GaLore: Memory-Efficient LLM Training by Gradient Low-Rank Projection 

Large language models (LLMs) typically demand substantial GPU memory, rendering training impractical on a single consumer GPU, especially for a 7-billion-parameter model that necessitates 58GB of memory. In response, the GaLore paper introduces an innovative strategy that projects gradients into a low-rank space, enabling the model to fit within the constraints of a single GPU. Remarkably, this approach not only addresses the memory challenge but also outperforms other parameter-efficient tuning methods like LoRA, delivering superior results.
