# ComfyUI-DiffiT

This node pack now exposes a single node only:

- `DiffiT Official Image`

It loads the official DiffiT checkpoint, creates latent noise from `seed`, samples with the official pipeline path, decodes with the selected VAE, and outputs `IMAGE`.

## Class IDs ITS A LIE dont use 0 

`class_id` is zero-based:

- `1` = tench
- `2` = goldfish
- `3` = great white shark

## Install

```powershell
C:\Users\xcool\AppData\Roaming\StabilityMatrix\Packages\ComfyUI-rect\venv\Scripts\python.exe -m pip install -r C:\Users\xcool\AppData\Roaming\StabilityMatrix\Packages\ComfyUI-rect\custom_nodes\ComfyUI-DiffiT\requirements.txt
```

Restart ComfyUI after install.

## Weights

Preferred Stability Matrix path:

`C:\Users\xcool\AppData\Roaming\StabilityMatrix\Models\DiffusionModels`

Fallback ComfyUI path:

`C:\Users\xcool\AppData\Roaming\StabilityMatrix\Packages\ComfyUI-rect\models\diffusion_models`

Required filenames:

- `diffit_256.safetensors`
- `diffit_512.safetensors`

## Defaults

- `steps=250`
- `scale_pow=4.0`
- `cfg_scale=4.4` for `diffit_256.safetensors`
- `cfg_scale=1.49` for `diffit_512.safetensors`
- `cfg_cond=True`
- `use_ddim=False`
