OpenSearch veterans launch Infino, a retrieval layer for AI agents

Infino has launched an agent retrieval platform that replaces fragmented SQL, search and vector stacks with a single layer over Apache Parquet in object storage. The core engine is open source under Apache-2.0, with a hosted Infino Cloud service.

• Infino combines ranked search, filters, joins and aggregates in one SQL query
• Data is kept in a single Parquet copy with indexes embedded by the file footer
• The core engine is open source on GitHub under Apache-2.0
• Targeted inference models handle simple retrieval tasks cheaper than frontier models
