🤗 PEFT adds new LoRA merging methods: concatenation, linear, SVD, TIES

AI Impact Summary

🤗 PEFT now supports new merging methods for LoRA adapters, enabling on-the-fly composition of multiple adapters rather than full-model merges. This expands experimentation space and can improve deployment flexibility by letting teams mix and match adapters with different ranks and scaling factors. Be mindful of memory usage and compatibility when combining adapters (e.g., LoRA, IA3) and consider leveraging Diffusers' set_adapters for live activation. Overall, this shifts the workflow toward modular adapter management and faster performance tuning.
