Detected Models

• upscale_model: 4x_NMKD-Siax_200k.pth -> models/upscale_models
• clip: t5-v1_1-xxl-encoder-Q8_0.gguf -> models/clip
• vae: ae.safetensors -> models/vae

Runtime Warnings

• Large model(s) detected; ensure enough VRAM and disk space.
• Medium-high resolution detected; expect moderate extra runtime.
• Uses custom nodes; missing nodes can cause validation/runtime failures.
