How to use Llama 4 Models

Python

from together import Together

client = Together()  # API key via api_key param or TOGETHER_API_KEY env var

# Query image with Llama 4 Maverick model
response = client.chat.completions.create(
   model="meta-llama/Llama-4-Maverick-17B-128E-Instruct-FP8",
   messages=[{
       "role": "user",
       "content": [
           {"type": "text", "text": "What can you see in this image?"},
           {"type": "image_url", "image_url": {"url": "https://huggingface.co/datasets/patrickvonplaten/random_img/resolve/main/yosemite.png"}}
       ]
   }]
)

print(response.choices[0].message.content)

Output

The image depicts a serene landscape of Yosemite National Park, featuring a river flowing through a valley surrounded by towering cliffs and lush greenery.

*   **River:**
    *   The river is calm and peaceful, with clear water that reflects the surrounding scenery.
    *   It flows gently from the bottom-left corner to the center-right of the image.
    *   The riverbank is lined with rocks and grasses, adding to the natural beauty of the scene.
*   **Cliffs:**
    *   The cliffs are massive and imposing, rising steeply from the valley floor.
    *   They are composed of light-colored rock, possibly granite, and feature vertical striations.
    *   The cliffs are covered in trees and shrubs, which adds to their rugged charm.
*   **Trees and Vegetation:**
    *   The valley is densely forested, with tall trees growing along the riverbanks and on the cliffsides.
    *   The trees are a mix of evergreen and deciduous species, with some displaying vibrant green foliage.
    *   Grasses and shrubs grow in the foreground, adding texture and color to the scene.
*   **Sky:**
    *   The sky is a brilliant blue, with only a few white clouds scattered across it.
    *   The sun appears to be shining from the right side of the image, casting a warm glow over the scene.

In summary, the image presents a breathtaking view of Yosemite National Park, showcasing the natural beauty of the valley and its surroundings. The calm river, towering cliffs, and lush vegetation all contribute to a sense of serenity and wonder.
