Field notes

SeaCat accepts a state plus a structured question set, then returns bounded answers rather than generated explanations. Its example classifies a logistics-company sales message as ready, a strong target fit, and asking for pricing, while preserving probabilities for alternative answers. The response also exposes certainty and expected position for scale questions. The homepage lists a 32,768-token context limit, up to 64 questions per request, and pricing based on input tokens.
