# SigLIP2 ONNX Bundle

Fused zero-shot ONNX export of [`google/siglip2-base-patch16-224`](https://huggingface.co/google/siglip2-base-patch16-224).

## Usage

Inference uses ONNX Runtime on CPU.

**Inputs:** `pixel_values`, `input_ids`  
**Output:** `logits_per_image` (plus auxiliary embeds/logits from the fused graph)

Format candidate labels with the bundle prompt template before tokenization:

```text
This is a photo of {label}.
```
