You don't NEED to use the shunts, but it comes with the clip loaders that support the t5-unchained.These loaders work BECAUSE they essentially replace the original sd function calls with function calls directly linking utilization.For the shunts, you can use standard bert uncased or bert cased, instead of beatrix but the results won't be as accurate.Shunt code with unchained.<a target="_blank" rel="ugc" href="https://github.com/AbstractEyes/comfy-clip-shunts/tree/dev">https://github.com/AbstractEyes/comfy-clip-shunts/tree/dev</a>Full untrained unchained model:<a target="_blank" rel="ugc" href="https://huggingface.co/AbstractPhil/t5xxl-unchained">https://huggingface.co/AbstractPhil/t5xxl-unchained</a>I have a ton of clips loaded here.

It's treated as though the T5xxl's lora_te3 is the "T5xxl" text encoder. I've extracted the lora_te3 layers from the original sd35 trained lora and resaved. Simple process really, no telling what sort of defectiveness it has. I doubt it'll load in anything but comfyui or forge, but here it is.You can have a conversation with the loaded T5xxl-unchained with the lora weights applied; using standard LLM inference if you like. It'll summarize pretty well.800 meg lora.

The newest T5 is still training.Requires the correct tokenizer and config for the T5xxl and the T5xxl model weights to function.<hr />Without the base t5xxl-unchained, tokenizer, and correct dimensions configuration; you will receive a size mismatch error.You need the big ass T5xxl fp16 or fp8. It was trained in fp16 so you'll get better results from the finetune with it. You can probably just tell comfyui or forge to downscale it.<a target="_blank" rel="ugc" href="https://huggingface.co/AbstractPhil/t5xxl-unchained/resolve/main/t5xxl-unchained-f16.safetensors">https://huggingface.co/AbstractPhil/t5xxl-unchained/resolve/main/t5xxl-unchained-f16.safetensors</a>When the clip-suite is ready, it'll automatically scale in program and allow hardware-level quantization hot-conversion (Q2, Q4, Q8, etc) utilization, and saving within ComfyUI.At that point you'll only need one model and everything will just convert at runtime using the META C++ libs.<a target="_blank" rel="ugc" href="https://huggingface.co/AbstractPhil/t5xxl-unchained/blob/main/config.json">https://huggingface.co/AbstractPhil/t5xxl-unchained/blob/main/config.json</a><a target="_blank" rel="ugc" href="https://huggingface.co/AbstractPhil/t5xxl-unchained/blob/main/tokenizer.json">https://huggingface.co/AbstractPhil/t5xxl-unchained/blob/main/tokenizer.json</a>To modify Forge you can swap these files with the ones at the address; the only exception being the sd3_conds.py needing a direct modification to the template contained within code.Make a backup of the original configs if you want.

T5xxl-Unchained Lora + Workflow

This is a T5xxl exclusive lora that can be loaded into comfyui; the first of it's kind - tested with the most recent version of comfyui with the t5xxl loaded with the triple clip loader. The only weights that exist are based on the T5xxl.It will work with any T5xxl based model; assuming the T5xxl unchained does work.The effect on the standard T5 is undocumented and untested; so I wouldn't advise playing with fire.
