SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Running ComfyUI generation jobs from OpenMontage requires correct server configuration, API-format workflow exports, output node selection, and model placement, and mistakes in any of these cause failed or unreproducible generations. ## Core Features & Use Cases - Workflow Selection and Execution: Choose between bundled workflows and custom workflow_json/workflow_path inputs for comfyui_image, comfyui_video, and comfyui_music, including low-VRAM options like Wan 2.1 1.3B, LTXV FP8, and GGUF quantized workflows for 8GB-12GB GPUs. - Output Node and Model Management: Identify the correct terminal saver node (SaveImage, SaveVideo, VHS_VideoCombine, SaveAudioMP3), place diffusion models, text encoders, VAEs, and LoRAs in the expected ComfyUI model folders, and handle structured missing_models responses. - Failure Recovery and Provenance: Resume timed-out jobs with resume_prompt_id, record workflow_name, workflow_model, and workflow_model_stack for reproducibility, and distinguish hosted Partner Nodes from local open-weight paths. - Use Case: A user imports a community Wan 2.2 GGUF video workflow, passes it as workflow_path with output_node set to the VHS_VideoCombine node ID, and the tool reports any missing models with download hints before generating. ## Quick Start Use the comfyui skill to generate a short video with the bundled Wan workflow, or run my custom workflow file with the correct output node selected.

Frequently Asked Questions about comfyui

FAQPage Schema
How do I use a custom ComfyUI workflow in OpenMontage?▼

Export the workflow from ComfyUI in API format, then pass it as workflow_json or workflow_path along with output_node set to the terminal saver node ID as a string. UI-layout JSON exports will not submit and must be re-exported with API format enabled.

How do I choose the output_node for a ComfyUI workflow?▼

Pick the node that writes the final artifact, typically SaveImage, SaveVideo, VHS_VideoCombine, or SaveAudioMP3 for music. Pass the node ID as a string like "108", not the class name, and prefer the final deliverable node over previews.

Which ComfyUI workflows work on 8GB to 12GB GPUs?▼

Lower-footprint options include Wan 2.1 1.3B, LTXV FP8 or quantized workflows, and Wan 2.2 GGUF community workflows. The bundled Wan 2.2 14B FP8 video workflows target 16GB-class hardware, so they are not suitable for smaller GPUs.

Why does my ComfyUI generation fail with missing models?▼

The workflow references model files not present in the expected ComfyUI folders. Read the structured data.missing_models payload for each file's name, role, destination hint, and download URL, then place models under diffusion_models, text_encoders, vae, or loras as required.

What happens when a long ComfyUI render times out?▼

A timeout is recoverable: check ComfyUI history first, since the server may have finished the job. Otherwise call the tool again with resume_prompt_id set to the prompt_id from the timeout error to resume waiting without resubmitting.

Are ComfyUI Partner Nodes like seedance_2.5 free and local?▼

No. Partner Nodes such as gemini_omni_flash, seedance_2.5, and minimax_h3_api call hosted APIs and require network access, a logged-in Comfy account, and prepaid credits. The minimax_h3_local path is the separate open-weight alternative.
