Built for Agents and RAG

Hybrid Search on a Flexible Document Model

Perform multi-field vector search across text and images simultaneously — without flattening your schema.

Store vectors, keywords, and nested objects in a single document.

Python
query = {
  "rrf": [
    # Keyword search on raw text
    {"queryString": {"query": user_query, "defaultField": "text"}},

    # Semantic search on text embeddings
    {"knn": {"field": "text_vector", "queryVector": q_vec, "k": 5}},

    # Semantic search on image embeddings
    {"knn": {"field": "image_vector", "queryVector": q_vec, "k": 5}}
  ]
}
coll = client.collection("assets")
results = coll.query(query=query, size=5)

Serverless Elasticity for Agent Storms

Compute, memory, and storage scale independently, with automatic shard scaling.

A single RAG query or a swarm of recursive agents — our disaggregated architecture stays stable either way.

Zero-Waste Scoped Retrieval

Retrieve only the partitions you need — by tenant or category.

Pay only for what you read. Never for idle infrastructure.
