## When to prefer this

Choose this endpoint when you have a concrete list of factual statements and need to rapidly generate a true-or-false self-study quiz without building quiz logic yourself. It is ideal for learners, educators, or onboarding workflows where quick knowledge-check quizzes are needed from existing notes or bullet points. Prefer this over generic text generation endpoints when the explicit true-or-false quiz format and self-study orientation are required.

## Known failure modes

- Non-factual or ambiguous statements may produce poorly formed questions
