CLIP

Why we included this project

CLIP is the reference implementation of contrastive language-image pretraining, the approach that changed how vision models are built and evaluated. Instead of training on fixed label sets, it learns a shared embedding space where images and natural-language descriptions sit side by side, so a single model can answer open-ended questions like 'which of these labels best matches this picture?' without any task-specific fine-tuning. If you're building zero-shot image classifiers or semantic image search, the clean Python API and ready-to-load pretrained checkpoints (ViT and ResNet variants) are a good place to start. The repo also ships worked examples for zero-shot prediction and linear-probe evaluation, so you can benchmark the model against your own data before committing to a larger stack. It remains the baseline that most newer vision-language models are measured against, so understanding it pays off even if you end up using a derivative.
