Hey! If you're interested to try out finetuning Llama-3 8B (Meta's new 15 trillion token!! model), made a Colab to finetune Llama-3 2x faster and use 60% less VRAM, and supports 4x longer contexts than HF+FA2.
Also uploaded Llama-3 70b pre-quantized 4bit so you can download it 4x faster! unsloth/llama-3-70b-bnb-4bit
