What are Infinity and Marqo?
Infinity
Infinity is an open-source AI-native database built for embedding, full-text and hybrid search with very low latency. It is self-hosted and serves as a high-performance search and retrieval backend.
- AI-native database
- Vector and full-text search
- Hybrid retrieval
- Self-hostable
Marqo
Marqo is an open-source, end-to-end search engine that combines vector generation, storage and retrieval. It handles embedding creation automatically so you can run semantic search over text and images.
- Built-in embedding generation
- Text and image semantic search
- No separate ML pipeline needed
- Simple REST API
