Definition
Choice accepts a maximum of 255 options; Score accepts at least two and at most ten levels; the context window is 64k tokens for state plus all questions, with 32k for state plus the single longest question. Choice and Score answers carry confidence, while Noul returns only the probability.
The limits shape common patterns: very large candidate sets get pre-filtered or searched in two passes, and Score levels are kept few and well separated because they are weak at numeric calibration.
