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.

  4. AI Gateways advanced

    An AI gateway now terminates streaming responses for six products and holds a semantic cache shared across tenants. Two properties of that design have caused real outages and real data exposure at large AI providers. What has the organisation taken on and when does the bill arrive?

  8. AI Observability advanced

    Anthropic reported in 2025 that a routing bug sent a share of Claude Sonnet 4 requests to servers configured for a different context length, peaking at 16% of those requests in the worst hour on 31 August, and that it took weeks to identify. Error rates never moved. Which design decision allowed the delay and what telemetry closes it?

  10. AI Observability advanced

    You are asked to log every prompt and response for an assistant handling 2 million interactions a day, so quality regressions are diagnosable. Roughly how much data does that commit you to per year, and does the number change the design?
