Rein
5 行代码,把任意大模型变成能调工具、自己循环干活的 agent。
Rein 是一个极薄但生产级的单-agent harness(智能体运行时)框架。反 LangChain 式的重抽象,聚焦把"单 agent 的 loop + 工具 + 可控 + 可观测"做到极致。
安装
pip install rein-agent # 装完即接入真实大模型(100+ 厂商,经 LiteLLM)
快速开始
from rein import Agent
agent = Agent(model="anthropic/claude-opus-4-8")
@agent.tool
def read_file(path: str) -> str:
"读取文件内容"
return open(path).read()
print(agent.run("读 README 并总结"))
核心特性
- 多厂商:wrap LiteLLM,一行切换 100+ 厂商模型 + 自动 fallback
- 可序列化状态机:Loop 状态全在可序列化 Session 里 → 天生支持 HITL 人工审批、断点续跑
- 熔断四道闸:轮数 / token / 超时 / 重复检测,防 agent 失控烧钱
- 并发安全:Agent(无状态蓝图)/ Session(状态)/ Chat(会话句柄)三者分离
- 可观测:结构化
RunResult+ 可选 OpenTelemetry 导出 - 可扩展:中间件 / 钩子 / 事件 / Docker 沙箱 / 插件
- 脚手架:
