How Cloak chooses a local model

Cloak chooses a supported model for the job and your Mac.

What “move it local” means

Cloak checks inputs, outputs, and surrounding code. Safe jobs try local first and keep the cloud fallback; unsafe jobs are unchanged.

What Cloak handles for you

Cloak traces the call, chooses a model, rewrites the integration, adds fallback, and tests the result.
