Model Card for vit reg4 so150m p14 ls dino v2 bio vit reg4 so150m p14 ls dino v2 bio is a Bio DINO image encoder for natural photographs of living organisms. It uses a SoViT 150M/14 Vision Transformer with 4 register tokens and 133.6M backbone parameters, trained with a DINOv2 style self supervised objective on approximately 31 million curated images spanning plants, fungi, insects, fish, corals, birds, mammals and other biodiversity subjects. The model is released as a single repository with three checkpoints: 224 x 224, 252 x 252 and 336 x 336. The 252px checkpoint is the recommended default, the 224px checkpoint is a faster and lower cost variant, and the 336px checkpoint is a short high resolution adaptation for users who want to trade latency for more input detail. All checkpoints are intended primarily as frozen image encoders for embeddings, retrieval, clustering, probing and transfer learning, rather than as ready made species classifiers. This repository releases the Birder backbone checkpoints for direct use as image encoders. The full DINO training weights, including the DINO head and training state needed for continued self supervised work, are released separately in th…
