Embeddings that just rank better

Voyage AI builds domain-tuned embedding and reranking models that consistently top retrieval benchmarks — legal, code, finance, and multilingual. Acquired by MongoDB in 2024, it's the default upgrade teams make when generic embeddings aren't cutting it for RAG.

Who it's for: Developers who need top-tier retrieval quality for RAG and search.

Key features

🏆 SOTA embeddings

Domain-tuned for code, law, finance.

🔁 Rerankers

Big precision gains on top of vectors.

🌐 Multilingual

Strong across languages.

🔌 Simple API

Drop-in for any pipeline.

The honest take

✓ What works

Best-in-class retrieval
Domain-specific models
Easy to swap in
Backed by MongoDB

✗ What doesn't

Paid beyond free tier
Narrower than a full platform
Less known than giants
Best value at scale

Verdict

If retrieval quality is your bottleneck, Voyage's embeddings + reranker is the highest-leverage upgrade you can make. Pair with Qdrant or Pinecone.
