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.

  5. Chunking & Retrieval intermediate

    A live assistant serves 1.8M documents chunked at a fixed 512 tokens with no overlap. You need to move to structure-aware chunks of about 900 tokens with 15% overlap and a newer embedding model, with no downtime and no quality regression. What is the sequence?

  8. Guardrails intermediate Multiple choice

    Your output safety classifier blocks 0.3% of responses in English and 6% in Portuguese and Turkish. Complaints arrive only from those two markets. The vendor confirms the same model version serves every region and reports no incident. Where do you look first?
