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.
