I have a question, is it possible to make an API that takes 2 vectors from the database, and it returns a position of vector B in a table of similarity of vector A against other vectors in the database?

Deda•5/20/25, 8:54 PM

I hope the question is not confusing -.-

Deda•5/20/25, 8:56 PM

example response: Vector B is in position of 52 (meaning 52 vectors are more similar than vector B to the vector A)

Hi all! Quick question just about to evaluate Vectorize. Does Vectorise need a CF Worker to work? Or can I use it to connect from other clients? Thanks!

Not really, at least not in a clean way. You could query vector a with topK = 100 (maximum possible when not using metadata) and loop it until you find the id of vector b in there. Index 0 will be Vector A (as it's 100% equal to the one you queried), and index 99 will be the one with the least similarity. But, as said, that's not clean and only works if there are max. 98 more similar vectors then vector B

Hi, why can't we use BGE-M3 embedding model (@cf/baai/bge-m3) to create vector index?

Only these model are available to choose from: [ "@cf/baai/bge-small-en-v1.5", "@cf/baai/bge-base-en-v1.5", "@cf/baai/bge-large-en-v1.5", "openai/text-embedding-ada-002", "cohere/embed-multilingual-v2.0" ]

Has anyone seen this Vectorize error?

VECTOR_QUERY_ERROR (code = 40006): invalid query vector, expected 1024 dimensions, and got 0 dimensions

My index is definitely set to 1024 dimensions, and I’m querying with a plain JS array of length 1024. Even a hardcoded array fails. Storage is under 600 vectors. Is this a known issue or am I missing something obvious?

Steak•5/25/25, 10:30 PM

I adjusted the query method call, and it worked.

Is there a way to use CF's AI to extract image embeddings?

Hey CF Team, is something off with vectorize indexing latencies? I am continously getting vectors not found via getByIds. Can anyone update the status?

please read https://developers.cloudflare.com/vectorize/best-practices/insert-vectors/ Usually people struggle with inserting vectors before reading this page

Cloudflare Docs

Insert vectors

Vectorize indexes allow you to insert vectors at any point: Vectorize will optimize the index behind the scenes to ensure that vector search remains efficient, even as new vectors are added or existing vectors updated.

I have reviewed these and the Python SDK I am using is your official SDK. I think apart from the possibility of the ndjson format being incorrect, everything else cannot be wrong. But I didn't see a detailed introduction to the ndjson format on the official website, I only saw that each line contains one json data. I tested it but it's not possible.

He's still like this, it's too difficult.

yinxingmaiming6409OP•6/9/25, 2:58 PM

I also use the official SDK, and for the simplest data, I don't think there should be any errors unless there is a problem with the official SDK?

Can I use Vectorize using only the HTTP protocol? What is the speed limit for this access.
