Vercel 为 libfx 智能体引入持久化执行
Harness durability in https://t.co/OL0LzGtvAw.
Vercel CEO Guillermo Rauch 宣布，libfx 的 createFxAgent() 现已支持持久化，可在本地或云端通过文件、Postgres 或 Vercel Workflows 运行，兼容 Node.js 与 Bun。libfx 新增持久化适配器 API，在 Vercel 上借助持久化工作流与队列基础设施，1 行代码即可获得可靠性；进程在工具调用中途崩溃可从断点恢复。该能力后续将扩展到 Pi、OpenCode 及自定义 harness。

The same 𝚌𝚛𝚎𝚊𝚝𝚎𝙵𝚡𝙰𝚐𝚎𝚗𝚝() is now *durable* on your laptop or in the cloud, via files, Postgres, or Vercel Workflows. Node.js or Bun.
Agents need long-running compute. But they also need to tolerate restarts, redeploys, timeouts, crashes…
Concretely, if a user sends a prompt and then throws their phone into a black hole, we ensure that turn runs to completion. If the process crashes mid-tool-call, it resumes from there.
To this end, 𝚕𝚒𝚋𝚏𝚡 introduces a simple durability adapter API. On Vercel, it leverages all the infra we built for durable workflows and queues, giving you reliability with 1LOC.
This is a critical aspect of production-grade agents (and something all @eve agents also get out of the box). Next, we'll show you how we bring the same durability to Pi, OpenCode, and even your own custom harnesses.
