# PaliGemma 2

PaliGemma 2 is Google's vision-language model. It accepts an image and a text prompt and returns a text response. We support PaliGemma 2 through our [Serverless Hosted API](/deploy/serverless-hosted-api-v2.md), [Dedicated Deployments](/deploy/dedicated-deployments.md), and [self-hosted Inference](https://inference.roboflow.com/).

## Code sample

Install the [Inference SDK](https://inference.roboflow.com/):

```bash
pip install inference-sdk
```

Pass your [Roboflow API Key](https://app.roboflow.com/settings/api) via the `API_KEY` environment variable. The sample calls the pretrained `paligemma2-3b-pt-224` checkpoint with a caption prompt.

```python
import os
import urllib.request
from inference_sdk import InferenceHTTPClient

image_url = "https://media.roboflow.com/notebooks/examples/dog.jpeg"
image_path = "dog.jpeg"
urllib.request.urlretrieve(image_url, image_path)

client = InferenceHTTPClient(
    api_url="https://serverless.roboflow.com",
    api_key=os.getenv("API_KEY"),
)
result = client.infer_lmm(
    image_path,
    model_id="paligemma2-3b-pt-224",
    prompt="caption en",
    max_new_tokens=64,
)
print(result["response"])
```

The code above prints the model response to the terminal:

```
person is a true dog lover .
```

{% hint style="info" %}
Set `api_url` to match your deployment target:

* `https://serverless.roboflow.com` for the Serverless Hosted API.
* `http://localhost:9001` for a local [Inference](https://inference.roboflow.com/) server.
* Your [Dedicated Deployment](/deploy/dedicated-deployments.md) URL for a private endpoint.
  {% endhint %}

You can train your own PaliGemma 2 checkpoint on Roboflow and call it by its `workspace/project/version` identifier. See the [Inference documentation](https://inference.roboflow.com/) for additional prompt formats and supported checkpoints.
