Structured decisions

Span-01 Lite is the free, lighter tier of Respan's Span-01. For each plain-language behaviour you define, it returns the probability that the behaviour appears in a span of conversation. It suits high-volume evaluation and monitoring where cost matters more than the last bit of accuracy.

Through Hormouz it is reached at POST /v1/alpha/decisions with your ordinary API key. The request carries a state and the questions, and the reply comes back typed, so your code branches on the numbers instead of parsing a sentence. It is currently free to use through Hormouz.

Hormouz provides stable access to the model from inside Iran, with no foreign credit card or circumvention tooling required.
