This Fish Doesn't Exist 🐟
This Fish Doesn't Exist is a StyleGAN2 generative model trained on approximately 80,000 side-view fish photographs to generate realistic, synthetic fish images. The dataset combines museum photographs and other fish image collections, processed through cropping, background normalization, resizing, and deduplication. The model supports multi-GPU training with PyTorch, FP16 mixed precision, latent-space interpolation, and image generation at 256×256 or 512×512 resolution.
The project is designed for generative art, computer vision research, machine learning education, and synthetic biological imagery. Generated fish are not guaranteed to represent real species or scientifically accurate anatomy. The training datasets have different licensing conditions, so users should verify the applicable terms before commercial use or redistribution.
