## AI overview

Vercel has added Grok Build to the AI SDK harness layer, allowing it to run through the same HarnessAgent interface as other supported coding-agent runtimes. The official Grok Build adapter is built on the ACP harness adapter.

## Source excerpt

The AI SDK harness layer lets you run established coding-agent runtimes through one unified interface, so you can switch runtimes without changing your application code. Today we are adding Grok Build, which runs through the same HarnessAgent interface as every other supported harness. @ai-sdk/harness-grok-build is the official harness adapter for Grok Build, built on top of the ACP harness adapter (@ai-sdk/harness-acp). Read the Grok Build harness documentation to get started. The full supported list of harnesses is now: Claude Code, Codex, Deep Agents, Grok Build, OpenCode, Pi, with more coming soon. Read more
