The reported results suggest that explicit low thinking may be a better first optimization than a router, while routing can help on short, standalone tasks when its accuracy and overhead are measured against a strong baseline.","published_at":"2026-11-04","updated_at":"2026-11-04","record_date":"2026-11-04","date_kind":"published_at","topics":["google","gemini","coding-agents"],"entities":["Google","Google Antigravity","Gemini 3.8 Flash","Gemini 3.1 Pro","TypeSafe Jev","DiffusionGemma"],"related_patterns":["agent-economics-moves-to-completed-work"],"novelty_label":"new_fact","what_changed":"Google describes a Jev classifier routing Gemini calls by task complexity, with a 50-question benchmark; the cited prior pieces discuss model routing generally but not this classifier, setup, or results.","prior_refs":["memory:4b94e8f7-0bec-8796-aea8-4d86bb18a942","memory:1bf64c18-b949-89ba-aa02-0046ebc5d1c4"],"source_url":"https://developers.googleblog.com/cost-per-task-using-cheap-classifiers-to-route-across-gemini-models-and-thinking-levels","source_urls":["https://developers.googleblog.com/cost-per-task-using-cheap-classifiers-to-route-across-gemini-models-and-thinking-levels"],"schema_version":"newruntime-agent-readable-v0.2","stable_id":"post:cost-per-task-using-cheap-classifiers-to-route-45b43e","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/cost-per-task-using-cheap-classifiers-to-route-45b43e/","markdown":"https://newruntime.com/posts/cost-per-task-using-cheap-classifiers-to-route-45b43e.md","json":"https://newruntime.com/posts/cost-per-task-using-cheap-classifiers-to-route-45b43e.json"},"next_reads":[{"type":"topic","path":"/topics/google/","url":"https://newruntime.com/topics/google/","title":"Google","reason":"Explore the google topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/google.md","json_url":"https://newruntime.com/topics/google.json"},{"type":"topic","path":"/topics/gemini/","url":"https://newruntime.com/topics/gemini/","title":"Gemini","reason":"Explore the gemini topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/gemini.md","json_url":"https://newruntime.com/topics/gemini.json"},{"type":"topic","path":"/topics/coding-agents/","url":"https://newruntime.com/topics/coding-agents/","title":"Coding Agents","reason":"Explore the coding-agents topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/coding-agents.md","json_url":"https://newruntime.com/topics/coding-agents.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":"/source-ledger.json","url":"https://newruntime.com/source-ledger.json","title":"Source Ledger","reason":"Inspect the public source evidence graph.","media_type":"application/json"}]}
