low vram alternative/substitute of t5xxl, umt5xxl, etc.
80-90% smaller, better efficient and cost effective (hopefully)
rationale
since LLM in diffusion model basically serves as text encoder, which means its primary goal/function is delivering a prompt to the generator precisely, no talk, no deep reasoning, no long response, make it as simple as possible
limitation/cutoff
we stop the training when similarity reaches .95 or over 20k cycles and similarity no less than .75

how it works
simply replace --t5xxl t5xxl.gguf with --llm pig_clip-nvfp4.gguf --llm-adapter pig_t5_adapter-f16.gguf
