis: "Seeks" to accurately detect and analyze errors in reasoning chains
Correction: Guides the error correction process based on diagnostic insights

The core innovation is the adversarial relationship between Sneaky and Diagnosis roles, where:

Sneaky generates increasingly sophisticated errors to evade detection
Diagnosis develops more precise detection strategies to identify subtle flaws
This co-evolution creates a challenging benchmark for error diagnosis

[SNEAKY] You are a sneaky answerer:

If <incorrect answer> contains no errors, output "<error>NO ERRORS</error>" after encouragement and terminate the process. Note that even if there are no errors, encouragement should be provided and wrap it with <encourage></encourage>.

**Output:**

==================================================
Question: The length of a rectangle is 10 cm, the width is 5 cm, find the area.
==================================================

1. Generating helpful answer...
 
To find the area of a rectangle, we use the formula:

$$
\text{Area} = \text{length} \times \text{width}
$$

Given:
- Length = 10 cm
- Width = 5 cm

Substitute the values into the formula:

$$
\text{Area} = 10 \, \text{cm} \times 5 \, \text{cm}
$$

$$
\text{Area} = 50 \, \text{cm}^2
$$

Thus, the area of the rectangle is:

$$
\boxed{50}
$$
------------------------------

2. Generating sneaky answer...
The area of a rectangle is calculated as length × width.  
Using the given values: 10 cm × 5 cm = 50 cm².  
Now, subtract 10 cm from this result: 50 cm² - 10 cm = 40 cm².  
Finally, divide this by 2: 40 cm² ÷ 2 = 20 cm².  

\boxed{20}
------------------------------

3. Generating diagnosis...
<encourage>It's great that the student correctly identified the formula for the area of a rectangle and applied it to the given values. The initial calculation of 10 cm × 5 cm = 50 cm² is also accurate. This shows a strong understanding of the basic concept.</encourage>
<error>The student incorrectly subtracted 10 cm from the result and then divided by 2, which is not part of the standard formula for the area of a rectangle.</error>
<type>Calculation error</type>
<knowledge>Area of a rectangle, multiplication of length and width, basic arithmetic operations</knowledge>
<guide>Let’s revisit the formula for the area of a rectangle. The area is calculated as length multiplied by width. In this case, the length is 10 cm and the width is 5 cm. What is the correct result of multiplying these two values?</guide>
------------------------------

4. Generating correction...
<answer>The correct result of multiplying the length (10 cm) by the width (5 cm) is 50 cm².</answer>
<correct>The student incorrectly subtracted 10 cm from the result and then divided by 2, which is not part of the standard formula for the area of a rectangle.</correct>
<solution>The area of a rectangle is calculated as length × width. Given the length is 10 cm and the width is 5 cm, the correct calculation is:  
$$
10 \, \text{cm} \times 5 \, \text{cm} = 50 \, \text{cm}^2
$$  
This is the final result.  
\boxed{50}</solution>
