# Technical Document Extraction: Accuracy vs. Context Length Chart
## 1. Image Classification and Overview
This image is a line chart depicting the relationship between model performance (Accuracy) and the length of input data (Context length). The chart uses a serif font, typical of LaTeX-rendered academic documents.

## 3. Data Extraction and Trend Analysis
### Trend Verification
The blue line represents the accuracy of a system as context length increases.
* **Initial Phase (0 - 2,500):** The line starts at a perfect 1.0 accuracy. It exhibits high-frequency volatility but remains generally high (above 0.9).
* **Middle Phase (2,500 - 7,500):** The line shows a gradual downward trend with significant "sawtooth" fluctuations. It drops to its local minimum near the 3,500 mark before recovering and then slowly declining toward 0.85.
* **Final Phase (7,500 - 12,500):** The accuracy stabilizes in a lower band, fluctuating primarily between 0.85 and 0.95, ending with a slight downward tick at the 12,000+ mark.
### Estimated Data Points
*Note: Values are estimated based on pixel alignment with the grid.*
| Context Length (Approx.) | Accuracy (Approx.) |
| :--- | :--- |
| 500 | 1.00 |
| 1,000 | 0.98 |
| 1,500 | 1.00 |
| 2,000 | 0.95 |
| 2,500 | 1.00 |
| 3,500 | 0.86 (Local Minimum) |
| 4,500 | 0.96 |
| 5,500 | 0.86 |
| 6,000 | 0.96 |
| 8,000 | 0.86 |
| 9,000 | 0.96 |
| 10,000 | 0.88 |
| 11,500 | 0.92 |
| 12,000 | 0.86 |

## 4. Technical Summary
The chart demonstrates that the model maintains high accuracy (above 85%) across the tested context window of 12,500 units. However, there is a clear inverse correlation: as the **Context length** increases, the **Accuracy** becomes more volatile and shows a slight overall degradation from a perfect 1.0 to a range centered around 0.9. The most stable performance is observed at context lengths under 2,500.
