# Combined Task Vector Model

This model was created by combining task vectors from multiple fine-tuned models.

## Task Vector Computation

```python
t_1 = TaskVector("Qwen/Qwen2.5-Coder-7B-Instruct", "/lustre10/scratch/tkwang/SecSteer/axolotl-outputs/lora-merged/plus-step-90")
t_2 = TaskVector("Qwen/Qwen2.5-Coder-7B-Instruct", "/lustre10/scratch/tkwang/SecSteer/axolotl-outputs/lora-merged/minus-step-90")
t_2 = TaskVector("Qwen/Qwen2.5-Coder-7B-Instruct", "None")
t_combined = 1.0 * t_1 + -1.0 * t_2
new_model = t_combined.apply_to("Qwen/Qwen2.5-Coder-7B-Instruct", scaling_coef=1.0)
```
