ZenTrainer 0.4.0: open-source LoRA trainer runs inside ComfyUI for image and video models
Nynxz · reddit · 2026-10-31
Developer Nynxz released ZenTrainer 0.4.0, a free, MIT-licensed LoRA trainer that lives inside ComfyUI and handles both image and video models.
Key features
- Train from a ComfyUI tab: pick a model, drop in pictures, and it auto-fills files, captions, and settings
- Live previews during training plus a per-checkpoint likeness score for character LoRAs
- Works on NVIDIA and AMD (ROCm) on Linux and Windows, reusing models already in ComfyUI
End-to-end validated models: MOSS Image, Krea 2, Fibo 2.0, FLUX 3 Image, FLUX.2 Klein 9B, Qwen Image 2.1, Z-Image, Anima, SDXL (including Pony, Illustrious finetunes), and MiniMax H3 for video.
Install via ComfyUI Manager (search "ZenTrainer") or run with its own pinned ComfyUI so updates never break a run.
