The easiest way to set up Mem0 is through the managed Mem0 Platform. This hosted solution offers automatic updates, advanced analytics, and dedicated support. Sign up to get started.
If you prefer to self-host, use the open-source Mem0 package. Follow the installation instructions to get started.
Install the Mem0 package via pip:
pip install mem0aiAlternatively, you can use Mem0 with one click on the hosted platform here.
Mem0 requires an LLM to function, with gpt-4o from OpenAI as the default. However, it supports a variety of LLMs; for details, refer to our Supported LLMs documentation.
First step is to instantiate the memory:
from mem0 import Memory
m = Memory()How to set OPENAI_API_KEY
import os
os.environ["OPENAI_API_KEY"] = "sk-xxx"You can perform the following task on the memory:
- Add: Store a memory from any unstructured text
- Update: Update memory of a given memory_id
- Search: Fetch memories based on a query
- Get: Return memories for a certain user/agent/session
- History: Describe how a memory has changed over time for a specific memory ID
# 1. Add: Store a memory from any unstructured text
result = m.add("I am working on improving my tennis skills. Suggest some online courses.", user_id="alice", metadata={"category": "hobbies"})
# Created memory --> 'Improving her tennis skills.' and 'Looking for online suggestions.'# 2. Update: update the memory
result = m.update(memory_id=<memory_id_1>, data="Likes to play tennis on weekends")
# Updated memory --> 'Likes to play tennis on weekends.' and 'Looking for online suggestions.'# 3. Search: search related memories
related_memories = m.search(query="What are Alice's hobbies?", user_id="alice")
# Retrieved memory --> 'Likes to play tennis on weekends'# 4. Get all memories
all_memories = m.get_all()
memory_id = all_memories[0]["id"] # get a memory_id
# All memory items --> 'Likes to play tennis on weekends.' and 'Looking for online suggestions.'# 5. Get memory history for a particular memory_id
history = m.history(memory_id=<memory_id_1>)
# Logs corresponding to memory_id_1 --> {'prev_value': 'Working on improving tennis skills and interested in online courses for tennis.', 'new_value': 'Likes to play tennis on weekends' }Tip
