Model Description
Span-01 is a behavior scoring model from Respan. It reads a conversation span and returns, for each plain-language behavior you define, the probability that the behavior is present. It is suited for evaluation, guardrails, and monitoring of LLM and agent outputs at scale.

It is the higher-accuracy tier of the family. Span-01 Lite is the free, lighter tier.
