Last verified against current AWS documentation ·How we write our questions

An engineering firm wants a foundation model to answer questions about scanned site diagrams.

Each specification volume runs to hundreds of pages and must be sent in a single request.

Which TWO selection criteria matter MOST for this use case? (Choose two.)

Choose two answers.

  1. A. The model accepts image inputs as well as text, so it can read diagram scans
  2. B. The model has the largest parameter count in its model family
  3. C. Its context window is large enough to hold a full specification volume
  4. D. It was the most recent model its provider released this year
  5. E. It is the model most often discussed in technical forums online
Show the answer and explanation

Answers: A, C

  • A. Right: Correct. The diagrams are images, so the model must accept image input or the scans cannot be read directly. This is a requirement to check for each candidate model.
  • B. Wrong: Parameter count is not a fit test on its own. A larger model can cost more and respond more slowly, and it may still not accept images or long inputs.
  • C. Right: Correct. A large context window lets a full specification volume go in one request. Without one, the team must split the text and retrieve passages, which adds design work.
  • D. Wrong: Release date says nothing about whether the model reads images or handles long inputs. A newer model can still fail both requirements.
  • E. Wrong: Popularity is not a selection criterion. Capabilities, input limits, cost, latency and compliance decide whether a model fits the workload.

Explanation

Choose a foundation model by matching its capabilities to the task. The diagrams need image input, and the full specification volumes need a context window large enough to hold them. Size, release date and popularity do not decide the fit.
