Span-02 from @RespanAI is now on OpenRouter An open-weight decision model: give it text and images, define your questions, and get back a choice, a yes/no/unknown, or a score, with probabilities. $0.01/M input tokens, free output, 131K context. Respan @RespanAI Span-02 is the cheapest decision model: $0.01/M input tokens. With thinking off, it delivers frontier-level decision-making at lowest latency. Need more? Give it a reasoning budget. Span-02 thinks until the deadline, then returns its best decision so far. Stop reasoning anytime. Or let Span-02 decide. In auto mode, an adaptive learned gate picks the reasoning budget for every decision. Fully open weights with a rust inference engine. 7× faster than vLLM. 🔗 View Quoted Tweet
