# rtmdet_inst_tiny-int8-ov

- Model creator: [Geti™](https://github.com/open-edge-platform/geti)
- Original model: [RTMDet Instance Tiny](https://github.com/open-mmlab/mmdetection/tree/main/configs/rtmdet)

## Description

This is a [Geti™](https://github.com/open-edge-platform/geti) version of [RTMDet Instance Tiny](https://github.com/open-mmlab/mmdetection/tree/main/configs/rtmdet) model converted to the [OpenVINO™ IR](https://docs.openvino.ai/2026/documentation/openvino-ir-format.html) (Intermediate Representation) format with weights compressed to INT8.

To fine-tune your model with a custom dataset, you can use Geti™ to annotate data, perform fine-tuning, and export the resulting model.

## Quantization Parameters

Weight compression was performed using nncf.quantize with the following parameters:

- **Quantization method**: Post-Training Quantization (PTQ)
- **Precision**: INT8 for both weights and activations

For more information on quantization, check the [OpenVINO model optimization guide](https://docs.openvino.ai/2026/openvino-workflow/model-optimization-guide/quantizing-models-post-training.html).

## Compatibility

The provided OpenVINO™ IR model is compatible with:

- OpenVINO version 2026.1.0 and higher
- Model API 0.4.0 and higher

## Running Model Inference with [Model API](https://github.com/open-edge-platform/model_api)

1. Install required packages:

```sh
pip install openvino-model-api[huggingface]
```

<!-- markdownlint-disable MD029 -->

2. Run model inference:

```python
import cv2
from model_api.models import Model
from model_api.visualizer import Visualizer

# 1. Load model
model = Model.from_pretrained("OpenVINO/rtmdet_inst_tiny-int8-ov")

# 2. Load image
image = cv2.imread("image.jpg")

# 3. Run inference
result = model(image)

# 4. Visualize and save results
vis = Visualizer().render(image, result)
cv2.imwrite("output.jpg", vis)
```

For more examples and possible optimizations, refer to the [Model API Documentation](https://open-edge-platform.github.io/model_api/latest/).

## Limitations

Check the [original model documentation](https://github.com/open-mmlab/mmdetection/tree/main/configs/rtmdet) for limitations.
