FLAN-T5-XXL Fused Model
This repository contains a fused version of FLAN-T5-XXL, combining the split files available at Google's FLAN-T5-XXL repository. These files have been merged for easier use in AI applications, including image generation models.
Newly Added: TE-Only Models for Stable Diffusion WebUI Forge & ComfyUI (2025-03-04)
Two additional files provide the Text Encoder (TE) only portion of FLAN-T5-XXL, specifically extracted for use with Stable Diffusion WebUI Forge and ComfyUI.
flan_t5_xxl_TE-only_FP32.safetensors
: Full-precision FP32 TE-only model.flan_t5_xxl_TE-only_FP16.safetensors
: Half-precision FP16 TE-only model for memory-efficient inference.
These models retain only the text encoding functionality of FLAN-T5-XXL, reducing resource consumption while maintaining high-quality prompt processing in AI image generation workflows.
Also can be used as drop-in replacements for standard text encoders in Stable Diffusion-based workflows.
