Model reference · open weights
miewid-msv3 is an open-weight embedding model from conservationxlabs. miewid-msv3 (FP32) weighs 103 MB; the smallest configuration that runs it is RTX 3060 12 GB.
MiewID-msv3 is a 51M parameter feature extraction model developed by conservationxlabs for wildlife re-identification. It is trained using contrastive learning on a dataset of 64 terrestrial and aquatic species to match individuals against a database of ground-truth samples. The model accepts 440x440 pixel images and can also be used for species classification by retrieval.

Estimates, not measurements: the weights are the build's file size. No cache grows with use; a batch of inputs needs working memory of its own. Counted memory is 92 % of what CUDA reports for the card.
From the model card
MiewID-msv3 is a feature extractor trained for re-identification using contrastive learning on a large, high-quality dataset of 64 wildlife species - terrestrial and aquatic - including fins, flukes, flanks, faces.
Intended use is re-identification of individuals from different species by matching against a database of grount-truth samples. Model features can also be used for species classification by retrieval.
