A DeepSeek-native agent
for your terminal. DeepSeek 原生的
终端编码 Agent。
The loop is append-only, aligned to DeepSeek's byte-stable prefix cache — so long sessions hold 90%+ cache hit and input-token cost collapses to ~1/5. Terminal-first. 运行循环 append-only,对齐 DeepSeek 字节稳定的 prefix-cache —— 长会话缓存命中 90%+,输入 token 成本降到 约 1/5。终端优先。
Built for long, cheap sessions.为长会话、低成本而生。
Most agents pay full price for the same growing prompt every turn. Reasonix keeps the prefix byte-identical so DeepSeek's cache does the heavy lifting — and everything else follows.多数 agent 每回合都为同一段不断增长的 prompt 付全价。Reasonix 让前缀逐字节稳定,让 DeepSeek 的缓存替你扛下来——其余一切由此而来。

Append-only history aligned to DeepSeek's prefix cache. 90%+ hit on long sessions; input tokens bill at ~1/5.append-only 历史对齐 DeepSeek prefix-cache。长会话 90%+ 命中,输入 token 约 1/5 计费。

Terminal-native终端原生
Not another IDE plugin. git diff handles diffs, ls handles trees — the terminal is the workspace.不是又一个 IDE 插件。diff 交给 git diff,树交给 ls —— 终端就是工作面板。
$ ssh build-box → reasonix code Every turn reuses the last.每一轮都复用上一轮。
Each request replays the exact same byte-for-byte prefix, so the model only computes what's new. Long sessions get cheaper per turn — not more expensive.每次请求都逐字节重放完全相同的前缀,模型只计算新增部分。会话越长,每轮越便宜——而不是越贵。

One command. macOS, Linux, Windows, and WSL.一条命令,支持 macOS、Linux、Windows 与 WSL。

Reasonix maps the codebase once, then keeps that map in the warm prefix.Reasonix 只做一次代码库测绘,然后把这份地图常驻在温热的前缀缓存里。
cd your-project && reasonix code Leave it running让它一直跑着
Queue tasks, review diffs, resume anytime. The session never goes cold.排任务、看 diff、随时恢复。会话永不冷却。
