Frequently Asked Questions
Is Amazon Nova Micro cheaper than Claude Haiku 3.5?
At standard usage (1,000 input tokens, 500 output tokens, 100,000 requests/month), Amazon Nova Micro costs $10.50/month versus $280.00/month for Claude Haiku 3.5 — a 96% saving. Your actual savings will vary based on your token profile; output-heavy workloads amplify differences in output pricing.
Which model has a larger context window, Amazon Nova Micro or Claude Haiku 3.5?
Claude Haiku 3.5 has a larger context window at 200,000 tokens, compared to 128,000 tokens for Amazon Nova Micro. A larger context window is important for processing long documents, multi-turn conversations, or large codebases without truncation.
Do Amazon Nova Micro and Claude Haiku 3.5 support the Batch API?
Yes — both Amazon Nova Micro and Claude Haiku 3.5 support batch API processing, which offers a 50% discount on input and output costs in exchange for up to 24-hour turnaround. Ideal for offline workloads like bulk document processing or nightly classification pipelines.
Which model offers better prompt caching?
Claude Haiku 3.5 supports prompt caching at $0.08/M for cached input, while Amazon Nova Micro does not offer prompt caching. For RAG applications or chatbots with large, repeated context, Claude Haiku 3.5's caching capability can substantially reduce effective costs.
What are the best use cases for Amazon Nova Micro vs Claude Haiku 3.5?
Both models are well-suited for Text classification, Customer support, Data extraction. Amazon Nova Micro is particularly strong for overlapping tasks. Claude Haiku 3.5 is favored for similar workflows. At the same quality level, the lower-cost model is usually preferable; use this page's calculator to compare total monthly spend at your volume.
What is the cost per request for Amazon Nova Micro vs Claude Haiku 3.5?
At 1,000 input tokens and 500 output tokens per request — a typical conversational workload — Amazon Nova Micro costs $0.000105 per request and Claude Haiku 3.5 costs $0.002800 per request. At 100,000 requests/month, that translates to $10.50 and $280.00 respectively. Use the interactive calculator to adjust these parameters for your actual workload.
Amazon Nova Micro vs Claude Haiku 3.5: Summary
When comparing Amazon Nova Micro and Claude Haiku 3.5 for API cost, the right choice depends on your workload's token profile, required features, and tolerance for latency. Amazon Nova Micro offers lower total cost at standard usage volumes (1,000 input + 500 output tokens per request at 100,000 requests/month) at $10.50/month, compared to $280.00/month for Claude Haiku 3.5.
Both models are priced in USD per million tokens, the standard unit across all major AI API providers. Amazon Nova Micro charges $0.04/M for input tokens and $0.14/M for output tokens. Claude Haiku 3.5 charges $0.80/M input and $4.00/M output. If your workload is output-heavy (more tokens generated than consumed as input), the model with the lower output price compounds cost savings significantly at scale.
Prompt caching is supported by Claude Haiku 3.5 but not Amazon Nova Micro. For workloads with large, repeated system prompts or document context — such as RAG pipelines or multi-turn conversations with a fixed knowledge base — prompt caching can reduce effective input costs by 60–90%, which may change the cost ranking between these two models at your specific usage pattern.
Context window capacity differs between the two: Claude Haiku 3.5 supports up to 200,000 tokens in a single request, versus 128,000 tokens for Amazon Nova Micro. A larger context window is essential for document summarization, large codebase analysis, and multi-document retrieval-augmented generation (RAG) applications.
