DIY Spectrum Implementation for LTX-2.5: CFG and Negative Prompting Give Modest Gains
8RETRO8 · reddit · 2026-09-27
Reddit user 8RETRO8 implemented Spectrum sampling for the LTX-2.5 base model to test how much quality boost CFG and negative prompting could deliver.
The verdict: not much on the base model, but it seems more useful inside an IC-LoRA upscale workflow. Test observations and workflow configuration advice are collected in a public repo for anyone to reproduce.
