Upstash Vector is a serverless vector database with built-in embedding models.

​
Usage with Upstash embeddings

You can enable the built-in embedding models by setting enable_embeddings to True. This allows you to use Upstash’s embedding models for vectorization. 
import os
from mem0 import Memory

os.environ["UPSTASH_VECTOR_REST_URL"] = "..."
os.environ["UPSTASH_VECTOR_REST_TOKEN"] = "..."

config = {
    "vector_store": {
        "provider": "upstash_vector",
        "enable_embeddings": True,
    }
}

m = Memory.from_config(config)
m.add("Likes to play cricket on weekends", user_id="alice", metadata={"category": "hobbies"})
Setting enable_embeddings to True will bypass any external embedding provider you have configured.
