No GA label for vector search itself is quoted; Automated Embedding is labelled Preview (see builtInEmbedding).
- Renamed
MongoDB Atlas Vector Search is now called MongoDB Vector Search
MongoDB's docs call the feature MongoDB Vector Search, and the old atlas-vector-search overview URL redirects to the new docs path. No date is stated.
“You can also use MongoDB Vector Search with self-managed or local Atlas deployments that you create with the Atlas CLI.”

How MongoDB Vector Search charges
Every price MongoDB Vector Search states, in its own unit, with the quote and where it comes from. Nothing is converted.
| Price | Unit, as stated | Quote and source | Where it comes from |
|---|---|---|---|
| Per cluster-hour (whole cluster, not vector-specific) | |||
| $0 | per hour (Atlas Free cluster) | “Free $0 /hour Free forever For learning and exploring MongoDB in a cloud environment. STORAGE 512 MB” |
|
| $0.011 | per hour, up to $30/month (Atlas Flex cluster) | “Flex $0.011 /hour Up to $30/month” |
|
| $0.08 | per hour, starts at $56.94/month (Atlas Dedicated cluster) | “Dedicated $0.08 /hour Starts at $56.94/month” |
|
Vector search runs on Atlas clusters, so these are cluster prices, not vector-specific rates.

Search and indexing
- Max dimensions
8,192
“You must specify a value less than or equal to 8192.”
mongodb.com - Distance metrics
euclidean, cosine, dotProduct
“euclidean - measures the distance between ends of vectors.”
mongodb.com “cosine - measures similarity based on the angle between vectors.”
mongodb.com “dotProduct - measures similarity like cosine, but takes into account the magnitude of the vector.”
mongodb.com - Index types
hnsw, flat
“hnsw - for graph-based index where similar vectors are connected”
mongodb.com “flat - for flat, non-graph, index”
mongodb.com - Hybrid and sparse search
Yes: $rankFusion and $scoreFusion
“You can use $rankFusion and $scoreFusion to perform a hybrid search.”

Research notes
The docs now call the feature "MongoDB Vector Search"; the old atlas-vector-search overview URL redirects to mongodb.com/docs/vector-search/. ANN search requires Atlas clusters on MongoDB v6.0.11, v7.0.2 or later per the overview. On the vector-search-type page the dimension limit, similarity and indexing-method text sits inside tabbed sections.
