How are we faster?
By manually deriving all compute heavy maths steps and handwriting GPU kernels, Unsloth magically makes training faster without any hardware changes.
1 GPU or 100 GPUs
10x faster on a single GPU and up to 30x faster on multiple GPU systems compared to Flash Attention 2 (FA2).
We support NVIDIA GPUs from Tesla T4 to H100, and we’re portable to AMD and Intel GPUs.
Don’t believe us?
Why not try our fully free open source version? Finetune 2X faster on a single NVIDIA GPU for free on Google Colab or Kaggle Notebooks.
