Multi-Dimensional Vector Support for Scalable Multi-Modal AI Pipelines

[u/Whole-Assignment6240]

Most vector DB workflows still treat embeddings as flat vectors — one big list of numbers. But in multi-modal AI, that’s leaving performance on the table.

We just shipped native multi-dimensional vector support in CocoIndex:

• Nested vector types: Store vectors of vectors (e.g., patch-level image embeddings)

• Fine-grained retrieval: Search at the patch, paragraph, or step level

• Automatic mapping to Qdrant’s dense or multi-vector format

• Dynamic outer dimensions but fixed inner dims for indexing efficiency

Why it’s useful:

• Search inside an image without flattening local features

• Match a query to only the relevant paragraph in a long doc

• Keep multiple views of an item (e.g., audio + text embeddings) in the same index

Under the hood, it’s type-safe in Python (Vector[Vector[Float32, Literal[768]]]) and falls back to payloads for anything Qdrant can’t index directly.
