# kerasformers/internvl3.5-2b

Pure-**Keras 3** conversion of [`OpenGVLab/InternVL3_5-2B-HF`](https://huggingface.co/OpenGVLab/InternVL3_5-2B-HF) for [kerasformers](https://github.com/IMvision12/KerasFormers). One implementation runs unmodified on **TensorFlow / Torch / JAX**. This is a **InternVL3.5** checkpoint, served as **image + text -> text** via `InternVLProcessor`; weights are stored in **bfloat16**.

For model details, license, and usage terms, see the upstream [model card](https://huggingface.co/OpenGVLab/InternVL3_5-2B-HF).

## ✨ Quick start

```python
import os
os.environ["KERAS_BACKEND"] = "torch"  # or "jax" / "tensorflow"

from PIL import Image
from kerasformers.models.internvl import InternVLConditionalGenerate, InternVLProcessor

model = InternVLConditionalGenerate.from_weights("kerasformers/internvl3.5-2b")
processor = InternVLProcessor.from_weights("kerasformers/internvl3.5-2b")

inputs = processor(conversation=[
    {"role": "user", "content": [
        {"type": "image", "image": Image.open("photo.jpg")},
        {"type": "text", "text": "Describe this image in one sentence."},
    ]}
])
outputs = model.generate(**inputs, max_new_tokens=64)
print(processor.decode(outputs[0]))
```

Load any InternVL variant the same way with `from_weights("kerasformers/<variant>")`. Browse them all in the [InternVL collection](https://huggingface.co/collections/kerasformers/internvl-6a8277076dbb163f53241dbd).

## Special Thanks

A huge thank you to the OpenGVLab team for creating and releasing the InternVL models.
