RespanAI 开源权重决策模型 Span-02 上架 OpenRouter
RespanAI 的开源决策模型 Span-02 上 OpenRouter 了，$0.01/M token 还免输出费，自带 Rust 引擎比 vLLM 快 7 倍，做分类判断挺合适。
RespanAI 的 Span-02 是一个开放权重决策模型，输入文本和图片与自定义问题，输出选项、yes/no/unknown 判断或评分，并附带概率。定价为 $0.01/M 输入 token，输出免费，上下文 131K，是当前最便宜的决策模型。支持设定推理预算，可随时提前停止推理，auto 模式下由自适应学习门控自动分配每个决策的推理预算。模型权重完全开放，附带 Rust 推理引擎，速度比 vLLM 快 7 倍。
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 💬 5 🔄 5 ❤️ 18 👀 1225 📊 6 ⚡
