Grok Build is now available in the AI SDK harness layer Vercel's AI SDK harness layer now supports Grok Build, an official adapter that runs through the same HarnessAgent interface as other coding-agent runtimes, allowing developers to switch runtimes without changing application code. The adapter, @ai-sdk/harness-grok-build, is built on the ACP harness adapter and joins Claude Code, Codex, Deep Agents, OpenCode, and Pi in the supported list. The AI SDK harness layer https://vercel.com/changelog/program-agent-harnesses-with-ai-sdk 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 https://vercel.com/changelog/use-acp-compatible-harnesses-with-the-ai-sdk-harness-layer @ai-sdk/harness-acp . Read the Grok Build harness documentation https://ai-sdk.dev/v7/providers/ai-sdk-harnesses/grok-build to get started. The full supported list of harnesses is now: Claude Code, Codex, Deep Agents, Grok Build, OpenCode, Pi, with more coming soon.
