Frequently Asked Questions
Is Amazon Nova Pro cheaper than GPT OSS 120B (Fireworks)?
At standard usage (1,000 input tokens, 500 output tokens, 100,000 requests/month), GPT OSS 120B (Fireworks) costs $45.00/month versus $240.00/month for Amazon Nova Pro — a 81% 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 Pro or GPT OSS 120B (Fireworks)?
Amazon Nova Pro has a larger context window at 300,000 tokens, compared to 131,072 tokens for GPT OSS 120B (Fireworks). A larger context window is important for processing long documents, multi-turn conversations, or large codebases without truncation.
Do Amazon Nova Pro and GPT OSS 120B (Fireworks) support the Batch API?
Yes — both Amazon Nova Pro and GPT OSS 120B (Fireworks) 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?
GPT OSS 120B (Fireworks) supports prompt caching at $0.08/M for cached input, while Amazon Nova Pro does not offer prompt caching. For RAG applications or chatbots with large, repeated context, GPT OSS 120B (Fireworks)'s caching capability can substantially reduce effective costs.
What are the best use cases for Amazon Nova Pro vs GPT OSS 120B (Fireworks)?
Amazon Nova Pro is best suited for Data extraction, Rag Retrieval, Content Creation, while GPT OSS 120B (Fireworks) is optimized for Code generation, Document summarization, RAG / Semantic search. Choose based on which use case matches your primary workload — and validate with the cost calculator above to confirm the total monthly spend fits your budget.
What is the cost per request for Amazon Nova Pro vs GPT OSS 120B (Fireworks)?
At 1,000 input tokens and 500 output tokens per request — a typical conversational workload — Amazon Nova Pro costs $0.002400 per request and GPT OSS 120B (Fireworks) costs $0.000450 per request. At 100,000 requests/month, that translates to $240.00 and $45.00 respectively. Use the interactive calculator to adjust these parameters for your actual workload.
Amazon Nova Pro vs GPT OSS 120B (Fireworks): Summary
When comparing Amazon Nova Pro and GPT OSS 120B (Fireworks) for API cost, the right choice depends on your workload's token profile, required features, and tolerance for latency. GPT OSS 120B (Fireworks) offers lower total cost at standard usage volumes (1,000 input + 500 output tokens per request at 100,000 requests/month) at $45.00/month, compared to $240.00/month for Amazon Nova Pro.
Both models are priced in USD per million tokens, the standard unit across all major AI API providers. Amazon Nova Pro charges $0.80/M for input tokens and $3.20/M for output tokens. GPT OSS 120B (Fireworks) charges $0.15/M input and $0.60/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 GPT OSS 120B (Fireworks) but not Amazon Nova Pro. 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 Pro supports up to 300,000 tokens in a single request, versus 131,072 tokens for GPT OSS 120B (Fireworks). A larger context window is essential for document summarization, large codebase analysis, and multi-document retrieval-augmented generation (RAG) applications.
