Vercel's durable-harness makes Pi, OpenCode, and Codex resumable

AIGuillermo Rauch says Vercel is extending its Workflows durability infrastructure to all agent harnesses, including Pi and OpenCode, in a runtime-agnostic open-source solution. He adds that Claude Code and Codex can be made durable and observable this way, but they are not currently designed for embedding, making them less efficient and portable and requiring an extra sandbox.

Much like we did with @aisdk, we're bringing a truly open-source, runtime-agnostic solution to harness durability.

We're extending the durability infra that powers @eve and Workflows to all harnesses, like Pi and OpenCode. Local, Vercel, or DIY.

Fun fact: even Claude Code and Codex can be made durable (and observable!) this way. The catch: they're not (currently) designed for embedding, which makes them less efficient, less portable, and brings an extra sandbox requirement compared to Pi or Fx.
