1. Agent Architectures advanced

    Review this design. A finance team's invoice processor uses a planner agent that decomposes each invoice into subtasks, a critic agent that reviews the plan, a vector store of the last 50000 processed invoices as episodic memory, a 40-step tool loop, and a human queue for anything the critic flags. The task is to extract six fields and post them to the ledger. What would you remove and what would you keep?

  5. AI Cost Management advanced

    An inference platform receives a burst of expensive long-context requests that would starve short interactive ones. Design admission control, priority classes, token-based limits and batching so interactive latency SLOs hold.

  6. AI-Era Architecture advanced

    An AI platform serves computationally expensive requests with unpredictable bursts, where one request can occupy an accelerator for seconds. What is the architectural shape, and which control is most often misplaced?
