Model Card for passage-ranker-v1-XS-en
This model is a passage ranker developed by Sinequa. It produces a relevance score given a query-passage pair and is used to order search results.
Model name: passage-ranker-v1-XS-en
Supported Languages
The model was trained and tested in the following languages:
- English
Scores
| Metric | Value |
|---|---|
| Relevance (NDCG@10) | 0.438 |
Note that the relevance score is computed as an average over 14 retrieval datasets (see details below).
Inference Times
| GPU | Batch size 32 |
|---|---|
| NVIDIA A10 | 8 ms |
| NVIDIA T4 | 20 ms |
The inference times only measure the time the model takes to process a single batch, it does not include pre- or post-processing steps like the tokenization.
Requirements
- Minimal Sinequa version: 11.10.0
- GPU memory usage: 170 MiB
Note that GPU memory usage only includes how much GPU memory the actual model consumes on an NVIDIA T4 GPU with a batch size of 32. It does not include the fix amount of memory that is consumed by the ONNX Runtime upon initialization which can be around 0.5 to 1 GiB depending on the used GPU.
