Core Background & Industry Pain Points
Production agents usually need a self-built harness: sandboxes, sessions, tools, and recovery. On 2026-11-05 Moonshot officially launched Kimi Hosted Agents as Harness as a Service. Start at platform.kimi.com.
Architecture Highlights & Internals
Sessions persist as events; built-in tools run in isolated cloud sandboxes; the platform can resume after failures; traces are exportable. Skills, plugins, and MCP are supported. Optional Inference Hook applies enterprise rules before inference. Enterprise-verified users can bind self-hosted Workers for sandbox tools.
Authoritative Benchmarks & Measured Scores
No standalone public agent benchmark shipped with the GA note. Customer quotes in the announcement are vendor/customer-reported. Validate with your tasks and official template cost estimators (sandbox + tokens + plugins).
