Các lựa chọn
Đáp án được giữ gọn theo nhãn A, B, C, D trong phần bình chọn tương tác.
- A. Add additional repeated content to the system prompt to give the model more guidance.
- B. Increase retrieval depth on every request to maximize recall, worsening the dominant cost driver by adding more retrieved tokens per request rather than reducing them.
- C. Switch every request to the heaviest available model to maximize output quality, accepting that higher per-request inference cost compounds rather than addresses the dominant cost driver.
- D. Move the long, repeated system prompt into a cacheable prefix and trim retrieved context to the spans relevant to each query. — đáp án hiện tại
Answer researched independently against supporting documentation; not a published source answer key. Independent reasoning (not a published answer key): Caching the repeated prefix and selecting only relevant passages target the stated dominant input-token costs.
