That can be effective, but storing and serving a separate full checkpoint for every task becomes expensive as model size and task count grow. Prefix tuning offers a different arrangement: keep the pretrained model frozen and train a small set of task-specific states that participate in attention.</p> <p>This article builds a practical mental model for prefix tuning, shows how it differs from text prompts and low-rank weight adapters, and explains the trade-offs that matter when training or serving several task variants.</p>
