Can I train multiple adapters without retraining the base model?

Yes, this skill includes implementation patterns for multi-adapter hot-swapping, allowing you to load lightweight adapters onto a single frozen base model at inference time.

What is the recommended alpha scaling for QLoRA?

Generally, setting alpha equal to the rank (1.0x scaling) is the standard for a balanced training. You can use alpha=2r for more aggressive convergence if the learning rate is adjusted accordingly.

How much memory does 4-bit NF4 quantization save?

4-bit NF4 quantization typically provides 11-15% memory savings compared to BF16 while maintaining nearly identical model quality, making it ideal for memory-constrained environments.

Which target modules should I use for knowledge injection?

Use 'mlp_only' (gate, up, and down projections) to focus on factual knowledge injection, whereas 'attention_only' is better for changing reasoning styles or formatting.
