Reason Machines 刚刚推出了 Reason，这是一款封装 GPT-6 Astra 等单一模型的编程代理框架，完成任务的成本比 OpenAI 的 Codex 低 22%。
原理：传统编程代理每一步都会把上下文重新发送给模型，因此 Reason 缩减了这部分负载：
Reason 在各轮对话中保持提示词前缀完全一致：它把固定指令和简短的工具列表放在每次提示词的开头，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。
由于每轮都以完全相同的文本开头，OpenAI 会将其识别为上一轮已出现的内容，对这些重复 token 的收费降低 90%，每百万个从 10 美元降至 1 美元。

Reason Machines just launched Reason, a coding harness that wraps a single model like GPT-6 Astra and solved tasks 22% cheaper than OpenAI’s Codex. How: A traditional coding agent resends its context to the model on every step, so Reason trims that load: Reason holds the prompt prefix identical between turns, by putting its fixed instructions and small tool list at the top of every prompt and only adding new code and results at the end, never rewriting or reshuffling the earlier text. Since every turn starts with the exact same text, OpenAI recognizes it from the previous turn and bills those repeated tokens 90% cheaper, at $1 instead of $10 per million.
以前沿编程性能实现最高 20 倍的成本降幅。
推出全球成本效益最高的代理框架：Reason
别再为失控的代理账单花费数千美元。
Reason 在 Terminal-Bench 和 DeepSWE 上的表现优于顶尖代理框架，同时将每项任务的成本降至前沿基准水平的一小部分。
