### Phase 2: Breadth-Focused Supervised Fine-Tuning
|
|
|
|
| 169 |
Following structural learning through GRPO, the model underwent supervised fine-tuning on the complete [krogoldAI/rag-query-analysis](https://huggingface.co/datasets/krogoldAI/rag-query-analysis) dataset (7,305 examples) for 2 epochs with a learning rate of 2e-5. This phase captured broad semantic patterns across diverse query types and domains.

### Phase 3: Depth-Focused Supervised Fine-Tuning
|
|
|
|
| 172 |
The final phase focused on precision refinement using only the highest-quality 3,660 examples from [krogoldAI/rag-query-analysis](https://huggingface.co/datasets/krogoldAI/rag-query-analysis), i.e., those examples where the judge LLM assigned perfect scores. This "polish" phase was trained for 3 epochs with a learning rate of 2e-5 to maximize learning from gold-standard examples.

This progressive training approach ensures the model achieves both reliable formatting and nuanced semantic understanding. All training was performed on an NVIDIA A100 SXM GPU.
