Respan Span
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.
Span-01 has a 4K context and runs on the Respan gateway and OpenRouter; Span-01 Lite is free and Pro is $0.02 per 1M input tokens. Span-02, released October 15, 2026, has open weights and costs $0.01, output free. Respan is the trading name of Keywords AI Inc., California.
