旧金山初创公司TypeSafe AI发布新型AI模型Jev，专用于回答是/否及多项选择题，并给出置信度评分。它不生成文本，直接输出结构化决策结果供程序使用，适用于软件开发中的系列决策任务，号称比大语言模型快10倍、成本仅为其十分之一。
TypeSafe AI推出Transformer模型Jev，绕开大语言模型文本生成范式，以概率输出和“校准决策”服务软件自动化。创始人Diogo Almeida曾任OpenAI研究员，认为语言优化模型不适合计算机自动化。Jev不生成文本只输出概率，规避幻觉与冗余成本；输出标记免费，输入按十亿级标记计费。
TypeSafe AI的首个System One Model Jev，赋予AI代码属性。
