Independent support-routing evaluation of decision models.

Decision models answer a bounded question with one typed result: a choice, a score or a probability. Three of them, OpenAI’s Decisions API and a structured-output LLM baseline routed the same held-out support messages.

Live API requires sign-in and offers up to 5 free site comparisons per day, resetting at 00:00 UTC. It sends your message to selected providers; attempts including provider errors count, and provider billing for exported code is separate. Your draft is kept in this tab through sign-in.
