Chai launches Workers IO: deterministic hypervisor runs millions of simulated scenarios to verify agent-written code
julianweisser · x · 2026-11-03
Chai announces Workers IO, targeting verification — the slowest part of engineering now that agents can write years' worth of code in days. The most expensive failures are still found in production.
Workers IO runs millions of simulated production scenarios against your entire system including dependencies, inside a deterministic hypervisor that injects faults like network delays, disk errors, clock skew, and process failures to verify how the system handles them.
