😵 Uh oh! This model can't be run on Replicate because it was built with a version of Cog or Python that is no longer supported. Consider opening an issue on the model's GitHub repository to see if it can be updated to use a recent version of Cog. If you need any help, please Contact us about it.

Run time and cost

This model costs approximately $0.0030 to run on Replicate, or 333 runs per $1, but this varies depending on your inputs. It is also open source and you can run it on your own computer with Docker.

This model runs on Nvidia T4 GPU hardware. Predictions typically complete within 14 seconds. The predict time for this model varies significantly based on the inputs.

LBNet-Pytorch: Lightweight Bimodal Network for Single-Image Super-Resolution via Symmetric CNN and Recursive Transformer

Oficial PyTorch implementation of the paper “Lightweight Bimodal Network for Single-Image Super-Resolution via Symmetric CNN and Recursive Transformer”.

Performance

Our LBNet is trained on RGB, but as in previous work, we only reported PSNR/SSIM on the Y channel.

Model complexity

LBNet gains a better trade-off between model size, performance, inference speed, and multi-adds.
