Chai launches Workers IO: millions of fault-injected simulations to verify agent-written code
julianweisser · x · 2026-11-03
Chai's founder announces Workers IO, targeting the slowest part of engineering: verification.
- AI agents now write years' worth of code in days, but verification still takes significant effort, and the costliest failures surface in production
- Workers IO runs millions of simulated production scenarios across your entire system including dependencies, inside a deterministic hypervisor that injects faults like network delays, disk errors, clock skew, and process failures
- Deterministic execution makes failures reproducible and predictable before shipping
