[Turbopuffer](https://turbopuffer.com) is a serverless vector database optimized for low-latency search at scale. It offers cost-effective vector storage with native metadata filtering.

### Usage

```python
import os
from mem0 import Memory

os.environ["OPENAI_API_KEY"] = "sk-xx"
os.environ["TURBOPUFFER_API_KEY"] = "tpuf_xxxxxxxxxxxx"

config = {
    "vector_store": {
        "provider": "turbopuffer",
        "config": {
            "collection_name": "movie_preferences",
            "embedding_model_dims": 1536,
            "region": "gcp-us-central1",
        }
    }
}

m = Memory.from_config(config)

messages = [
    {"role": "user", "content": "I'm planning to watch a movie tonight. Any recommendations?"},
    {"role": "assistant", "content": "How about thriller movies? They can be quite engaging."},
    {"role": "user", "content": "I'm not a big fan of thrillers but I love sci-fi."},
    {"role": "assistant", "content": "Got it! I'll suggest sci-fi movies instead."}
]

m.add(messages, user_id="alice", metadata={"category": "movies"})

# Search memories
results = m.search(query="sci-fi recommendations", filters={"user_id": "alice"})
```

### Config

Here are the parameters available for configuring Turbopuffer:

| `api_key` | Turbopuffer API key | Environment variable: `TURBOPUFFER_API_KEY` |
| `region` | Turbopuffer region | `gcp-us-central1` |
| `distance_metric` | Distance metric for vector similarity (`cosine_distance` or `euclidean_squared`) | `cosine_distance` |
| `batch_size` | Batch size for bulk operations | `100` |
| `extra_params` | Additional parameters for the Turbopuffer client | `None` |

### Regions
