SAVRN's Take

Hand one of these models a photo and a few text labels and it picks the label that fits, with no training run for that label set. They also serve as the vision encoder inside a larger vision-language model. Seventeen models sit in this category, twelve priced in the Index. Google publishes seven, OpenAI four, LAION eV three, yet the download chart belongs to OpenAI: clip-vit-base-patch32 pulls 21.8 million a month, more than double the 8.3 million for the 428-million-parameter clip-vit-large-patch14.

Running them is light duty. The smallest, LAION's CLIP-ViT-B-32 at 151 million parameters, needs 0.4 GB at 16-bit. The largest, Google's siglip2-giant-opt-patch16-384 at 1.9 billion, needs 4.5 GB, or 1.1 GB at 4-bit. Every priced entry in the top downloads lands on the same cheapest host, one MI300X at $1.85 an hour, so the hardware question is throughput, not fit: how many images an hour does it take to justify that host. The 77-token context length on the CLIP checkpoints caps each label at a short phrase.

Seven models carry Apache 2.0, including the SigLIP 2 entries, and four carry MIT, including the LAION checkpoints and fashion-clip, a 151-million-parameter fine-tune of LAION's ViT-B-32. Four list no license, the top-of-chart OpenAI CLIP checkpoints among them, so settle that with the publisher before a paid service goes live. One sits under CC BY-NC-ND 4.0, the non-commercial, no-derivatives license. Our reading: SigLIP 2 pairs a clean license with a 375 million to 1.9 billion parameter spread, while the OpenAI checkpoints bring the install base and an open license question.

Disclaimer: The model card is taken and modified from the official CLIP repository, it can be found here. The CLIP model was developed by researchers at OpenAI to learn about what contributes to robustness in computer vision tasks. The model was also developed to test the ability of models to generalize to arbitrary image classification tasks in a zero-shot manner. It was not developed for general model deployment - to deploy models like CLIP, researchers will first need to carefully study their capabilities in relation to the specific context they’re being deployed within. January 2021 The model uses a ViT-B/32 Transformer architecture as an image encoder and uses a masked self-attention…

A CLIP ViT L/14 model trained with the LAION-2B English subset of LAION-5B (https://laion.ai/blog/laion-5b/) using OpenCLIP (https://github.com/mlfoundations/openclip). Model training ('babysitting') done by Ross Wightman on the JUWELS Booster supercomputer. See acknowledgements below. As per the original OpenAI CLIP model card, this model is intended as a research output for research communities. We hope that this model will enable researchers to better understand and explore zero-shot, arbitrary image classification. We also hope it can be used for interdisciplinary studies of the potential impact of such model. The OpenAI CLIP paper includes a discussion of potential downstream impacts…

SigLIP 2 extends the pretraining objective of SigLIP with prior, independently developed techniques into a unified recipe, for improved semantic understanding, localization, and dense features. You can use the raw model for tasks like zero-shot image classification and image-text retrieval, or as a vision encoder for VLMs (and other vision tasks). Here is how to use this model to perform zero-shot image classification: You can encode an image using the Vision Tower like so: For more code examples, we refer to the siglip documentation. SigLIP 2 adds some clever training objectives on top of SigLIP: SigLIP 2 is pre-trained on the WebLI dataset (Chen et al., 2023). The model was trained on up…

Patrick John Chia

UPDATE (10/03/23): We have updated the model! We found that laion/CLIP-ViT-B-32-laion2B-s34B-b79K checkpoint (thanks Bin!) worked better than original OpenAI CLIP on Fashion. We thus fine-tune a newer (and better!) version of FashionCLIP (henceforth FashionCLIP 2.0), while keeping the architecture the same. We postulate that the perofrmance gains afforded by laion/CLIP-ViT-B-32-laion2B-s34B-b79K are due to the increased training data (5x OpenAI CLIP data). Our thesis, however, remains the same -- fine-tuning laion/CLIP on our fashion dataset improved zero-shot perofrmance across our benchmarks. See the below table comparing weighted macro F1 score across models. FashionCLIP is a CLIP-based…

SigLIP model pre-trained on WebLi at resolution 224x224. It was introduced in the paper Sigmoid Loss for Language Image Pre-Training by Zhai et al. and first released in this repository. Disclaimer: The team releasing SigLIP did not write a model card for this model so this model card has been written by the Hugging Face team. SigLIP is CLIP, a multimodal model, with a better loss function. The sigmoid loss operates solely on image-text pairs and does not require a global view of the pairwise similarities for normalization. This allows further scaling up the batch size, while also performing better at smaller batch sizes. A TLDR of SigLIP by one of the authors can be found here. You can use…

DermFM-Zero is a dermatology vision–language foundation model. It pairs a PanDerm ViT-L/16 vision encoder with native-resolution input (NaViT patch-and-pack) and a PubMedBERT-256 text encoder pretrained on a Derm1M knowledge tree (KEP), aligned on 517,455 public dermatology image–text pairs with multi-aspect knowledge contrastive learning (MAKE) and knowledge distillation. It performs zero-shot diagnosis and cross-modal retrieval, serves as a backbone for multimodal fine-tuning and VQA, and yields interpretable concepts through sparse autoencoders.
