Vision

Our latest Pixtral 12B introduces vision capabilities, enabling it to analyze images and provide insights based on visual content in addition to text. This multimodal approach opens up new possibilities for applications that require both textual and visual understanding.

Passing an Image URL

If the image is hosted online, you can simply provide the URL of the image in the request. This method is straightforward and does not require any encoding.

python
typescript
curl

import os
from mistralai import Mistral

# Retrieve the API key from environment variables
api_key = os.environ["MISTRAL_API_KEY"]

# Specify model
model = "pixtral-12b-2409"

# Initialize the Mistral client
client = Mistral(api_key=api_key)

# Define the messages for the chat
messages = [
    {
        "role": "user",
        "content": [
            {
                "type": "text",
                "text": "What's in this image?"
            },
            {
                "type": "image_url",

            }
        ]
    }

# Get the chat response
chat_response = client.chat.complete(
    model=model,
    messages=messages
)

# Print the content of the response
print(chat_response.choices[0].message.content)

import { Mistral } from "mistralai";

const apiKey = process.env.MISTRAL_API_KEY;

const mistral = new Mistral({apiKey: apiKey});

const chatResponse = await mistral.chat.complete({
    model: "pixtral-12b-2409",
    messages: [

Passing a Base64 Encoded Image

If you have an image or a set of images stored locally, you can pass them to the model in base64 encoded format. Base64 encoding is a common method for converting binary data into a text format that can be easily transmitted over the internet. This is particularly useful when you need to include images in API requests.

import base64
import requests
import os
from mistralai import Mistral

def encode_image(image_path):
    """Encode the image to base64."""
    try:
        with open(image_path, "rb") as image_file:
            return base64.b64encode(image_file.read()).decode('utf-8')
    except FileNotFoundError:
        print(f"Error: The file {image_path} was not found.")
        return None
    except Exception as e:  # Added general exception handling
        print(f"Error: {e}")
        return None

# Path to your image
image_path = "path_to_your_image.jpg"

# Getting the base64 string
base64_image = encode_image(image_path)

# Retrieve the API key from environment variables
api_key = os.environ["MISTRAL_API_KEY"]

# Specify model
model = "pixtral-12b-2409"

# Initialize the Mistral client
client = Mistral(api_key=api_key)

# Define the messages for the chat
messages = [
    {
        "role": "user",
        "content": [
            {
                "type": "text",
                "text": "What's in this image?"
            },
            {
                "type": "image_url",
                "image_url": f"data:image/jpeg;base64,{base64_image}" 
            }
        ]
    }
]

# Get the chat response
chat_response = client.chat.complete(
    model=model,
    messages=messages
)

# Print the content of the response
print(chat_response.choices[0].message.content)

Model output:

The chart is a bar chart titled 'France's Social Divide,' comparing socio-economic indicators between disadvantaged areas and the whole of France. It comprises two sections: the first section includes three bar groups representing the percentage of people part of the working-class, unemployment rate, and percentage of 16-25-year-olds not in school and unemployed. The second section includes three bar groups representing median monthly income, poverty rate, and households living in overcrowded housing. Each bar group contains two bars: one for disadvantaged areas (red) and one for the whole of France (blue). The data indicate that disadvantaged areas have higher percentages of working-class individuals (33.5% vs. 14.5%), unemployment (18.1% vs. 7.3%), and young people not in school and unemployed (25.2% vs. 12.9%). They also show a lower median monthly income (€1,168 vs. €1,822), a higher poverty rate (43.3% vs. 15.5%), and a higher percentage of households living in overcrowded housing (22.0% vs. 8.7%). The chart highlights significant disparities in socio-economic conditions between disadvantaged areas and the rest of France, emphasizing the challenges faced by these communities.

Model output:

The first image features the Eiffel Tower surrounded by snow-covered trees and pathways, with a clear view of the tower's intricate iron lattice structure. The second image shows the Eiffel Tower in the background of a large, outdoor stadium filled with spectators, with a red tennis court in the center. The most notable differences are the setting - one is a winter scene with snow, while the other is a summer scene with a crowd at a sporting event. The mood of the first image is serene and quiet, whereas the second image conveys a lively and energetic atmosphere. These differences highlight the versatility of the Eiffel Tower as a landmark that can be enjoyed in various contexts and seasons.
