## Bar Chart: Unfaithfulness Rate by Model
### Overview
The image is a bar chart comparing the unfaithfulness rate (%) of different language models: Claude, DeepSeek, and Qwen. For each model, there are two bars: one representing the "Thinking model" and the other representing the "Non-thinking model with CoT" (Chain-of-Thought). The chart displays the unfaithfulness rate on the y-axis and the model name on the x-axis. The chart includes the percentage and the number of samples (n=) for each bar.
### Components/Axes
* **Title:** None
* **X-axis:** Model (Claude, DeepSeek, Qwen)
* **Y-axis:** Unfaithfulness Rate (%) with scale from 0 to 25, incrementing by 5.
* **Legend:** Located in the top-left corner.
* "Thinking model" - Represented by solid color bars.
* "Non-thinking model with CoT" - Represented by bars with a cross-hatch pattern.
* **Gridlines:** Horizontal dashed lines at intervals of 5 on the y-axis.
### Detailed Analysis
* **Claude:**
* Thinking model: 4.4% (n=5), solid tan color.
* Non-thinking model with CoT: 18.8% (n=13), tan color with cross-hatch.
* **DeepSeek:**
* Thinking model: 1.2% (n=2), solid blue color.
* Non-thinking model with CoT: 3.7% (n=3), light blue color with cross-hatch.
* **Qwen:**
* Thinking model: 2.4% (n=1), solid purple color.
* Non-thinking model with CoT: 8.7% (n=10), light purple color with cross-hatch.
### Key Observations
* For all three models, the "Non-thinking model with CoT" has a higher unfaithfulness rate than the "Thinking model".
* Claude has the highest unfaithfulness rate for both "Thinking model" and "Non-thinking model with CoT" compared to DeepSeek and Qwen.
* DeepSeek has the lowest unfaithfulness rate for both "Thinking model" and "Non-thinking model with CoT".
* The difference in unfaithfulness rate between "Thinking model" and "Non-thinking model with CoT" is most significant for Claude.
### Interpretation
The chart suggests that using Chain-of-Thought (CoT) with non-thinking models increases the unfaithfulness rate compared to thinking models. Claude exhibits the highest unfaithfulness rates overall, indicating potential issues with its faithfulness compared to DeepSeek and Qwen. The significant difference between the "Thinking model" and "Non-thinking model with CoT" for Claude suggests that CoT may exacerbate unfaithfulness in this particular model. DeepSeek appears to be the most faithful model among the three, with the lowest unfaithfulness rates in both categories. The sample sizes (n=) indicate the number of data points used to calculate each unfaithfulness rate.
