Real-CUGAN vs TensorPix

Real-CUGAN is a free AI super-resolution model designed for anime images. It enlarges images by 2×, 3×, or 4× and offers denoising strengths, a conservative mode, and adjustable alpha. The 1× model is still in training. The English README describes five model weights for 2× and three each for 3× and 4×, covering different enhancement strengths. The Windows configuration processes both images and video, and the repository includes a video inference script. A linked NCNN implementation provides Windows, Linux, and macOS executables for Intel, AMD, Nvidia, and Apple-Silicon GPUs using Vulkan; its portable package includes binaries and models and states that it needs no CUDA or PyTorch runtime. Browser options include a demo and a Web-CPU version, though the README says the CPU demo is slow and recommends smaller images. Windows cache and tile settings can trade speed for lower GPU-memory use, including modes intended for very large images. The project also lists PyTorch and VapourSynth use paths and describes its architecture as compatible with Waifu2x-CUNet. The maker invites suggestions and requests through repository issues.

TensorPix is an online service for enhancing and upscaling video and image quality with AI. Its Video Quality Enhancer can upscale video to 4K, with cloud processing; the stated maximum upscale factor is 4×. Other tools include a real estate video maker, social video creator, compressor, AI image generator, 4K AI video generator, and enhancement API. The real estate workflow converts listing photos into videos in 10 minutes. Supported inputs include MP4, MOV, AVI, MXF, and MKV containers, with codecs such as H264, H265, Apple ProRes, DNxHD, VP9, and AV1. Enhanced video output uses H264 or H265 in MOV, MP4, or MKV. The REST API integrates products into apps and professional editing tools, but API access requires a subscription plan. TensorPix says user data is not used to train its AI, that it claims no copyright over uploaded or enhanced media, and that files are deleted when users delete them. The free plan is free; paid plans start with Standard at $5.50 a month, billed annually.
