把 agent 决策节点换成 Jev 的架构讲解
视频主张 agent 不该用生成模型做决策：Jev 输出带 schema 的类型化决定（用哪个工具、继续还是停、是否转人工），成本约为前沿模型的 1/200。
There's a new AI model that doesn't generate text. it just decides. and that one difference is about to change how every AI agent is built. every agent you've used runs on the same architecture: action needed → call GPT or Claude → parse the text response → execute. slow. expensive. and one hallucinated tool call breaks the whole chain. Jev replaces that middle step: not "here's my answer in text". just - use this tool. stop here. escalate to human. execute now. typed decisions. schema-guaranteed. 0% structured output errors. what that means for agents: every decision node that used to be a frontier LLM call becomes a Jev call. which tool to use, whether to continue or stop, when to hand off to a human. the frontier LLM stays in the pipeline. it handles the steps that actually need generated text. Jev handles everything else. at 1/200th the cost. the agents we're building today are expensive because we're using content generators to make decisions. that's the wrong tool for the job. and now there's a right one.
