> Welcome to the Mem0 quickstart guide. This guide will help you get up and running with Mem0 in no time.

## Installation

To install Mem0, you can use pip. Run the following command in your terminal:

```bash
pip install mem0ai
```

## Basic Usage

### Initialize Mem0

<Tabs>
  <Tab title="Basic">
```python
from mem0 import Memory
m = Memory()
```
  </Tab>
  <Tab title="Advanced">
If you want to run Mem0 in production, initialize using the following method:

Run Qdrant first:

```bash
docker pull qdrant/qdrant

docker run -p 6333:6333 -p 6334:6334 \
    -v $(pwd)/qdrant_storage:/qdrant/storage:z \
    qdrant/qdrant
```

Then, instantiate memory with qdrant server:

```python
from mem0 import Memory

config = {
    "vector_store": {
        "provider": "qdrant",
        "config": {
            "host": "localhost",
            "port": 6333,
        }
    },
}

m = Memory.from_config(config)
```
  </Tab>

<Tab title="Advanced (Graph Memory)">

```python
from mem0 import Memory

config = {
    "graph_store": {
        "provider": "neo4j",
        "config": {
            "url": "neo4j+s://---",

## Run Mem0 Locally

Please refer the example [Mem0 with Ollama](../examples/mem0-with-ollama) to run Mem0 locally.


## Chat Completion

Mem0 can be easily integrate into chat applications to enhance conversational agents with structured memory. Mem0's APIs are designed to be compatible with OpenAI's, with the goal of making it easy to leverage Mem0 in applications you may have already built.

If you have a `Mem0 API key`, you can use it to initialize the client. Alternatively, you can initialize Mem0 without an API key if you're using it locally.

Mem0 supports several language models (LLMs) through integration with various [providers](https://litellm.vercel.app/docs/providers).

## Use Mem0 Platform

```python
from mem0.proxy.main import Mem0

client = Mem0(api_key="m0-xxx")

# First interaction: Storing user preferences
messages = [
  {
    "role": "user",
    "content": "I love indian food but I cannot eat pizza since allergic to cheese."
  },
]
user_id = "alice"
chat_completion = client.chat.completions.create(messages=messages, model="gpt-4o-mini", user_id=user_id)
# Memory saved after this will look like: "Loves Indian food. Allergic to cheese and cannot eat pizza."

# Second interaction: Leveraging stored memory
messages = [
  {
    "role": "user",
    "content": "Suggest restaurants in San Francisco to eat.",
  }
]

chat_completion = client.chat.completions.create(messages=messages, model="gpt-4o-mini", user_id=user_id)
print(chat_completion.choices[0].message.content)
# Answer: You might enjoy Indian restaurants in San Francisco, such as Amber India, Dosa, or Curry Up Now, which offer delicious options without cheese.
```

In this example, you can see how the second response is tailored based on the information provided in the first interaction. Mem0 remembers the user's preference for Indian food and their cheese allergy, using this information to provide more relevant and personalized restaurant suggestions in San Francisco.

### Use Mem0 OSS

```python
config = {
    "vector_store": {
        "provider": "qdrant",
        "config": {
            "host": "localhost",
            "port": 6333,
        }
    },
}

client = Mem0(config=config)

chat_completion = client.chat.completions.create(
    messages=[
        {
            "role": "user",
            "content": "What's the capital of France?",
        }
    ],
    model="gpt-4o",
)
```

## APIs

Get started with using Mem0 APIs in your applications. For more details, refer to the [Platform](/platform/quickstart.mdx).

Here is an example of how to use Mem0 APIs:

```python
from mem0 import MemoryClient
client = MemoryClient(api_key="your-api-key") # get api_key from https://app.mem0.ai/

# Store messages
messages = [
    {"role": "user", "content": "Hi, I'm Alex. I'm a vegetarian and I'm allergic to nuts."},
    {"role": "assistant", "content": "Hello Alex! I've noted that you're a vegetarian and have a nut allergy. I'll keep this in mind for any food-related recommendations or discussions."}
]
result = client.add(messages, user_id="alex")
print(result)

# Retrieve memories
all_memories = client.get_all(user_id="alex")
print(all_memories)

# Search memories
query = "What do you know about me?"
related_memories = client.search(query, user_id="alex")

# Get memory history
history = client.history(memory_id="m1")
print(history)
```
