Grok Build is now available in the AI SDK harness layer
Vercel's AI SDK now abstracts Grok Build alongside Claude, OpenAI, and five other agent runtimes—write once, swap runtimes without refactoring.

Why it matters
A harness layer that decouples agent application code from underlying runtime choice reduces vendor lock-in and lets teams adopt Grok Build (xAI's coding agent) without rewriting. Relevant to practitioners building agent-native apps.
