Limits
- Vector Search itself works on the Free cluster; its meaningful limits are 512 MB, 100 operations/second, and three search/vector indexes.
- Automated Embedding is billed separately by token; each organisation receives one-time 200M free tokens per model that do not renew.
- MongoDB says text sent to the service is used only to generate embeddings, is not stored, and is not used for model training.
- Embeddings are stored in the customer's own database.
- MongoDB hosts the models in a US Google Cloud region; cluster, egress, and optional Search Node costs remain separate.
How we compare
