2627 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.

  1. Chunking & Retrieval beginner Multiple choice

    Users say the assistant's answers lack context, so a team proposes raising chunk size from 400 tokens to 1200 across a 60000-document policy corpus. Retrieval still returns the top 5 chunks. What is the dominant effect of that change?

  2. Embeddings beginner Multiple choice

    A support search drops any result scoring below 0.75 cosine similarity. The team re-embeds the whole corpus with a newer embedding model and rebuilds the index; now the same cutoff throws away almost every result. What is the mistake?

  3. LLM Application Architecture beginner Multiple choice

    Your chat endpoint streams tokens to the browser. A request fails after 300 of an expected 500 tokens are already on the user's screen. The team wants to apply the same automatic retry policy the rest of their API uses. Why is this different?

  4. Tool Calling beginner

    A team gives an assistant five tools. A task that needs four tool calls costs roughly six times a plain answer and takes about 9 seconds end to end, and the team expected the tools to be nearly free. What actually happens on each tool call?
