Key Info

RespanAI's open-weight Span-02 decision model is now available on OpenRouter. It accepts text and images, and returns a choice, a yes/no/unknown answer, or a score with probabilities.

Highlights

  • Pricing: $0.01 per million input tokens, free output, 131K context window.
  • With thinking off, it delivers frontier-level decision-making at lowest latency; a reasoning budget can be set to let it think until a deadline.
  • Runs on the OpenRouter Decisions API with the same request format as other hosted decision models, so switching is a one-line model change.
  • Images go in the same state as text, up to 4 per request.
