Vercel Labs Introduces Zero, a Systems Programming Language Designed So AI Agents Can Read, Repair, and Ship Native Programs
Vercel just shipped a programming language built FOR AI agents, not humans. Zero compiles to sub-10 KiB binaries and emits JSON so agents can repair code without touching a compiler.

Why it matters
This is infrastructure-as-product for agentic workflows. By making native code readable and repairable to AI systems, Vercel is removing a critical bottleneck in autonomous software engineering—compiler opacity. Leaders building agent-native stacks need to track this.
