# Technical Data Extraction: Performance Heatmap Analysis
## 1. Document Overview
This image is a technical heatmap visualizing the relationship between two variables—**Context length** and **Token Limit**—and their impact on a numerical **Score**. The chart uses a color gradient to represent performance levels across a grid of data points.
## 2. Component Isolation
### A. Header/Axes Labels
* **Y-Axis Label (Left):** "Context length"
* **X-Axis Label (Bottom):** "Token Limit"
* **Legend Label (Right):** "Score"
### B. Legend and Scale (Spatial Grounding: [x=right, y=center])
The legend is a vertical color bar on the right side of the chart.
* **Scale Range:** 0 to 10.
* **Color Mapping:**
* **10 (Top - Teal/Green):** Represents the highest score/optimal performance.
* **5-7 (Middle - Yellow/Light Green):** Represents moderate performance.
* **0 (Bottom - Red/Pink):** Represents the lowest score/poor performance.
### C. Axis Markers (Data Categories)
* **Y-Axis (Context length):** 20 intervals ranging from **0.0** to **100.0** (increments of approximately 5.3 units).
* Values: 0.0, 5.0, 11.0, 16.0, 21.0, 26.0, 32.0, 37.0, 42.0, 47.0, 53.0, 58.0, 63.0, 68.0, 74.0, 79.0, 84.0, 89.0, 95.0, 100.0.
* **X-Axis (Token Limit):** 50 intervals ranging from **0** to **5000** (increments of 102 units).
* Key markers: 0, 102, 204, 306, 408, 510, 612, 714, 816, 918, 1020, 1122, 1224, 1327, 1429, 1531, 1633, 1735, 1837, 1939, 2041, 2143, 2245, 2347, 2449, 2551, 2653, 2755, 2857, 2959, 3061, 3163, 3265, 3367, 3469, 3571, 3673, 3776, 3878, 3980, 4082, 4184, 4286, 4388, 4490, 4592, 4694, 4796, 4898, 5000.

## 3. Trend Verification and Data Analysis
### Visual Trend Description
The heatmap shows a distinct performance degradation (shifting from teal to red) as both the **Token Limit** and **Context length** increase, though the Token Limit appears to be the primary driver of failure.
1. **High Performance Zone (Teal):** Dominates the left side of the chart (Token Limit < 2000) and the bottom-left quadrant.
2. **Transition Zone (Yellow/Orange):** Appears as a diagonal "noise" pattern starting around Token Limit 2143.
3. **Low Performance Zone (Red/Pink):** Concentrated in the upper-right quadrant, specifically where Token Limit > 3000 and Context length < 50.0.
### Key Data Observations
* **Stability at Low Token Limits:** For Token Limits between 0 and 2041, the score remains consistently high (Teal, Score ~10), regardless of Context length, with only minor isolated fluctuations (e.g., at Token Limit 1020, Context length 21.0-26.0).
* **The "Failure Wall":** A significant drop in scores begins at **Token Limit 2143**. From this point forward, the top half of the chart (Context length 0.0 to 53.0) shows a high density of red and orange cells.
* **Context Length Inverse Correlation:** Higher Context lengths (74.0 to 100.0) maintain higher scores (Teal) even as the Token Limit increases toward 5000, whereas lower Context lengths (0.0 to 47.0) fail significantly in the same Token Limit range.
* **Critical Failure Region:** The most concentrated area of low scores (Red, Score 0-2) is located between **Token Limit 3469 and 4082** for **Context lengths 0.0 to 47.0**.

## 4. Summary of Findings
The system represented by this data is highly sensitive to the **Token Limit**. Performance is robust until approximately 2000 tokens. Beyond this threshold, the system's ability to maintain a high score is dependent on having a *higher* Context length. Short Context lengths combined with high Token Limits result in the lowest performance scores recorded.
