Overview

Voyage AI by MongoDB serves embedding, multimodal embedding, and reranking models over an OpenAI-style REST API. Every account carries a free token allocation per model, documented on the official pricing page. Free tokens apply to standard API usage but not to the Batch API.

Free Tier Quotas & Limits

Official pricing page wording: "The first 200 million tokens for voyage-4-large, voyage-4, voyage-4-lite, voyage-context-4, and voyage-code-3, or the first 50 million tokens for voyage-multilingual-2, voyage-finance-2, voyage-law-2, and voyage-code-2, are free for every account."

200 million free tokens each: voyage-4-large, voyage-4, voyage-4-lite, voyage-context-4, voyage-code-4, rerank-3, rerank-3-lite.
50 million free tokens each: voyage-multilingual-2, voyage-finance-2, voyage-law-2, voyage-code-2.
Multimodal: voyage-multimodal-3.5 and voyage-multimodal-3 include 200M free text tokens and 150B free pixels; each video frame counts as an image.
The reranker table lists 200 million free tokens for rerank-3 and rerank-3-lite and zero for rerank-2.5 and rerank-2.5-lite.
Older models are not eligible. Batch API tokens are billed and do not deduct from the free balance.

Paid rates after the free allocation run from $0.02 per million tokens (voyage-4-lite, rerank-3-lite) to $0.12 per million tokens.
