Quantized base weights and adapters have different roles

The central distinction is between storing the base model at lower precision and learning a smaller adaptation. Optimizer state, activations, and the training setup still consume memory, so weight size alone is not a complete training budget.

Measure quality after reducing training memory

Reduced memory does not guarantee identical behavior on your task. An original comparison should include both final accuracy and training stability, with the same held-out examples.

THE TAKEAWAY

What to remember

Compare accuracy after adaptation.
