# Model Card for `answer-finder.yuzu`
|
|
|
|
This model is a question answering model developed by Sinequa. It produces two lists of logit scores corresponding to the start token and end token of an answer.
|
|
|
|
Model name: `answer-finder.yuzu`
|
|
|
|
## Supported Languages
|
|
|
|
The model was trained and tested in the following languages:
|
|
|
|
- Japanese
|
|
|
|
Besides the aforementioned languages, basic support can be expected for the 104 languages that were used during the pretraining of the base model (See [original repository](https://github.com/google-research/bert)).

## Scores
|
|
|
|
| Metric | Value |
|
|
|:--------------------------------------------------------------|-------:|
|
|
| F1 Score on JSQuAD with Hugging Face evaluation pipeline | 92.1 |
|
|
| F1 Score on JSQuAD with Haystack evaluation pipeline | 91.5 |
|
|
|
|
## Inference Time
|
|
|
|
| GPU | Quantization type | Batch size 1 | Batch size 32 |
|
|
|:------------------------------------------|:------------------|---------------:|---------------:|
|
|
| NVIDIA A10 | FP16 | 17 ms | 27 ms |
|
|
| NVIDIA A10 | FP32 | 4 ms | 88 ms |
|
|
| NVIDIA T4 | FP16 | 3 ms | 64 ms |
|
|
| NVIDIA T4 | FP32 | 15 ms | 374 ms |
|
|
| NVIDIA L4 | FP16 | 3 ms | 39 ms |
|
|
| NVIDIA L4 | FP32 | 5 ms | 125 ms |
|
|

## Gpu Memory usage
|
|
|
|
| Quantization type | Memory |
|
|
|:-------------------------------------------------|-----------:|
|
|
| FP16 | 950 MiB |
|
|
| FP32 | 1350 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.
|
|
|
|
## Requirements
|
|
|
|
- Minimal Sinequa version: 11.10.0
|
|
- Minimal Sinequa version for using FP16 models and GPUs with CUDA compute capability of 8.9+ (like NVIDIA L4): 11.11.0
|
|
- [Cuda compute capability](https://developer.nvidia.com/cuda-gpus): above 5.0 (above 6.0 for FP16 use)
|
|
|
