Pricing
FreemiumMongoDB Atlas Vector Search is not a separately priced product; it runs on your existing Atlas cluster resources. The Free tier (M0) offers 512MB of storage and supports basic vector search for learning and prototyping at no cost. The Flex tier costs between $8 and $30/month (usage-capped, pay-as-you-go hourly), suitable for low-to-moderate production workloads and replacing the deprecated Shared and Serverless tiers as of February 2025. Dedicated clusters start at $57/month for entry-level production workloads, with hourly rates that vary by cloud provider (AWS, Azure, GCP) and region. For production workloads needing isolated vector search performance, dedicated Search Nodes (requiring a minimum of two nodes on an M10+ cluster) are billed separately, ranging from roughly $0.12/hour for an S20 node up to $4.22/hour for the largest S80 tier. Data transfer/egress is billed separately at standard per-GB cloud provider rates, and self-managed Enterprise Advanced deployments require a custom sales quote. Serverless instances were fully retired on January 22, 2026, with existing customers migrated to Free, Flex, or Dedicated tiers.
PaidAmazon Bedrock uses consumption-based pricing with no upfront commitment for on-demand use. Foundation model inference is billed per 1M input/output tokens, with rates varying by provider and model — from lightweight models like Amazon Nova Micro or Meta Llama 3 8B at a fraction of a cent per 1,000 tokens, to frontier models like Claude and GPT-5.6 ranging from $0.22 to $13.75 per 1M input tokens and $1.32 to $82.50 per 1M output tokens depending on context window.
Batch inference offers roughly 50% savings over on-demand pricing for select models, and a Flex tier offers similar discounts with relaxed latency requirements, while a Priority tier costs about 75% more for guaranteed low latency. Provisioned Throughput pricing (hourly, with 1- or 6-month commitment discounts) suits teams needing dedicated, guaranteed capacity rather than variable on-demand access.
Additional Bedrock features are billed separately: Guardrails charge per 1,000 text units (~$0.07–$0.17), Knowledge Bases charge for index storage ($5/GB/month) plus per-1,000-query retrieval fees, Model Evaluation charges standard token rates plus $0.21 per human evaluation task, and Custom Model Import is billed per unit-minute plus storage. AWS offers up to $200 in free credits for new customers.

MongoDB Atlas Vector Search Pros & Cons
Pros
- Unified data model eliminates the sync overhead of running a separate standalone vector database
- Search Nodes let you scale vector search compute independently from your core transactional workload
- Automated Embedding (powered by Voyage AI) generates and syncs embeddings with zero ML pipeline setup
- Free M0 tier makes it genuinely possible to prototype RAG and semantic search at zero cost
- Backed by a mature, public company (Nasdaq: MDB) with 125+ global regions and enterprise-grade security
Cons
- Dedicated Search Nodes require an M10+ cluster minimum, adding cost before you get isolated vector search compute
- Vector embeddings must stay under a 4096-dimension limit, which can constrain some newer, higher-dimensional embedding models
- Usage-based pricing across compute, storage, Search Nodes, and data transfer makes total cost harder to predict than a flat-rate competitor
- Best value requires already using or being willing to adopt MongoDB as your primary operational database, not just a vector store
- Serverless instances were retired in January 2026, forcing migrated customers to re-evaluate Free, Flex, or Dedicated tiers
Amazon Bedrock Pros & Cons
Pros
- Access to models from nearly every major AI lab through one consistent API and billing relationship
- No infrastructure to provision or manage, with automatic scaling built into the serverless architecture
- Strong compliance posture out of the box, useful for regulated industries like finance and healthcare
- Pay-per-use pricing means no cost for idle capacity on on-demand inference
- AgentCore and Knowledge Bases reduce the engineering lift of building production RAG and agent systems
- Deep integration with the broader AWS ecosystem for teams already building on AWS
Cons
- Usage-based pricing across dozens of models and add-on features makes cost estimation genuinely complex
- Best suited to teams already inside the AWS ecosystem; using it standalone adds a real AWS learning curve
- Some frontier models arrive on Bedrock later than on their original provider's own API
- Provisioned Throughput commitments can be expensive relative to smaller-scale on-demand usage
- Guardrails, Knowledge Bases, and Evaluation are billed as separate line items, which can obscure total spend
