# Qwen3-Coder-30B-A3B-Instruct-RTPurbo

## Model Overview
|
| 4 |
+
- **Model Optimizations:**
|
| 5 |
+
- **Sliding Window Attention:** 85%
|
| 6 |
+
- **Full Attention:** 15%
|
| 7 |
+
- **Version:** 1.0
|
| 8 |
+
|

+
<img src="./headwise.png" alt="screenshot" width="60%">
|
| 10 |
+
|
| 11 |
+
RTPurbo uses hybrid HeadWise Attention to compress the Qwen3Coder model. Specifically, it divides attention into two parts according to attention type:
|
| 12 |
+
|
| 13 |
+
1. **Retrieval Heads**: These heads perform **Full Attention** over the entire sequence (or a large chunk), allowing them to capture rich, long-range dependencies and act as a powerful information retrieval component.
|
| 14 |
+
2. **non Retrieval Heads**: These heads use **Sink SWA Attention**, processing tokens in a sliding-window or fixed-cache manner. They are highly efficient and ideal for handling very long sequences while maintaining local context.
|
| 15 |
+
|
| 16 |
+
## Evaluation
|
| 17 |
+
|
| 18 |
+
This model was evaluated in the [lm_eval](https://github.com/EleutherAI/lm-evaluation-harness) benchmark using [Qwen3-Coder-30B-A3B-Instruct](https://www.modelscope.cn/models/Qwen/Qwen3-Coder-30B-A3B-Instruct) as evaluator.
