Amazon Nova on Bedrock
Amazon's own foundation model family (Nova Micro, Lite, Pro, Premier) available on AWS Bedrock, offering multimodal input support, video understanding in Nova Pro, batch API, knowledge base integration, and competitive pricing compared to third-party models on Bedrock.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
IAM-based auth with fine-grained model-level permissions is one of the strongest auth models among LLM providers; supports VPC endpoints for private network access.
⚡ Reliability
Best When
You are building agents on AWS infrastructure and want Amazon's own models with native Bedrock integrations (Knowledge Bases, Guardrails, Batch API) at competitive pricing.
Avoid When
You need multi-cloud portability, model fine-tuning, or maximum reasoning capability regardless of cost.
Use Cases
- • Run cost-sensitive agent workloads using Nova Micro for text-only tasks at among the lowest per-token prices on Bedrock
- • Process video content in agent pipelines using Nova Pro's native video understanding to extract structured information from recordings
- • Use Bedrock Knowledge Bases with Nova to build RAG agents that retrieve from S3-backed document stores without managing retrieval infrastructure
- • Submit large batch inference jobs via the Bedrock Batch API to process thousands of agent queries overnight at reduced cost
- • Build multi-modal agents that handle text, image, and document inputs with Nova Lite's balanced capability and price profile
Not For
- • Teams that need to run models outside of AWS infrastructure — Nova models are exclusively available on AWS Bedrock
- • Workloads requiring the highest-capability frontier models for complex reasoning — Nova Premier is competitive but may trail GPT-4o or Claude Opus on hard benchmarks
- • Applications that need fine-tuning of foundation models — Nova fine-tuning availability is limited compared to other Bedrock models
Interface
Authentication
Authentication via AWS IAM roles and policies; supports fine-grained IAM permissions per model ARN and Bedrock action.
Pricing
Pricing varies by region; Batch API provides significant discounts for non-real-time workloads. Cross-region inference may have different rates.
Agent Metadata
Known Gotchas
- ⚠ Nova models require model access to be explicitly enabled per AWS account in the Bedrock console — agents will receive AccessDeniedException with no indication that enablement is needed
- ⚠ Cross-region inference routing can introduce latency spikes and may fail if the target region is at capacity with no automatic fallback
- ⚠ Nova Pro video understanding requires video files in S3 — agents cannot pass video via inline bytes as they can with images
- ⚠ Converse API tool use with Nova may behave differently from Claude on Bedrock regarding tool call formatting — do not assume tool schemas are drop-in compatible
- ⚠ Batch API output is written to an S3 bucket you provide — agents must poll job status and then read from S3 rather than receiving results directly in the API response
