Pi重构Agent执行层：长任务开始走向持久化运行

Pi重构Agent执行层：长任务开始走向持久化运行

2026-08-11 18:15

ChainThink 消息，8 月 11 日，Pi 正在重构 Agent Harness 执行层，最新 Harness v3 规范已完成并进入最终审计阶段。

该版本重做任务执行和存储机制，使 Agent 在进程崩溃或 Harness 升级后，可从中断处继续运行。

Pi 是 Mario Zechner 创建的开源 Agent Harness，最早因 OpenClaw 使用而受到关注。

今年项目被 Earendil 收购，Mario 也加入公司继续负责开发。

目前 Pi 已获得超过 6 万 GitHub Star，MiniMax 最新的 MiniMax Code 也明确基于 OpenCode 和 Pi 搭建 Harness。

Harness v3 将在模型请求和工具调用前保存执行状态，完成后再写入结果。重启后，Pi 可识别哪些任务已完成、哪些可重跑、哪些因存在副作用不能重复执行；

对话、运行状态和 Token 成本也将分开保存，并加入跨版本状态迁移。随着 Claude Code、Codex 等 Agent 产品向更长时间任务推进，持久化运行能力成为关键基础设施之一。

OpenAI 已研究如何让 Codex 持续完成长时间工作，Anthropic 也称 Claude Code 正更多用于长时间运行的 Agent 任务。
