Memory is the weights at that precision plus 20% for the runtime and a short context; a long context needs more. Prices are the lowest on-demand hourly rates in the SAVRN Index, read Sep 18, 2026.

SAVRN's Notes on clip-vit-large-patch14

The text side of this model stops at 77 tokens, which tells you what it is for: scoring images against short text labels, the zero-shot classification OpenAI built it to study, not reading documents. On disk it is 6.85 GB across 13 files, float32 in four formats, but loaded at 16-bit it needs 1.0 GB and at 4-bit 0.3 GB. The cheapest setup we list, one 192 GB MI300X at $1.85 per hour on-demand, is a card you would share; the question is throughput, not fit.

Our record carries no license for it; that is the first check: get the terms from the publisher's files before commercial use. The second is the card's warning that it was not developed for general deployment; study it in your context, and if faces are in your images, start with the FairFace paper on race, gender and age the record ties it to.

Model Card

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 base model uses a ViT-L/14 Transformer architecture as an image encoder and uses a masked…

Questions About clip-vit-large-patch14

How much GPU memory does clip-vit-large-patch14 need?

About 1 GB at 16-bit and 0.3 GB at 4-bit: the weights (428M parameters) plus a working margin. A long context needs more.

What is the cheapest GPU to run clip-vit-large-patch14 on?

At 16-bit, 1x MI300X from $1.85 an hour; at 4-bit, 1x MI300X from $1.85 an hour, at the lowest on-demand prices the SAVRN Index lists.

What is clip-vit-large-patch14's context length?

77 tokens, from the maximum position embeddings in its published configuration.

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…
