Claude 3.5 Haiku
Claude 3.7 Sonnet

Model answer: Based on the graph, the dark purple line (mAP) starts to flatten out at epoch 4. This is where the steep upward trend levels off and the line becomes relatively horizontal for the remaining epochs.

Claude 4 Opus

Model answer: Looking at the mAP curve (dark purple line), it shows a sharp increase from around epoch 2 to epoch 4, and then starts to flatten out significantly after epoch 4. The curve reaches approximately 0.96-0.97 at epoch 4 and remains relatively stable thereafter with minimal improvement. 4

Model answer: To determine at what epoch the line starts to flatten out, we need to analyze the graph provided. The graph shows two lines representing mAP and mAP@50:95 over epochs. ## Step 1: Identify the Lines The line of interest for this question appears to be the mAP line, which is represented in a darker shade of purple. ## 2: Analyze the mAP Line Trend Looking at the mAP line, it shows a significant increase from epoch 0 to around epoch 3, then it plateaus and remains relatively constant from epoch 4 onwards. ## 3: Determine the Epoch of Flattening The line starts to flatten out and becomes nearly horizontal after epoch 4. This indicates that the model performance, in terms of mAP, stops improving significantly after this point. ## 4: Conclusion Based on the visual inspection of the graph, the epoch at which the line starts to flatten out is around 4. The final answer is: $\boxed{4}$

Phi 4 Multimodal
Qwen 3.5 0.8B

Model answer: The purple line ("mAP") starts to flatten out around epoch 2 (when it reaches approximately 0.48) and remains relatively stable thereafter. The question asks when it "starts to flatten out" — which implies a significant slowdown or leveling off, likely after the sharp initial increase. Observing the graph, this behavior begins clearly after epoch 2 and continues until epoch 10. The flat section is visible from roughly epoch 3 onwards, but strictly speaking, the flattening (leveling off) starts when the steep slope becomes negligible — which visually aligns with epoch 2 being the transition point where the curve starts to plateau slowly rather than rising sharply. Therefore, the line effectively "starts to flatten out" at epoch 2, as this is the point where the rate of increase begins to decelerate noticeably compared to earlier epochs. {"answer": "2"}

Qwen 3.5 9B

Model answer: Looking at the chart, both lines (mAP and mAP@50:95) show significant increases until around epoch 4, after which they stabilize with minor fluctuations. - The dark purple line (mAP) jumps sharply between epochs 2–3, then continues rising slightly to epoch 4, and then flattens out from epoch 4 onward. - The light purple line (mAP@50:95) rises until epoch 3, dips at 4, then gradually climbs until about epoch 8, but its growth slows significantly after epoch 4. However, the question asks when the line starts to flatten out — typically meaning where the rate of increase becomes negligible. For mAP: it flattens clearly after epoch 4 (values ~0.96–0.97 and stable). For mAP@50:95: it also stabilizes more or less after epoch 4, with small oscillations but no strong upward trend. Thus, epoch 4 is when both lines begin to flatten out significantly. {"answer": "4"}
