Claude Opus 4.8 and Sonnet 5 Land in AWS GovCloud with New Monitoring Powers
Kiro just dropped Claude Opus 4.8 and Sonnet 5 in AWS GovCloud (US), and they're absolute beasts for heavy lifting. Opus 4.8 flexes stronger self-verification and tool calling with a 1M context window—perfect for those gnarly multi-step tasks that used to need babysitting. Sonnet 5 brings agentic coding chops at Sonnet pricing, hitting Opus-level reasoning benchmarks without breaking the bank. Plus, enterprise admins now get full visibility with built-in usage dashboards, per-user activity reports, and optional prompt logging—all stored safely in your own AWS account.
