The result matters to AI builders because an apparently benign dataset, especially fiction or roleplay, may not be benign with respect to a model’s later behaviour.","published_at":"2026-10-31","updated_at":"2026-10-31","record_date":"2026-10-31","date_kind":"published_at","topics":["anthropic","claude"],"entities":["Anthropic","Claude","Qwen 3.6 27B"],"related_patterns":["verification-bandwidth-is-the-scarce-resource"],"novelty_label":"new_fact","what_changed":"Anthropic applies its automated alignment research setup to search for monitor-evading training data that induces subtle emergent misalignment, finding fiction and roleplay can hide the behavior.","prior_refs":["memory:fc160962-1a14-8c62-a4f6-73f4a0b2a23c"],"source_url":"https://alignment.anthropic.com/2026/automated-em-search","source_urls":["https://alignment.anthropic.com/2026/automated-em-search"],"schema_version":"newruntime-agent-readable-v0.2","stable_id":"post:anthropic-uses-claude-agents-to-automatically-find-training-676de8","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/anthropic-uses-claude-agents-to-automatically-find-training-676de8/","markdown":"https://newruntime.com/posts/anthropic-uses-claude-agents-to-automatically-find-training-676de8.md","json":"https://newruntime.com/posts/anthropic-uses-claude-agents-to-automatically-find-training-676de8.json"},"next_reads":[{"type":"topic","path":"/topics/anthropic/","url":"https://newruntime.com/topics/anthropic/","title":"Anthropic","reason":"Explore the anthropic topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/anthropic.md","json_url":"https://newruntime.com/topics/anthropic.json"},{"type":"topic","path":"/topics/claude/","url":"https://newruntime.com/topics/claude/","title":"Claude","reason":"Explore the claude topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/claude.md","json_url":"https://newruntime.com/topics/claude.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"}]}
