RT-DETRv4: Real-Time Detection Transformer

RT-DETR (Real-Time Detection Transformer) is a real-time object detection model repackaged for use in ComfyUI. Despite being stored in diffusion_models, this is an object detection model — not a diffusion/ generation model. It is designed for ComfyUI custom nodes that load detection models from the diffusion_models directory.

Usage in ComfyUI

Place the model files in ComfyUI/models/diffusion_models/. The model is loaded by ComfyUI custom nodes that support RT-DETR-based object detection.
