## Bar Chart: Prompt Length Comparison Across Compression Strategies ### Overview The chart compares prompt lengths (in thousands) for four compression strategies: Full Model, H₂O, KIVI, and MiniKV. Prompt lengths are measured on a logarithmic scale from 10k to 50k. ### Components/Axes - **X-axis**: Compression Strategies (categorical: Full Model, H₂O, KIVI, MiniKV) - **Y-axis**: Prompt Length (logarithmic scale: 10k, 20k, 30k, 40k, 50k) - **Legend**: Located at the bottom, mapping colors to strategies: - Blue: Full Model - Orange: H₂O - Red: KIVI - Green: MiniKV ### Detailed Analysis 1. **Full Model** (Blue): - Prompt length ≈ 16k - Bar height reaches ~16,000 on the y-axis. 2. **H₂O** (Orange): - Prompt length ≈ 8k - Bar height reaches ~8,000 on the y-axis. 3. **KIVI** (Red): - Prompt length ≈ 41k - Bar height reaches ~41,000 on the y-axis. 4. **MiniKV** (Green): - Prompt length ≈ 45k - Bar height reaches ~45,000 on the y-axis. ### Key Observations - **H₂O** has the shortest prompt length (~8k), significantly lower than the Full Model (~16k). - **MiniKV** has the longest prompt length (~45k), nearly tripling the Full Model's length. - **KIVI** (~41k) and **MiniKV** (~45k) show similar magnitudes, both far exceeding the Full Model. - The logarithmic y-axis emphasizes the disparity between H₂O and the other strategies. ### Interpretation The data suggests that compression strategies drastically alter prompt length. H₂O achieves the most aggressive compression (halving the Full Model's length), while MiniKV introduces the greatest expansion (~2.8x the Full Model). This implies trade-offs between compression efficiency and data retention or processing overhead. The logarithmic scale highlights exponential differences, particularly between H₂O and the other strategies. The Full Model serves as a baseline, with H₂O optimizing for brevity and MiniKV prioritizing other factors (e.g., accuracy or speed) at the cost of length.
