AI SDK has always let you switch models without rewriting your agent. Now you can switch the harness the same way. AI SDK 7HarnessAgentWrite the agent once. Use the best harness available. Today. In 3 months. A year from now. Harnesses manage the components above a model call, including skills, sandboxes, sessions, permission flows, compaction, runtime configuration, and sub-agents.
The AI SDK normalizes access to those capabilities through a unified harness abstraction. Initial harness adapters for this experimental release include Claude Code, Codex, and Pi, with more coming soon. Swap for or and keep the same flow. Every harness runs the agent in a sandboxed workspace, keeping the host environment safe. claudeCodecodexpiHarnessAgentBoth and return AI SDK-compatible results.
