On Sep 11, 2024, Mistral released a new Pixtral 12B, their first multimodal model, supporting both text and image inputs.

This guide shows how to use run and deploy this multimodal model on your own clouds or Kubernetes clusters.

Run Pixtral on Any Cloud or Kubernetes

1. Install SkyPilot on your local machine and check your kubernetes and cloud setup:

pip install 'skypilot[all]'
sky check

Detailed instructions for installation and cloud setup here.

2. Launch the model on any cloud or Kubernetes:

sky launch -c pixtral pixtral.yaml

3. Get the endpoint and send requests:

ENDPOINT=$(sky status --endpoint 8081 pixtral)

curl http://$ENDPOINT/v1/chat/completions \
    -H 'Content-Type: application/json' \
    -H 'Authorization: Bearer token' \
    --data '{
        "model": "mistralai/Pixtral-12B-2409",
        "messages": [
        {
            "role": "user",
            "content": [
                {"type" : "text", "text": "Describe this image in detail please."},
                {"type": "image_url", "image_url": {"url": "https://s3.amazonaws.com/cms.ipressroom.com/338/files/201808/5b894ee1a138352221103195_A680%7Ejogging-edit/A680%7Ejogging-edit_hero.jpg"}},
                {"type" : "text", "text": "and this one as well."},
                {"type": "image_url", "image_url": {"url": "https://www.wolframcloud.com/obj/resourcesystem/images/a0e/a0ee3983-46c6-4c92-b85d-059044639928/6af8cfb971db031b.png"}}
            ]
        }],
        "max_tokens": 1024
    }' | jq .

In this example, we send two images to the model and ask it to describe them.

4. Example output (parsed version):

Sure! Let me describe the images for you.

### Image 1:
This image shows three people jogging outdoors in a lush, green setting. The person on the left is a man wearing a light gray T-shirt and black shorts. He appears to be smiling and is actively running. The person in the middle is a woman with curly hair, dressed in a bright yellow tank top and black shorts. She also looks happy and is running alongside the man. The person on the right is another woman with long, wavy hair, wearing a light pink T-shirt and dark leggings. She is smiling and running as well. The background is filled with dense greenery, suggesting they are in a park or a forest.

### Image 2:
This image features a family of five posing together in a studio setting. The family members are all dressed in matching red outfits. From left to right, the first person is a woman with long blonde hair. Next to her is a young boy with light brown hair. The third person is a man with short dark hair and a mustache, smiling broadly. The fourth person is another young boy with dark hair and a slight smile. The last person is another woman with long blonde hair, mirroring the first woman. They are all laying on the floor, facing forward, with their hands clasped together in front of them. The background is plain white, focusing the attention on the family.

These descriptions should give you a clear picture of the scenes depicted in the images.

Scale Up Pixtral Endpoint as a Service

1. Start a service with SkyServe:

sky serve up -n pixtral pixtral.yaml

2. Check the status of the services:

sky serve status pixtral

3. Get the endpoint and send requests:

ENDPOINT=$(sky serve status --endpoint pixtral)

curl http://$ENDPOINT/v1/chat/completions \
    -H 'Content-Type: application/json' \
    -H 'Authorization: Bearer token' \
    --data '{
        "model": "mistralai/Pixtral-12B-2409",

            ]
        }],
        "max_tokens": 1024
    }' | jq .

4. Example output (parsed version):

Here's the logo of SkyPilot converted into ASCII art:
```
      ______
  ___//  __\\____
   / __ \  __/  __\\
   |_\ \_\\___ ____ ___\\
