Reason Machines launches Reason coding harness, claims lower task costs than CodexMachine translation

AI introduction

Reason Machines launched Reason, a coding harness that keeps the prompt prefix unchanged across turns so repeated content qualifies for cached-token pricing. The source says it solved tasks 22% cheaper than OpenAI’s Codex; early access is offered to people who comment “Reason.”

Reason Machines 刚刚推出了 Reason,这是一套围绕 GPT-6 Astra 等单一模型构建的编程智能体框架,完成任务的成本比 OpenAI 的 Codex 低 22%。

其原理是:传统编程智能体在每一步都会将上下文重新发送给模型,因此 Reason 减少了这部分负担:

Reason 将固定指令和简短的工具列表放在每次提示的开头,只在末尾添加新的代码和结果,从不改写或重新排列之前的文本,从而使各轮对话的提示前缀保持完全一致。

由于每轮都以完全相同的文本开头,OpenAI 会识别出上一轮出现过的内容,并对这些重复的 token 按低 90% 的价格计费:每百万个从 10 美元降至 1 美元。
