# Nova Pro

A wrong number in a filing, a missed clause in a contract, or a missed bug in a large diff can be expensive. Nova Pro is Amazon's first-generation Nova tier aimed at higher-stakes multimodal accuracy.

## About

Nova Pro launched on December 3, 2024 as the accuracy-focused tier in Amazon's first Nova generation. Its purpose is clear: deliver the highest accuracy the first-generation architecture can achieve, particularly on structured and complex inputs where cheaper models produce unreliable results.

The accuracy advantage shows most clearly in three categories.

First, structured documents. Financial reports with dense tabular data, legal contracts with nested conditional clauses, and regulatory filings where a single misinterpreted figure cascades into downstream errors. Nova Pro parses tables correctly, maintains numerical consistency across a long context, and distinguishes between semantically similar but legally distinct phrasings.

Second, large codebases. Nova Pro reasons over up to 15,000 lines of code in a single request. Entire modules can be evaluated in context for automated code review, migration analysis, and refactoring assessments. The model tracks variable state, identifies subtle logic errors, and assesses architectural patterns across files.

Third, combined visual and textual evidence. An insurance platform can analyze a policy document alongside claim photos. A manufacturing quality system can compare product specs against inspection images. Nova Pro accepts text, images, and video in the same request. Its accuracy advantage over Nova Lite is most pronounced when visual content contains structured information (charts, schematics, annotated diagrams) that requires precise interpretation.

## What to consider

Nova Pro is the top input rate in the first-generation Nova lineup on AI Gateway. Watch the AI Gateway cost dashboard so Pro spend matches the error cost you avoid.

## When to use

### Best For

- Financial document processing where precision on tables, figures, and numerical data is non-negotiable
- Automated code review and migration analysis for codebases up to 15,000 lines per request
- Multi-document reasoning: comparing contracts, cross-referencing reports, validating data against documentation
- Combined visual and textual analysis in regulated industries (insurance, healthcare, legal)

### Consider Alternatives When

- The task is routine classification or extraction and doesn't require Pro-level accuracy. Nova Lite handles multimodal inputs at a fraction of the cost
- You need extended thinking, agentic workflows, or web grounding. Nova 2 Lite provides those second-generation capabilities
- The workload is text-only. Nova Micro is significantly cheaper and faster for pure text processing

## Frequently asked questions

### What makes Nova Pro more accurate than Nova Lite on financial documents?

Nova Pro is tuned for precision on structured inputs, including tables with dense numerical data, nested clauses, and cross-referenced figures. Nova Lite may approximate values or miss conditional relationships in complex documents. Pro maintains consistency across the full context.

### How large of a codebase can Nova Pro analyze in one request?

Up to 15,000 lines of code per request within the context of 300K tokens. For larger codebases, split across multiple requests or focus on specific modules.

### When does the cost premium over Nova Lite pay for itself?

Whenever the cost of an incorrect output exceeds the per-token price difference. In financial compliance, legal review, and code quality assessment, a single error caught by Pro that Lite would have missed can justify hundreds of requests at the higher rate.

### Can Nova Pro handle complex reasoning tasks like multi-step proofs or planning?

Nova Pro prioritizes accuracy within its generation but doesn't include extended thinking or configurable reasoning budgets. For deliberate multi-step reasoning, use Nova 2 Lite, a second-generation model with those capabilities.

### Is Nova Pro suitable as the default model in a high-volume pipeline?

Usually not as a blanket default. Its input rate is well above Nova Lite's. Most teams route easy traffic to Lite or Micro and send only high-risk work to Pro.

### What regulated-industry workflows benefit most from Nova Pro?

Insurance claims processing that combines policy documents with photographic evidence, healthcare record analysis where numerical lab values must be parsed precisely, and legal contract comparison where subtle phrasing differences have material consequences.
