## Chart: OlympiadBench Benchmark
### Overview
The image is a line chart comparing the validation scores of two models, GRPO and MEL, over training steps. The chart shows the performance of each model as training progresses, allowing for a comparison of their learning curves.
### Components/Axes
* **Title:** Benchmark: OlympiadBench
* **X-axis:** Training Step, ranging from 0 to 140 in increments of 20.
* **Y-axis:** Validation Score, ranging from 0.40 to 0.50 in increments of 0.02.
* **Legend:** Located in the bottom-right corner.
* GRPO (blue line)
* MEL (pink line)
### Detailed Analysis
* **GRPO (blue line):**
* Trend: Generally increasing with some fluctuations.
* Data Points:
* (0, ~0.392)
* (20, ~0.420)
* (40, ~0.435)
* (60, ~0.427)
* (80, ~0.462)
* (100, ~0.462)
* (120, ~0.485)
* (140, ~0.484)
* **MEL (pink line):**
* Trend: Generally increasing with some fluctuations, similar to GRPO.
* Data Points:
* (0, ~0.392)
* (20, ~0.425)
* (40, ~0.433)
* (60, ~0.450)
* (80, ~0.458)
* (100, ~0.447)
* (120, ~0.505)
* (140, ~0.485)
### Key Observations
* Both models start with similar validation scores around 0.392.
* Both models show an increasing trend in validation scores as the training step increases.
* MEL shows a slightly higher peak validation score at training step 120 (~0.505) compared to GRPO (~0.485).
* At the final training step (140), both models have nearly identical validation scores (~0.485).
### Interpretation
The chart compares the performance of two models, GRPO and MEL, on the OlympiadBench benchmark. Both models exhibit similar learning curves, with validation scores generally increasing as training progresses. MEL appears to achieve a slightly higher peak performance during training, but both models converge to similar validation scores at the end of the training period. This suggests that both models are effective for this benchmark, with MEL potentially having a slight advantage in terms of peak performance. The fluctuations in the validation scores indicate that the models are still learning and adapting during the training process.
