scroll 0 1 9月15日前后，一个名叫Jev的新模型突然在硅谷AI开发者社区刷屏。
它颠覆了大家对当下大模型的认知，不会写代码、写文章甚至是聊天，主动砍掉了过去几年大模型最重要的一项能力——生成文字，只保留“判断”。TypeSafe给它的定义是：“Decisions,not strings”——要决策，不要文本。

给它一段信息和几个提前定义好的问题，它可以直接返回选择、评分以及相应概率。例如收到一封客服邮件，Jev可以同时判断应该分给哪个部门、紧急程度、退款风险以及是否需要人工介入。
这个看起来更像“高级分类器”的模型很快获得关注。Latent Space在9月16日的AINews中称，TypeSafe发布当天长时间位于Hacker News前列，创始人DiogoAlmeida的发布帖当时已有约420万次浏览、近2万次点赞。
TypeSafe公布的性能数字也很夸张：在特定工作流评测中，Jev最高比对照大模型快193.6倍、便宜444.6倍，端到端延迟70—500毫秒，输入价格每百万Token0.042美元，输出不按Token收费。
Jev背后的团队同样也是自带流量。它来自刚刚走出隐身模式的旧金山创业公司TypeSafe AI，由DiogoAlmeida、Erik Gafni和SashaSheng共同创立，刚完成DCVC领投的4000万美元种子轮融资，Forbes援引知情人士称估值约2亿美元。
