The small, accessible Bernini-R for ComfyUI. This repo is self-contained — the 1.3B renderer plus the VAE and text encoder it needs — so you can edit images/video on modest GPUs. It's the lightweight sibling of the 14B GGUF repo (that one is full quality for 24 GB cards).

Bernini-R 1.3B is single-expert (fine-tuned from Wan2.1-T2V-1.3B — no high/low MoE), so it's tiny (~2.6 GB) and runs almost anywhere. It performs close to the 14B on simpler edits (style transfer, watermark/subtitle removal, local editing) and lags on the hardest tasks.

Usage in ComfyUI

Install ComfyUI-BerniniR and ComfyUI-GGUF (required — the graphs load the text encoder with CLIPLoaderGGUF).
Drop each file in the folder from the table above.
Load the workflow workflows/bernini_i2i_1.3B.json (or grab it from the node repo). It's a single-expert graph — no model_low. Put your image, run.
- Renderer — native (bf16): BerniniR · Load Model (native). GGUF: UnetLoaderGGUF → BerniniR · Apply Patches → Source Stream → Guider (leave model_low empty).
- Text encoder: CLIPLoaderGGUF (type = wan) → umt5-xxl-encoder-Q5_K_M.gguf. The graphs default to the GGUF encoder because the fp8 .safetensors one triggers a Windows / torch-2.8 access violation under memory pressure; the fp8 file is kept only as an optional fallback.

Use the 14B dual-expert GGUFs: neuregex/Bernini-R-GGUF. Same nodes, just wire both experts into the guider (model = high, model_low = low).
