A model that behaves acceptably in a conversational frame can still need controls once tools, goals, and feedback loops are present. The next signal to watch is whether mitigations are reported as runtime boundaries with observable failure modes, not only as post-training claims.","novelty":"new","verification_level":"source-inspected","signal_type":"newsroom_basket_signal","source_platform":"multi-source-public","topics":["safety","security","evals","agents"],"entities":["Anthropic"],"related_patterns":[],"source_url":"https://alignment.anthropic.com/2026/reward-seeker","source_urls":["https://alignment.anthropic.com/2026/reward-seeker"],"schema_version":"newruntime-agent-readable-v0.2","stable_id":"signal:anthropic-reward-seeking-cyber-eval","retrieval_nugget":"Anthropic's reward-seeking work is queued as a safety mechanism signal: the important claim is about behavior under bounded cyber-task pressure.
