PickyTrain Edits GGUF Weights Directly
π‘New OSS tool for direct GGUF weight editsβno GPU needed
β‘ 30-Second TL;DR
What Changed
Edit weights by layer/row/col with warnings for coupled tensors like ffn_gate/up/down
Why It Matters
Democratizes fine-grained model surgery for experimentation without full retraining. Bridges gap between running models and heavy fine-tuning for local LLM tinkerers.
What To Do Next
Clone PickyTrain GitHub repo and test editing a Q4_K GGUF Llama model tensor.
Key Points
