What each one is
Vespa
Vespa is a production engine combining vector search, lexical search and ML-model ranking over billions of documents with real-time writes — the platform behind major web-scale services.
- True hybrid: vectors + text + ML ranking in one query
- Real-time indexing at very large scale
- Proven in production for decades at Yahoo/Verizon Media
Marqo
Marqo handles embedding generation and vector search together, so you send text or images and it does the rest — no separate embedding step.
- Embeddings generated for you
- Text and image search out of the box
- No separate embedding pipeline
