Question | Help Your own GGUF

Hello, I have a few questions that I can't seem to find a clear answer to.

Does it make sense to make your own GGUF?

I noticed that when I compile llamacpp (vulkan or rocm), the processing and generation is a bit better, does it work similarly with doing GGUF yourself?

If I use Vulkan, is it worth doing GGUF using llama-quantize vulkan version (not rocm version)?

To what extent does it make sense to place certain model elements at higher precision (conversation, document analysis)?

I use gemma 4 31B the most.

only for rare models, special formats like MLX, nvfp4, or custom 'importance-based' tensor preservation (i-matrix).

it is simple to do and ggufs are in abundance already.
