Whiteboard: Applications of foundation models

Knowing the Applications of foundation models services is one thing. Knowing where each one goes is another. Each round gives you a requirement and a diagram with empty boxes: drag the right services in, leave the decoys out, and read why each piece fits.

A taste of what you will get

  • Lawyers ask questions in plain English. Answers must quote the firm's own precedents, which change every week, and cite where each point came from.

    Sample design 1: Omar's research assistant. Which service fills the empty box?

    • Amazon Bedrock Knowledge Bases
    • Amazon Polly
    • AWS Artifact

    Answer: Amazon Bedrock Knowledge Bases. Retrieves the passages that match the question and adds them to the prompt (RAG), with citations.

  • Omar has 3,000 labelled examples of the firm's clauses (each request with its ideal clause). He wants a model that drafts in that style, and proof it beats the base model before lawyers use it.

    Sample design 2: Omar's clause drafter. Which service fills the empty box?

    • Amazon Polly
    • Continued pre-training
    • Fine-tuning on Amazon Bedrock

    Answer: Fine-tuning on Amazon Bedrock. Trains a custom version of a foundation model on labelled prompt-and-answer examples.

  • A wrong answer pays nothing. It does not cost you anything either.
