- Free tier to test
- Index narrower than Google-scale crawlers

Vectara
Fully managed end-to-end RAG (ingest, retrieve, generate) behind one API, plus first-party retrieval and generation models, not a DIY stack.

- First-party multilingual retrieval models
- Open-sources HHEM and eval tooling (Apache-2.0)
