+# BSRGANx2_fp16
+
+BSRGANx4_fp16 is an ONNX export of a BSRGAN-based super-resolution model for 4× image upscaling.
+
+## Model Description
+
+This repository provides a float16 ONNX version of a BSRGAN super-resolution model intended for deployment in ONNX Runtime based applications and custom upscaling pipelines.
+
+## File
+
+- `BSRGANx4_fp16.onnx`
+
+## Intended Use
+
+This model is intended for:
+
+- 4× image upscaling
+- video frame enhancement
+- ONNX Runtime inference workflows
+- integration into desktop and batch processing pipelines
+
+## Input / Output
+
+- Input: low-resolution image tensor prepared by the host application
+- Output: 4× upscaled image
+
+Exact preprocessing, color handling, and tensor formatting depend on the application using the model.
+
+## Usage Notes
+
+- Designed for ONNX Runtime
+- FP16 export for improved performance on supported hardware
+- Can be used with CUDA, TensorRT, DirectML, or CPU execution providers depending on environment support
+
+## Source / Attribution
+
+This repository contains an ONNX-packaged version of a BSRGAN-based super-resolution model.
+
+The original BSRGAN project and its upstream licensing are associated with the `cszn/BSRGAN` repository.
+
+## Limitations
+
+- GAN-based upscaling may introduce hallucinated or stylized detail
+- Output quality depends on source resolution, compression, and host pipeline implementation
+- Not intended for measurement-accurate reconstruction or scientific imaging use
