Behavior scoring model: the probability that each plain-language behavior you define is present in a conversation

Span-01 is Respan's behavior scoring model. It reads a conversation span and returns, for each plain-language behavior you define, the probability that the behavior is present. That makes it a decision model aimed at evaluating agent and chat transcripts rather than general routing.

It has a 4K context and is available on the Respan gateway and through OpenRouter. Span-01 Lite is a free, lighter tier.

The Pro route is priced at $0.02 per 1M input tokens, with output free. Respan is the trading name of Keywords AI Inc., California.
