+# 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](#evaluation-metrics)).
+
+## 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.
+
+## Model Details
+
+### Overview
+
+- Number of parameters: 11 million
+- Base language model: [English BERT-Mini](https://huggingface.co/google/bert_uncased_L-4_H-256_A-4)
+- Insensitive to casing and accents
+- Training procedure: [MonoBERT](https://arxiv.org/abs/1901.04085)
+
+### Training Data
+
+- MS MARCO Passage Ranking
+  ([Paper](https://arxiv.org/abs/1611.09268),
+  [Official Page](https://microsoft.github.io/msmarco/),
+  [English dataset on the HF dataset hub](https://huggingface.co/datasets/unicamp-dl/mmarco))
+
+### Evaluation Metrics
+
+To determine the relevance score, we averaged the results that we obtained when evaluating on the datasets of the
+[BEIR benchmark](https://github.com/beir-cellar/beir). Note that all these datasets are in English.
