Pricing
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.
FreemiumWeaviate Cloud offers a permanently free tier: $0/month, 1 cluster per user, 100,000 objects, 1 GB memory, 10 GB disk, 1 collection with up to 3 tenants, 2,000 embeddings requests/day, and 1,000 Query Agent requests/month, no credit card required. Flex starts at $45/month on a pay-as-you-go basis with no commitment, unlimited objects, up to 1,000 collections, full core database toolkit with replication, RBAC, 99.5% uptime, and next-business-day Severity 1 support; billed on vector dimensions (from $0.00465/1M), storage (from $0.12/GiB), and backups (from $0.0264/GiB) on top of the base minimum. Premium starts at $400/month on a prepaid contract, offering choice of shared or dedicated deployment, up to 99.95% uptime, SSO/SAML, global coverage on AWS/GCP/Azure, and enterprise support as fast as 1-hour Severity 1 response with a dedicated Technical Account Team; dedicated deployment adds HIPAA compliance, AWS PrivateLink, and customer-managed encryption keys. Weaviate Embeddings is billed separately per model, from $0.025 to $0.065 per 1M tokens. Query Agent is free to try (1,000 requests/month) or $30/month per organization for 4,000 included requests plus usage-based overage.

Amazon Bedrock

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
Weaviate

Weaviate Pros & Cons

Pros

  • Genuinely free tier with no credit card required, plus fully open-source self-hosting as an alternative
  • Unifies vector search, RAG, embeddings, and personalization (Engram) in one platform instead of stitching together separate tools
  • Query Agent removes the need to hand-write vector or hybrid search syntax for common requests
  • Efficient multi-tenancy lets a single cluster support tens of thousands of isolated tenants, ideal for SaaS builders
  • Strong enterprise trust signals: SOC 2 Type II audited, HIPAA compliant on Enterprise Cloud, 20M+ open-source downloads

Cons

  • Free tier is capped at 100,000 objects and a single collection, pushing real projects to paid plans quickly
  • Premium tier requires a prepaid contract starting at $400/month, a jump from the pay-as-you-go Flex tier
  • Pricing based on vector dimensions and storage can be harder to estimate upfront than flat per-seat pricing
  • SSO/SAML, HIPAA compliance, and PrivateLink are reserved for Premium and Dedicated tiers, unavailable on Free or Flex
