Meta released a new paper from their lab. SuperIntelligent Retrieval Agent (SIRA) achieves exceptional results across ten BEIR benchmarks.

> SIRA achieves the highest average Recall@10 and NDCG@10 in our comparison, outperforming BM25, E5, SPLADE, and recent LLM-based search agents while using no relevance labels, no retriever fine-tuning, and no embedding index. Its gains are broad, with the best Recall@10 on eight of ten datasets and especially large improvements on tasks where query and document vocabularies diverge.
