Unsloth AI

Unsloth AI builds open source software that makes fine tuning and training large language models dramatically faster and less memory hungry. Its kernels and quantisation work let researchers train sizeable models on a single consumer graphics card, and its notebooks are among the most used entry points for practical fine tuning. The company maintains the library openly while offering a commercial version for teams that need scale and support; its library is downloaded millions of times and integrated into popular training stacks.
