Amazon Nova Lite notes
Amazon Nova Lite supports image and video inputs. Very cost-effective for multimodal pipelines. Strong choice for large-scale document processing on AWS.
o3 (Azure) notes
o3 reasoning model via Azure OpenAI Service. Best for complex analytical tasks requiring deep reasoning. Azure deployment adds enterprise security and compliance.
Frequently Asked Questions
Is Amazon Nova Lite cheaper than o3 (Azure)?
At standard usage (1,000 input tokens, 500 output tokens, 100,000 requests/month), Amazon Nova Lite costs $18.00/month versus $600.00/month for o3 (Azure) — a 97% 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 o3 (Azure)?
Amazon Nova Lite has a larger context window at 300,000 tokens, compared to 200,000 tokens for o3 (Azure). A larger context window is important for processing long documents, multi-turn conversations, or large codebases without truncation.
Do Amazon Nova Lite and o3 (Azure) support the Batch API?
Amazon Nova Lite supports the Batch API (50% discount for async processing), while o3 (Azure) does not. If your workload tolerates up to 24-hour latency, routing to Amazon Nova Lite with batch pricing could significantly cut costs versus o3 (Azure)'s standard rate.
Which model offers better prompt caching?
Neither Amazon Nova Lite nor o3 (Azure) currently supports prompt caching. For prompt-caching capable alternatives, consider Claude models from Anthropic or GPT-4o from OpenAI.
What are the best use cases for Amazon Nova Lite vs o3 (Azure)?
Both models are well-suited for Summarization, Data extraction. Amazon Nova Lite is particularly strong for Translation. o3 (Azure) 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 o3 (Azure)?
At 1,000 input tokens and 500 output tokens per request — a typical conversational workload — Amazon Nova Lite costs $0.000180 per request and o3 (Azure) costs $0.006000 per request. At 100,000 requests/month, that translates to $18.00 and $600.00 respectively. Use the interactive calculator to adjust these parameters for your actual workload.
Amazon Nova Lite vs o3 (Azure): Summary
When comparing Amazon Nova Lite and o3 (Azure) 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 $600.00/month for o3 (Azure).
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. o3 (Azure) charges $2.00/M input and $8.00/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.
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 o3 (Azure). A larger context window is essential for document summarization, large codebase analysis, and multi-document retrieval-augmented generation (RAG) applications.
Use the interactive calculator at the top of this page to enter your actual token usage and monthly request volume for a precise cost comparison tailored to your workload. Adjust for batch API discounts and prompt caching to find the most cost-effective option for your specific deployment.
