- Quantized LoRA: load the base model in 4-bit precision, train LoRA adapters in 16-bit.

Quantized LoRA: load the base model in 4-bit precision, train LoRA adapters in 16-bit.

Fine-tune a 65B model on a single 48GB GPU — brought model customization to consumer hardware.

FSDP+QLoRA: scale across multiple GPUs for even larger models.

The democratization inflection point: anyone with a decent GPU can customize frontier-class models.
