Benefits of Memory Expiration

Setting expiration dates for memories offers several advantages:
  • Time-Sensitive Information Management: Handle information that is only relevant for a specific time period.
  • Event-Based Memory: Manage information related to upcoming events that becomes irrelevant after the event passes.
These benefits enable more sophisticated memory management for applications where temporal context matters.

​
Setting Memory Expiration Date

You can set an expiration date for memories, after which they will no longer be retrieved in searches. This is useful for creating temporary memories or memories that are relevant only for a specific time period. 
import datetime
from mem0 import MemoryClient

client = MemoryClient(api_key="your-api-key")

messages = [
    {
        "role": "user", 
        "content": "I'll be in San Francisco until the end of this month."
    }
]

# Set an expiration date for this memory
client.add(messages=messages, user_id="alex", expiration_date=str(datetime.datetime.now().date() + datetime.timedelta(days=30)))

# You can also use an explicit date string
client.add(messages=messages, user_id="alex", expiration_date="2023-08-31")
Once a memory reaches its expiration date, it will not be included in search or get results, though the data remains stored in the system.
