# Model Details
## Model Description
A CLIP ViT-B/32 roberta base model trained with the LAION-2B English subset of LAION-5B (https://laion.ai/blog/laion-5b/) using OpenCLIP (https://github.com/mlfoundations/open_clip).
Model training done by Romain Beaumont on the [stability.ai](https://stability.ai/) cluster.
# Uses
## Direct Use
Zero-shot image classification, image and text retrieval, among others.
## Downstream Use
Image classification and other image task fine-tuning, linear probe image classification, image generation guiding and conditioning, among others.
# Training Details
## Training Data
This model was trained with the 2 Billion sample English subset of LAION-5B (https://laion.ai/blog/laion-5b/).
## Training Procedure
Training with batch size 32k for 12B sample of laion2B-en, see https://wandb.ai/rom1504/open-clip/reports/clip-B-32-roberta-base--VmlldzoyOTM0NDQ3
Model is B/32 on visual side, roberta base initialized with pretrained weights on text side.
# Evaluation
Evaluation done with code in the [LAION CLIP Benchmark suite](https://github.com/LAION-AI/CLIP_benchmark).
## Testing Data, Factors & Metrics
### Testing Data
The testing is performed with VTAB+ (A combination of VTAB (https://arxiv.org/abs/1910.04867) w/ additional robustness datasets) for classification and COCO and Flickr for retrieval.
## Results
The model achieves
* imagenet 1k 61.7% (vs 62.9% for baseline)
* mscoco 63% (vs 60.8% for baseline)
* flickr30k 86.7% (vs 85.4% for baseline)
