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.
Customwatsonx pricing varies by product and is largely consumption-based. watsonx.ai offers a free trial with up to 300,000 tokens per month, then a Standard plan starting around $1,050-$1,110/month including a block of capacity unit hours (CUH), with additional usage billed pay-as-you-go; foundation model inference is billed per million tokens, ranging from roughly $0.10/million tokens for select IBM and third-party models up to $20+/million tokens for larger models, with third-party models from Meta, Google, DeepSeek, and Mistral also available on a pay-as-you-go basis. watsonx.data uses tiered plans starting with a free trial and scaling to an Enterprise plan for production data lakehouse workloads, billed per Resource Unit (compute metered per second). watsonx Orchestrate offers a 30-day free trial, then an Essentials plan starting at $500/month for core agent building and orchestration, and a Standard plan (roughly $530+/month per G2 data) with custom, quote-based pricing for higher throughput and prebuilt domain agents. watsonx.governance pricing is quote-based and typically bundled with watsonx.ai and watsonx.data commitments; IBM offers discount tiers for customers committing across multiple watsonx products at $500K, $1.5M, and $5M+ in annual contract value. All products can be purchased through the IBM Cloud Catalog or AWS Marketplace, and on-premises deployment is priced separately through IBM Software licensing.

Summary
The fully managed AWS platform for building generative AI applications and agents at production scale
IBM's enterprise AI portfolio for building, governing, and deploying AI
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
IBM watsonx Pros & Cons
Pros
- Full-stack enterprise AI portfolio (build, data, govern, orchestrate) from a single vendor
- Strong AI governance credentials, named a Leader in the 2026 Gartner Magic Quadrant for AI Governance Platforms
- Model choice within a governed environment, spanning IBM Granite and third-party models from Meta, Google, DeepSeek, and Mistral
- Flexible hybrid deployment across IBM Cloud, AWS, Azure, or fully on-premises for strict compliance needs
- Deep enterprise track record with named customers like Vodafone, the US Open, and Dun & Bradstreet
Cons
- Pricing is complex and fragmented across products, mixing per-token, Capacity Unit Hour, and Resource Unit metrics that require real modeling to estimate total cost
- Entry pricing is enterprise-scale (watsonx.ai Standard starts around $1,050+/month), pricing out smaller teams and individual developers
- Full value requires committing across multiple watsonx products, since standalone deployments miss the better multi-product discount tiers
- Steeper learning curve than single-purpose AI tools, given the breadth of the portfolio
- Strongest integration and support experience sits within the IBM ecosystem, with less native depth for teams already standardized on AWS, Azure, or GCP-native AI stacks
