Cohere embed-v4 vs Voyage-3
A head-to-head comparison of two leading embedding models for AI-powered growth. See how they stack up on pricing, performance, and capabilities.
Cohere embed-v4
Pricing: Free trial, then $0.10 per 1M tokens
Best for: Multilingual applications and cross-language search
Voyage-3
Pricing: Free tier, then $0.06 per 1M tokens
Best for: Code search, technical documentation, and developer tools
Head-to-Head Comparison
| Criteria | Cohere embed-v4 | Voyage-3 |
|---|---|---|
| Accuracy (MTEB) | Top multilingual retrieval benchmark scores | Strong overall; best on code and technical content |
| Cost per 1M Tokens | $0.10 per 1M tokens | $0.06 per 1M tokens |
| Multilingual Support | 100+ languages, cross-lingual leader | Primarily English and code |
| Self-Hosting | Not available | Not available |
| Dimension Flexibility | Fixed 1024 dimensions | Fixed 1024 dimensions |
The Verdict
Cohere embed-v4 and Voyage-3 are both strong API-only embedding services, but they specialize in different domains. Cohere dominates for multilingual and cross-language retrieval scenarios — building a search product that spans multiple languages should strongly consider Cohere. Voyage-3 at $0.06/1M tokens is 40% cheaper than Cohere and outperforms on technical content like code, API documentation, and developer knowledge bases. Use Cohere for language-diverse applications; use Voyage-3 for technical and developer-facing products.
