Model comparison
Compare Gemini Embedding 2 and Voyage Context 4 using the same provider-sourced embeddings & vector search rubric. No mystery score and no invented benchmark ranking.
Facts checked September 4, 2026
Set your usage. Your estimate updates as you type.
Assumes 600 tokens per page, processed separately. Actual token counts vary. This covers embedding only, not storage, search, or generated answers.
Estimates exclude taxes, tools, cache storage/writes, free allowances and custom discounts. Image estimates cover output only, not prompt or reference-image charges. Quality modes differ by model. Unlisted settings are not treated as free.

Quick take
Google's multimodal embedding model for placing text, images, video, audio, and PDFs in one searchable vector space.
Media inputs have separate limits and prices, so text-only cost estimates do not describe a multimodal index. Free-tier and paid Gemini API data-use terms also differ.
Voyage AI's document-aware embedding model that automatically creates vectors for chunks while preserving information from the surrounding document.
Automatic chunking is convenient but less application-controlled than a custom parser. Test headings, tables, citations, metadata, and update behavior before adopting it across a document estate.
Compare the published facts
Values use each provider's own published units and limits. A blank means the provider did not publish a directly comparable value in the sources reviewed.
| Embeddings & vector search | Gemini Embedding 2 | Voyage Context 4 |
|---|---|---|
| Embedding priceCurrent provider price per million input tokens or the closest published billing unit. | Text $0.20 / 1M tokens; multimodal rates vary | $0.12 / 1M tokens after 200M free |
| Input capacityMaximum content accepted in one embedding input, using the provider's documented token basis. | 8,192 text tokens; media has separate limits | 32K per internal pass; longer documents split automatically |
| Vector dimensionsSupported output sizes; smaller vectors reduce storage while larger vectors may preserve more information. | 128–3,072; 768, 1,536, or 3,072 recommended | 256, 512, 1,024, or 2,048 |
| Accepted inputsText, code, image, audio, video, PDF, or document-aware input supported by the endpoint. | Text, image, video, audio, PDF | Whole text documents |
| Retrieval controlsQuery/document modes, task types, truncation, chunking, or other controls that shape vectors for retrieval. | Task types, output dimension, title for retrieval documents | Automatic contextual chunking, overlap, and long-document splitting |
| Where it runsDirect API, cloud marketplace, private deployment, or self-hosted route documented by the provider. | Gemini Developer API and Google AI Studio | Voyage hosted API and MongoDB-integrated routes |
How to choose
Start with the job you need to complete, then validate cost, access, and policy details on your exact provider route.
Google's Gemini API terms distinguish unpaid and paid services: content from unpaid services may be used to improve products, while paid-service prompts and responses are not used to improve products.
Provider and API links
Voyage's public terms allow customer content to improve services unless the customer opts out. Eligible paid organizations can configure an opt-out and zero-day retention; separately negotiated enterprise terms may differ.

Consider Gemini Embedding 2 when your priority is Multimodal search across text and media. Consider Voyage Context 4 when your priority is Long-document RAG. Test both with your own data and provider route before committing.
No. This comparison aligns provider-published facts for the Embeddings & vector search category. It does not claim a universal winner or combine incompatible third-party benchmark scores.
