为更长的 agent 运行提升 token 效率 · Cursor
这一现象在各类模型家族中均成立,系统提示词因此减少了约66%。
原始摘录
This was true across model families, allowing us to trim roughly 66% of our system prompt.
上下文
随着模型能力提升,大部分指令性内容已不再必要:我们无需再写冗长的‘切勿执行此操作’‘必须执行’或‘重要’等说明,只需清晰定义工具行为,模型通常即可正确执行。
原始上下文
As models improved, much of that direction became unnecessary. Instead of long lists of "DO NOT do this," "You must," or "Important" instructions, we could simply define how a tool behaves and models would generally comply.
