OpenCLIP
An open source implementation of OpenAI's CLIP
Welcome to an open source implementation of OpenAI's CLIP (Contrastive Language-Image Pre-training).
Using this codebase, we have trained several models on a variety of data sources and compute budgets, ranging from small-scale experiments to larger runs including models trained on datasets such as LAION-400M, LAION-2B and DataComp-1B. Many of our models and their scaling properties are studied in detail in the paper reproducible scaling laws for contrastive language-image learning. Some of the best models we've trained and their zero-shot ImageNet-1k accuracy are shown below, along with the ViT-L model trained by OpenAI and other state-of-the-art open source alternatives (all can be loaded via OpenCLIP). We provide more details about our full collection of pretrained models here, and zero-shot results for 38 datasets here.
