The code for both is usually very similar, and the overall process looks almost the same.</p> <p>The key difference between training from scratch and fine‑tuning a pretrained model is how the weights are initialized. When we fine‑tune a model, we start from weights that already capture useful patterns instead of initializing everything randomly. In other words, the model does not begin from zero knowledge.</p>
