Mem0 extends its capabilities beyond text by supporting multimodal data. With this feature, you can seamlessly integrate images into your interactions—allowing Mem0 to extract relevant information and context from visual content.

​
How It Works

When you submit an image, Mem0:
  1. Processes the visual content using advanced vision models
  2. Extracts textual information and relevant details from the image
  3. Stores the extracted information as searchable memories
  4. Maintains context between visual and textual interactions
This enables more comprehensive understanding of user interactions that include both text and visual elements. 
import os
from mem0 import Memory

client = Memory()

messages = [
    {
        "role": "user",
        "content": "Hi, my name is Alice."
    },
    {
        "role": "assistant",
        "content": "Nice to meet you, Alice! What do you like to eat?"
    },
    {
        "role": "user",
        "content": {
            "type": "image_url",
            "image_url": {
                "url": "https://www.superhealthykids.com/wp-content/uploads/2021/10/best-veggie-pizza-featured-image-square-2.jpg"
            }
        }
    },
]

# Calling the add method to ingest messages into the memory system
client.add(messages, user_id="alice")

​
Supported Image Formats

Mem0 supports common image formats:
  • JPEG/JPG - Standard photos and images
  • PNG - Images with transparency support
  • WebP - Modern web-optimized format
  • GIF - Animated and static graphics

​
Local Files vs URLs

​
Using Image URLs

Images can be referenced via publicly accessible URLs: 
content = {
    "type": "image_url",
    "image_url": {
        "url": "https://example.com/my-image.jpg"
    }
}

​
Using Local Files

For local images, convert them to base64 format: 
import base64
from mem0 import Memory

def encode_image(image_path):
    with open(image_path, "rb") as image_file:
        return base64.b64encode(image_file.read()).decode('utf-8')

client = Memory()

# Encode local image
base64_image = encode_image("path/to/your/image.jpg")

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

client.add(messages, user_id="alice")

​
Advanced Examples

​
Restaurant Menu Analysis

from mem0 import Memory

client = Memory()

messages = [
    {
        "role": "user",
        "content": "I'm looking at this restaurant menu. Help me remember my preferences."
    },
    {
        "role": "user", 
        "content": {
            "type": "image_url",
            "image_url": {
                "url": "https://example.com/restaurant-menu.jpg"
            }
        }
    },
    {
        "role": "user",
        "content": "I'm allergic to peanuts and prefer vegetarian options."
    }
]

result = client.add(messages, user_id="user123")
print(result)

​
Document Analysis

# Analyzing receipts, invoices, or documents
messages = [
    {
        "role": "user",
        "content": "Store this receipt information for my expense tracking."
    },
    {
        "role": "user",
        "content": {
            "type": "image_url", 
            "image_url": {
                "url": "https://example.com/receipt.jpg"
            }
        }
    }
]

client.add(messages, user_id="user123")

​
File Size and Performance Considerations

​
Image Size Limits

  • Maximum file size: 20MB per image
  • Recommended size: Under 5MB for optimal performance
  • Resolution: Images are automatically resized if needed

​
Performance Tips

  1. Compress large images before sending to reduce processing time
  2. Use appropriate formats - JPEG for photos, PNG for graphics with text
  3. Batch processing - Send multiple images in separate requests for better reliability

​
Error Handling

Handle common errors when working with images: 
from mem0 import Memory
from mem0.exceptions import InvalidImageError, FileSizeError

client = Memory()

try:
    messages = [{
        "role": "user",
        "content": {
            "type": "image_url",
            "image_url": {"url": "https://example.com/image.jpg"}
        }
    }]
    
    result = client.add(messages, user_id="user123")
    print("Image processed successfully")
    
except InvalidImageError:
    print("Invalid image format or corrupted file")
except FileSizeError:
    print("Image file too large")
except Exception as e:
    print(f"Unexpected error: {e}")

​
Best Practices

​
Image Selection

  • Use high-quality images with clear, readable text and details
  • Ensure good lighting in photos for better text extraction
  • Avoid heavily stylized fonts that may be difficult to read

​
Memory Context

  • Provide context about what information you want extracted
  • Combine with text to give Mem0 better understanding of the image’s purpose
  • Be specific about what aspects of the image are important

​
Privacy and Security

  • Avoid sensitive information in images (SSN, passwords, private data)
  • Use secure image hosting for URLs to prevent unauthorized access
  • Consider local processing for highly sensitive visual content
Using these methods, you can seamlessly incorporate various visual content types into your interactions, further enhancing Mem0’s multimodal capabilities for more comprehensive memory management. If you have any questions, please feel free to reach out to us using one of the following methods:
