·2026.11.06 14:00

Key point

AI Gateway and AI Studio provide integrated management of LLM and Agent calls while controlling costs and security.

Details

  • Built a governance framework by integrating LLM and MCP calls via a LiteLLM-based AI Gateway and automating requests and approvals in AI Studio
  • Applied prompt caching to Project A, increasing the cache ratio from 5% to 97% and reducing the cost per request by 84%
  • Agents use only MCP tools that have passed channel and user permissions and security reviews, and execute data queries with the permissions of the requesting account
  • Separated AI Gateway and AI Studio into distinct AWS accounts and VPCs, and protected the platform itself through zero-downtime deployments and alternative model integration
  • Costs are aggregated in real-time by the Gateway to send budget alerts, sensitive information is processed by an in-house self-hosted model, and PII guardrails are applied
  • Plans include an Agent Registry, session cost limits, Agent-level authentication and authorization, expanded guardrails, and expanded automated approval scope
