2667 questions of the kind that actually get asked — in interviews, in architecture review boards, and by the person who has to run the thing at 3 AM. Every answer states the trade-off rather than the slogan, and says when the obvious choice is the wrong one.

  2. Agent Architectures advanced

    A team is building an agent that plans and executes multi-step tasks. What architectural bounds must exist, and what usually goes wrong?

  3. Agent Architectures advanced

    An agent that researches and summarises occasionally runs for 40 minutes and costs £30 for one request. How do you contain it?

  4. 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

    A travel platform's AI feature costs vary enormously between interactions and the total is growing faster than usage. Which levers apply, in what order?

  6. AI Cost Management advanced

    An AI feature launched two months ago now costs more per month than the rest of the platform. What do you investigate?

  7. AI Cost Management advanced

    An AI feature was modelled at £0.02 per interaction. Production shows £0.11. Where did the difference come from?

  8. 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.

  9. 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?

    An LLM feature that worked last week now gives worse answers. Nothing was deployed. How do you find out what changed, and what should have been in place?

  12. AI-Era Architecture advanced

    An inference platform receives computationally expensive requests in unpredictable bursts. Should it use admission control, request queues, dynamic batching, autoscaling, priority classes or pre-provisioned capacity?
