Is your feature request related to a problem? Please describe.
I initially want to add our recently published BEFT (paper) (ACL2026 Main Conference) as a sft/peft method in Tunix. However, I found that the current tunix-LoRA is provided from qwix, as shown here. Moreover, in peft_trainer (link), the lora option is provided from flax.

Therefore, I am wondering that where is the best place for contributing other sft/peft methods?

Describe the solution you'd like
Alternatively, will Tunix provide the direct interface for intergrating more sft/peft methods?

Additional context
I wish get some guidance. Thank you in advance @tianshub @s-noghabi
