开源 vs 封闭，里约市用 Qwen 做示范
Hugging Face CEO Clement Delangue 在推文中强调 AI 发展没有必然性，所有人都有选择权。他对比两条路径：封闭 API 导致权力集中，或开源 AI 让所有人参与。他引用 SemiAnalysis 的案例：里约热内卢市基于 Qwen 7/2 后训练了 Rio 3.5 Open 397B 模型，该模型采用 SwiReasoning 框架，动态切换标准链式推理和隐空间推理，通过熵置信信号提升 token 效率。

There is no inevitability in AI. We all have agency in what comes next: Path 1: closed-source APIs, concentration of power, and a future decided by a handful of people in Silicon Valley and DC Path 2: open-source AI, where everyone gets to participate, own, and build together, including orgs like the city of Rio. Pick your path anon! SemiAnalysis @SemiAnalysis_ SITUATION DETECTED: The city of Rio de Janerio has post-trained a model. Based on Qwen 7/2, Rio 3.5 Open 397B adds SwiReasoning on top of the base Qwen model — a framework that dynamically switches between standard chain-of-thought and latent-space reasoning, guided by entropy-based confidence signals, so the model only "thinks out loud" when it needs to and otherwise reasons silently in hidden space for better token efficiency. 🔗 View Quoted Tweet 💬 9 🔄 8 ❤️ 78 👀 3593 📊 14 ⚡
