Inputs

Optional runtime overrides supported by run(...):
- prompt
- negative_prompt
- width, height
- seed, steps, cfg
- sampler_name, scheduler, denoise
- server, headers, api_prefix

Outputs

Returns JSON with:

Model Requirements

diffusion_model: wan2.1_i2v_480p_14B_fp8_scaled.safetensors -> models/diffusion_models
clip: umt5_xxl_fp8_e4m3fn_scaled.safetensors -> models/clip
vae: wan_2.1_vae.safetensors -> models/vae
lora: muscle_18_epochs.safetensors -> models/loras

Custom Node Requirements

Routing Metadata

Family: video_t2v_i2v_avatar
Input modalities: image, text_prompt
Output modalities: video/mp4
Model families: wan
Node count: 17
Complexity score: 8
Resource profile: high
Estimated runtime: slow (often 2-6 min depending on model/server load)
Max latent resolution hint: NonexNone
Max sampler steps hint: 30

Detected Models

diffusion_model: wan2.1_i2v_480p_14B_fp8_scaled.safetensors -> models/diffusion_models
clip: umt5_xxl_fp8_e4m3fn_scaled.safetensors -> models/clip

Runtime Warnings

Large model(s) detected; ensure enough VRAM and disk space.
Uses custom nodes; missing nodes can cause validation/runtime failures.
Video workflow: usually slower and VRAM-intensive than still-image workflows.
