Agentic Search Models with OpenSearch and Elasticsearch (bonsai.io) AI

Bonsai’s Max Irwin explains how “SID-1,” a purpose-built agentic LLM for search and reranking, can improve relevance when used with OpenSearch/Elasticsearch by running multi-turn query rewriting and then a final reranking step; he describes the approach, key execution flow (tools like search, text_search, read, report_helpful_ids), and implementation details with batching (_msearch), along with reported benchmarks on speed and likelihood of surfacing relevant results.
