用 System 1 / System 2 类比解释 Jev 适合做什么
把 Jev 比作大脑的直觉系统：处理路由工单、标记风险内容、给线索打分这类每天上千次的小判断，比聊天模型快约 100 倍、成本更低。
for all my nontechnical peers who have been hearing about Jev lately but don't know how it works or what it's useful for, here is the simplest way to understand: our brains have 2 systems: System 1 is the gut-based, reactionary mode for quick decisions and System 2 is for tasks that require deliberate thinking and consideration most AIs you currently use are System 2 models where your outputs are in some format that requires creative thinking (most common form is a paragraph of text) but a lot of our real-world AI work isn't chat-based. It's thousands of tiny judgment calls a day like routing support tickets, flagging risky content, or scoring leads so, using a system 2 model for these tasks is like hiring a novelist to sort your mail Jev is able to do these tasks ~100x faster at a fraction of the cost its only drawback is that it's closed, so the team at @interfaze_ai built an open-source version called Lev, free for anyone to run, inspect, and fine tune (see comments)
