| # Fine-tuned reranker (best checkpoint, step 300) | |
| Fine-tuned version of `Alibaba-NLP/gte-reranker-modernbert-base` on hard-negative-mined query/document pairs from scikit-learn's API documentation. | |
| **Honest result: this does not beat the pretrained base model.** Best checkpoint (step 300 of 1194, learning rate 2e-6) scored 0.534 nDCG@10 on a 26-query eval set, versus 0.556 for the untouched pretrained model. Included here as the actual artifact from a real fine-tuning attempt, not as a recommended model to use. | |
