Frequently Asked Questions
Is Amazon Nova Lite cheaper than o4-mini?
At standard usage (1,000 input tokens, 500 output tokens, 100,000 requests/month), Amazon Nova Lite costs $18.00/month versus $330.00/month for o4-mini — a 95% 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 Lite or o4-mini?
Amazon Nova Lite has a larger context window at 300,000 tokens, compared to 200,000 tokens for o4-mini. A larger context window is important for processing long documents, multi-turn conversations, or large codebases without truncation.
Do Amazon Nova Lite and o4-mini support the Batch API?
Yes — both Amazon Nova Lite and o4-mini 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?
o4-mini supports prompt caching at $0.28/M for cached input, while Amazon Nova Lite does not offer prompt caching. For RAG applications or chatbots with large, repeated context, o4-mini's caching capability can substantially reduce effective costs.
What are the best use cases for Amazon Nova Lite vs o4-mini?
Both models are well-suited for Data extraction. Amazon Nova Lite is particularly strong for Summarization, Translation. o4-mini is favored for Code generation. 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 Lite vs o4-mini?
At 1,000 input tokens and 500 output tokens per request — a typical conversational workload — Amazon Nova Lite costs $0.000180 per request and o4-mini costs $0.003300 per request. At 100,000 requests/month, that translates to $18.00 and $330.00 respectively. Use the interactive calculator to adjust these parameters for your actual workload.
Amazon Nova Lite vs o4-mini: Summary
When comparing Amazon Nova Lite and o4-mini for API cost, the right choice depends on your workload's token profile, required features, and tolerance for latency. Amazon Nova Lite offers lower total cost at standard usage volumes (1,000 input + 500 output tokens per request at 100,000 requests/month) at $18.00/month, compared to $330.00/month for o4-mini.
Both models are priced in USD per million tokens, the standard unit across all major AI API providers. Amazon Nova Lite charges $0.06/M for input tokens and $0.24/M for output tokens. o4-mini charges $1.10/M input and $4.40/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 o4-mini but not Amazon Nova Lite. 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: Amazon Nova Lite supports up to 300,000 tokens in a single request, versus 200,000 tokens for o4-mini. A larger context window is essential for document summarization, large codebase analysis, and multi-document retrieval-augmented generation (RAG) applications.
