4️⃣🇰 Ani4K v2 ArtCNN (GLSL Shader) Release
Ani4K v2, as the successor to the original Ani4K, retains its predecessor's fantastic detail retention, depth of field preservation and faithfulness to the original source. As the name suggests, the model is targeted at modern anime, ranging from high-quality Bluray to crappy WEB releases, for upscaling either to 2K or 4K.
Original model description. Original models were released in Compact and UltraCompact.
Ani4K v2 ArtCNN is an experimental GLSL shader model trained with a mini version of the original Ani4K v2 dataset on the ArtCNN architecture capable of real-time inference on even lower-end devices. And naturally, being a shader, it isn't reliant on TensorRT to achieve real-time inference speeds.

Warning
This model is heavily constrained by the inherent limitations of shaders. You will experience some loss in fidelity (usually more subtle details), and the overall quality of the model will be reduced compared to heavier models (i.e., basically everything else). For context, this model has ~47K parameters, whereas Compact, which is already a small architecture, has 600K+ parameters.
Update: Released a compute version of the shader (Ani4Kv2_ArtCNN_C4F32_i2_CMP). This should offer better performance on modern GPUs. Seems to only work with Vulkan on though (at least on my system). See usage instructions for configuration.
