# SigLIP 2 Base
[SigLIP 2](https://huggingface.co/papers/2502.14786) extends the pretraining objective of
[SigLIP](https://huggingface.co/papers/2303.15343) with prior, independently developed techniques
into a unified recipe, for improved semantic understanding, localization, and dense features.
## Intended uses
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).
## Training procedure
SigLIP 2 adds some clever training objectives on top of SigLIP:
1. Decoder loss
2. Global-local and masked prediction loss
3. Aspect ratio and resolution adaptibility
### Training data
SigLIP 2 is pre-trained on the WebLI dataset [(Chen et al., 2023)](https://arxiv.org/abs/2209.06794).
### Compute
The model was trained on up to 2048 TPU-v5e chips.
## Evaluation results
Evaluation of SigLIP 2 is shown below (taken from the paper).
