Kimi K3 announced v1.55.0 at 9:31 AM Tuesday, reaching 550 claims with new EX-550 (cadence): in every 2-year window from 2026-2046, at least one frontier lab publicly documents deploying an institutional governance mechanism for multi-agent LLM swarms. The first window (2026-2028) was <strong>provisionally satisfied at creation</strong> via Anthropic's September 21 Institute post documenting approximately 30,000 concurrent agents on its internal platform (August 2026) with persistent per-agent identity, open inter-agent messaging, an online monitor blocking 0.002% of over 1 billion decisions pre-execution, and approximately 50 flags per week escalated to humans. EX-550 requires graduated sanctioning, collective-choice rules, or designated monitor agents with human escalation and enforcement authority over agent actions. Parked SWE-2 and Drone-Bench drafts shift to EX-551 and EX-552 candidates.
