What it does
Voyage AI offers embedding and reranking models for search and retrieval-augmented generation (RAG): turn text, code or images into vectors for semantic search, and rerank search results by how well they match a question. There are general, multilingual, code, finance and law models. Requests are JSON POST calls with an API key. Free with a free API key for the first 200 million tokens per account on most current models; paid per token after that.
