Legacy model. Voyage lists the voyage-3 family as older models with no free-token allowance. Newer option: voyage-4-lite at $0.02 per 1M tokens.
What does it cost to embed a corpus with Voyage 3 Lite?
Embedding cost is a one-time charge per document — unlike LLM inference, you only pay to embed each chunk once at ingest time. Re-embedding only happens when you re-chunk or swap models.
| Corpus size | Tokens | One-time embed cost |
|---|---|---|
| Small docs corpus (~1M tokens) | 1,000,000 | $0.0200 |
| Mid-size corpus (~50M tokens) | 50,000,000 | $1.0000 |
| Enterprise corpus (~500M tokens) | 500,000,000 | $10.0000 |

Vector database sizing — what 512-dim vectors cost to store
Each Voyage 3 Lite embedding is a 512-dimensional float32 vector, ~ 2.00 KB per vector. At 1M vectors that's ~ 1953.1 MB of raw vector data (before index overhead). Compare against alternates with different dimension counts:
- OpenAI text-embedding-3-small: 1536 dims → 5859.4 MB per 1M vectors
- OpenAI text-embedding-3-large: 3072 dims → 11718.8 MB per 1M vectors
- Voyage 3 Large: 2048 dims → 7812.5 MB per 1M vectors
- Voyage 3 Lite: 512 dims → 1953.1 MB per 1M vectors
- Cohere Embed v4: 1024 dims → 3906.3 MB per 1M vectors
- Gemini Embedding: 768 dims → 2929.7 MB per 1M vectors
