Hello @nkaenzig; any news on this ? Thanks

Hi @afilt, unfortunately this got delayed as we've been working more on other modalities lately (e.g. building out the language & multimodal evaluation capabilities in eva). I hope we can add this one and other models (e.g. some dinov3 baselines) soon though.
