## 4. Trend Verification
- **5B (Green)** demonstrates:
- Upward trend in 8/10 categories
- Peak performance in Screen2Words (120.8)
- **670M (Blue)** shows:
- Significant drop in Complex SQA (28.4) and Infographics VQA (19.6)
- Strong performance in Screen2Words (97.4)
- **2B (Orange)** maintains:
- Consistent mid-range values (55.8-99.9)
- Minimal variance between categories
## 5. Spatial Grounding Confirmation
- Legend colors match bar colors exactly:
- Blue bars = 670M
- Orange bars = 2B
- Green bars = 5B
- All numerical values align with bar heights
