About Voyage Finance 2
Voyage Finance 2 is Voyage AI's finance-specialized embedding model, released March 1, 2024. It features a context window of 0 tokens and targets retrieval across financial documents including corporate event summaries, public company filings, 10-K reports, tabular financial data, personal finance content, and documents requiring numerical reasoning.
Across 11 financial retrieval datasets, Voyage Finance 2 achieves an average NDCG@10 of 0.831, outperforming OpenAI text-embedding-3-large by 7% and Cohere Embed v3 English by 12%. It shows particular strength on TAT-QA (0.788), ConvFinQA (0.820), and FinQA (0.795), which test retrieval over hybrid tabular and textual financial data requiring numerical understanding.
Voyage AI built Voyage Finance 2 for expertise-intensive domains where general-purpose embedding models underperform due to specialized terminology, document structures, and reasoning patterns unique to finance. The context window of 0 tokens handles lengthy financial filings and reports without truncation. That matters for 10-K documents and multi-page research reports where key information appears deep in the text.
What To Consider When Choosing a Provider
- Configuration: Voyage Finance 2 provides the largest accuracy gains on financial documents with hybrid tabular and textual content requiring numerical reasoning. If your financial data is primarily plain text without tables or numerical queries, a general-purpose model may perform comparably.
- Configuration: The context window of 0 tokens handles lengthy 10-K filings, research reports, and multi-page financial documents without truncation. This matters most for financial retrieval where key disclosures often appear late in long documents.
- Configuration: Voyage AI's voyage-3-large now outperforms domain-specific models on financial tasks. For new deployments with mixed financial and non-financial content, evaluate voyage-3-large or voyage-3.5 as simpler alternatives.
- Zero Data Retention: AI Gateway does not currently support Zero Data Retention for this model. See the documentation for models that support ZDR.
- Authentication: AI Gateway authenticates requests using an API key or OIDC token. You do not need to manage provider credentials directly.
When to Use Voyage Finance 2
Best For
- Financial document search: 10-K filings, earnings reports, and SEC submissions where domain-specific terminology matters
- RAG pipelines for financial analysis: Retrieval of relevant tables, figures, and text from company filings
- Hybrid tabular-textual retrieval: Queries involve numerical reasoning over financial data alongside narrative content
- Compliance and regulatory workflows: Search across financial regulations, guidance documents, and enforcement actions
- Investment research: Pipelines that retrieve and rank relevant financial information from large document corpora
Consider Alternatives When
- Your content spans multiple domains beyond finance: Voyage-3.5 or voyage-3-large provides cross-domain retrieval that includes finance
- You want Matryoshka dimensionality and quantization: Voyage-3.5 offers these features while covering finance
- Your financial data is primarily plain text without tables or numerical queries: A general-purpose model may perform comparably
- You need code retrieval alongside financial data: Consider pairing with voyage-code-3 or using a general-purpose model
Conclusion
Voyage Finance 2 delivers measurable accuracy gains for financial document retrieval, particularly on hybrid tabular-textual datasets requiring numerical reasoning. Its context window of 0 tokens handles the lengthy documents common in finance without truncation. For pure financial retrieval workloads, it remains a specialized option. Access it through AI Gateway for unified provider management and usage tracking.
