User quantizes LTX-2.5 Gemma-4 12B text encoder for ComfyUI

By PulseAugur Editorial · [1 sources] ·

A user has developed a quantized version of the LTX-2.5 Gemma-4 12B text encoder, specifically optimized for ComfyUI. This new NVFP4 format reduces VRAM usage and functions as a direct replacement for the original encoder, with no apparent loss in quality. The user has shared the model on Hugging Face and is seeking feedback, particularly comparisons with the official INT8 ConvRot encoder. AI

IMPACT This optimization could lead to more efficient use of VRAM for users running Stable Diffusion models on ComfyUI, potentially enabling larger models or faster inference on less powerful hardware.

RANK_REASON User-developed optimization of an existing model for a specific tool.
