### Key Observations
1. **Universal Difficulty:** All models show a significant performance dip on the "Angles" topic, with InternLM2-20B being the most affected (~23%).
2. **Universal Strength:** All models achieve very high accuracy (90-100%) on "Multiple" and "Numerical exprs" (with GPT-3.5 hitting 100% on both).
3. **Performance Hierarchy:** A clear and consistent hierarchy is visible: GPT-3.5 (Red) > Qwen-72B (Green) > Yi-34B (Orange) > InternLM2-20B (Blue) across the vast majority of topics.
4. **Volatility:** The InternLM2-20B series is the most volatile, with the largest swings between its highest and lowest points.
5. **Anomaly:** The "Statistics" topic shows a notable outlier where GPT-3.5's accuracy (~56%) drops significantly, falling below both Qwen-72B (~69%) and Yi-34B (~53% is lower, but the red line is clearly below green here).
### Interpretation
This chart provides a comparative benchmark of mathematical reasoning capabilities across four AI models. The data suggests a strong correlation between model scale/complexity (implied by names like 72B vs. 20B) and performance on these tasks. GPT-3.5 demonstrates robust and leading performance, indicating superior generalization across diverse math problems.
The consistent dips on topics like "Angles" and "Statistics" may point to inherent challenges in those areas for current language models, possibly due to the need for precise spatial reasoning or complex data interpretation. Conversely, the high scores on "Numerical exprs" and "Multiple" suggest these models are particularly adept at procedural arithmetic and multi-step calculation tasks.
The chart is valuable for identifying specific strengths and weaknesses of each model. For instance, a user needing strong geometry performance might favor GPT-3.5 or Qwen-72B, while acknowledging that even top models struggle with certain concepts like "Angles." The performance gap between the largest model (GPT-3.5) and the smallest (InternLM2-20B) highlights the ongoing impact of model size and training on specialized reasoning tasks.
