On a Natural Questions benchmark with about 2.6 million passages, its KeyNet approach reached 99% recall at 0.23 ms, compared with 1.8 ms for raw-query search. The result suggests a way to trade offline training for faster retrieval on stable workloads.","published_at":"2026-11-12","updated_at":"2026-11-12","record_date":"2026-11-12","date_kind":"published_at","topics":["retrieval"],"entities":["Apple","SupportNet","KeyNet","Natural Questions","FAISS"],"related_patterns":[],"novelty_label":"new_fact","what_changed":"Apple researchers introduced a learned retrieval method that uses small neural networks to make RAG document search faster and more accurate.","prior_refs":[],"source_url":"https://machinelearning.apple.com/research/faster-retrieval","source_urls":["https://machinelearning.apple.com/research/faster-retrieval"],"schema_version":"newruntime-agent-readable-v0.2","stable_id":"post:faster-retrieval-for-better-more-efficient-rag-apple-e9345b","status":"published","visuals":[],"editor":{"role":"editor","name":"Andrey Reshetnikov","profile":"https://newruntime.com/owner-profile.md","profile_json":"https://newruntime.com/owner-profile.json","same_as":["https://www.linkedin.com/in/reshetnikov1/","https://t.me/lapetuse"]},"routes":{"html":"https://newruntime.com/posts/faster-retrieval-for-better-more-efficient-rag-apple-e9345b/","markdown":"https://newruntime.com/posts/faster-retrieval-for-better-more-efficient-rag-apple-e9345b.md","json":"https://newruntime.com/posts/faster-retrieval-for-better-more-efficient-rag-apple-e9345b.json"},"markdown_url":"https://newruntime.com/posts/faster-retrieval-for-better-more-efficient-rag-apple-e9345b.md","next_reads":[{"type":"topic","path":"/topics/retrieval/","url":"https://newruntime.com/topics/retrieval/","title":"Retrieval","reason":"Explore the retrieval topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/retrieval.md","json_url":"https://newruntime.com/topics/retrieval.json"},{"type":"collection","path":"/posts/","url":"https://newruntime.com/posts/","title":"Field Notes","reason":"Open the latest editorial analysis.","media_type":"text/html","json_url":"https://newruntime.com/posts.json"},{"type":"collection","path":"/sources/","url":"https://newruntime.com/sources/","title":"Sources","reason":"See the original sources this archive cites.","media_type":"text/html"}]}
