ChatGPT 发明者推出非语言模型 Jev，开发者反响热烈
原标题：A new kind of AI model from a ChatGPT inventor is thrilling developers
AI 摘要
ChatGPT 与 RLHF 发明者之一 Diogo Almeida 离开 OpenAI 后创办 TypeSafe AI，本周发布非语言模型 Jev。Jev 基于 transformer，不输出文本而是输出概率（校准决策），因此成本极低、速度快且不会幻觉。开发者反馈其在分类、安全审查等自动化任务上比 ChatGPT Luna 5.6 快 5 至 18 倍，比 Gemini 便宜 10 至 20 倍，可用于替代或监督 LLM、模型路由等场景。

But despite its capabilities, he was disappointed. “We have lightning in a bottle, and yet it is not useful,” Almeida told TechCrunch. “I’ve been battling that problem since then. It took me a while to come to the conclusion: The problem is we are optim
