Workflow Canvas

The canvas is a ComfyUI-based visual editor. Workflows are graphs of nodes wired together by their input / output sockets.

Editor surface

The editor has six concurrent surfaces.

Surface	Where	Purpose
Top bar	Above canvas	Workflow name, save status, save, Run
Inner side toolbar	Strip at the canvas left edge	Six icons: Library, Assets, Toolbox, Comfy Library, Undo, Redo
Left palette	Flips out from the inner toolbar	Browse and place nodes (Model Library, Assets, Toolbox, Comfy Library)
Canvas	Center	Nodes, wires, group boxes
Right inspector	Slides in when a node or the canvas is clicked	Per-node Parameters / Info / Settings, or the Workflow Overview
Bottom-right controls	Below canvas	Cursor mode, zoom %, fit-to-view, minimap, hide-overlays

A stats panel at bottom-left shows T (run time), I (iteration), N (nodes / selected), V (views), and FPS. Six icons stacked vertically against the canvas:

Library, the Model Library palette (Audio / Image / Video / LLM / Task).
Assets, the Assets palette (Save / Load Image, Save Audio (FLAC / MP3 / Opus), Load 3D & Animation, Preview 3D & Animation).
Toolbox, image / LLM / video tools plus Comfy Library entries.
Comfy Library, the full Comfy node tree (Audio, latent, image, …).
Undo (Cmd+Z).
Redo (Cmd+Shift+Z).

Click an active icon again to collapse the palette.

Model Library

The default palette has five category tabs.

Audio

Text-to-speech models. Cards include ElevenLabs TTS V3 / V2, Inworld 1.5 Mini / Max TTS, and more. Each card shows the provider, short description, and per-request price.

Input Type	What it does	Example Models
Text → Audio	Converts text to natural-sounding speech	Inworld, MiniMax, ElevenLabs
Text + Voice Sample → Audio	Clones a voice and speaks the given text	Inworld, MiniMax, Step Audio

Only WAV and MP3 file formats are supported for audio uploads.

Image

Categories: Image Editing, Text-to-Image. Models include Bria Fibo, ByteDance Seedream 3 / 4 / 5, Google Gemini image, GPT-Image-2, Hunyuan, Luma Uni, Reve, and more.

Input Type	What it does	Example Models
Text → Image	Generates an image from a prompt	Gemini, Seedream, Tongyi (Alibaba), Reve, BRIA
Image → Image	Edits or transforms an image	SeedEdit, Reve, BRIA
Image + Mask → Image	Fills or replaces a selected region	BRIA

Video

Categories cover Text-to-Video, Image-to-Video, Video-to-Video, Audio-to-Video. Providers: Veo3, Sora-2 / 2-Pro, Kling, Aliyun Wan, BytePlus Seedance, PixVerse, MiniMax Hailuo, LTX-2, Vidu, Luma Ray, SkyReels, HeyGen, GMI workflow models, Bria video tools.

Input Type	What it does	Example Models
Text → Video	Generates a video from a text prompt	Wan, Veo, Sora, Kling, MiniMax Hailuo, PixVerse, Seedance, Luma
Image → Video	Animates a still image into a video	Wan, Kling
Video → Video	Edits or transforms an existing video	Wan, Kling, BRIA

LLM

All inference-side language models, grouped by category. This is the same catalog you see on the Inference Model Hub.

Task

Task-specific image operations such as Bria Eraser, Bria Genfill, Bria Fibo Edit, Bria Fibo Restyle, Bria Fibo Recolor. Click any model card to place that node at the canvas cursor. For the universal search across every catalog, see Library, Search & Blueprints.

Assets palette

Holds the I/O building blocks: Save Image, Load Image, Save Audio variants (FLAC / MP3 / Opus), Load 3D & Animation, Preview 3D & Animation, and document loaders.

GMI Official vs ComfyUI nodes

	GMI Official Nodes	ComfyUI Nodes
Best for	Quick setup, managed inference	Fine-grained control, custom logic
Control level	Simplified inputs / outputs	Full node-level customization
Performance	Optimized, fully managed	Depends on workflow configuration

GMI Official nodes wrap each model behind a clean input / output surface and run on managed infrastructure. ComfyUI nodes are sourced directly from the upstream Comfy repo for users who need lower-level building blocks.

Right inspector, per node

Click a node and the right inspector opens with three tabs.

Parameters

Every input the node exposes. For an LLM node: model, prompt, temperature, max_tokens, system prompt, image_url, video_url. Each row has a ⋮ menu to favorite the input (it then shows up at Workflow Overview > Parameters).

Info

Node header, identifier, and (when present) a description of what the node does. Some nodes show pricing here.

Settings

Node state: Normal, Bypass, Mute.
Node color: 10 preset swatches.
Pinned: toggle.

Clicking a node header pops a contextual toolbar above it.

Icon	Action
🗑️	Delete node
ⓘ	Toggle Info / open Inspector
🟡 ▾	Node color picker
⤓	Collapse / Resize
↪	Bypass
▶	Run Branch (run just this node and upstream)
⋮	More menu (see below)

Per-node actions: Rename, Copy Ctrl+C, Duplicate Ctrl+D, Clone, Run Branch, Pin, Bypass Ctrl+B, Convert to Subgraph, Minimize Node, Collapse, Resize, Node Info, Color, Shape, Extensions. Right-clicking a widget input (e.g. image_url) exposes widget-level actions:

Highlights: Favorite Widget (pin to Workflow Overview > Parameters), Rename Widget, Convert to Subgraph, Convert Widget to Input (so it accepts a wired connection instead of inline editing).

Workflow Overview

Click the canvas background with no node selected and the inspector switches to Workflow Overview with three tabs.

Parameters

Lists every input you’ve favorited from individual node Parameters. This is the workflow’s parameter surface, what a consumer of the workflow (or someone running it via API) actually has to fill in. Empty state: “NO FAVORITED INPUTS. Inputs you favorite will show up here. In the Parameters tab, click ⋮ on any input to add it here.”

Nodes

Flat list of every node in the workflow. Each row has quick actions: reset, target (center camera on node), expand details.

Global Settings

NODES: Show advanced parameters, Show toolbox on selection, Nodes 2.0.
CANVAS: Grid spacing (default 10), Snap nodes to grid.
CONNECTION LINKS: Link shape, Show connected links.
View all settings opens the full app settings.

Wiring nodes

Each node exposes:

Output sockets on the right edge, coloured dots labelled by their data type (IMAGE, MASK, LATENT, STRING, content, …).
Input sockets or widgets on the left edge, either small dots for raw inputs, or full-width widget bars (image_url, video_url, model, prompt) that double as both editable widget and connection point.

To wire two nodes, drag from an output socket to a compatible input socket. The cursor shows a coloured curve as you drag, and only matching types accept the drop.

A widget input shows its tooltip on hover:

If you want a widget to behave purely as a linked input (no inline editing), right-click and pick Convert Widget to Input. Right-click on empty canvas to add nodes, groups, paste, or save selections as templates.

Add Node (submenu of every node category)
Add Group
Paste
Manage Group Nodes
Add Group For Selected Nodes
Save Selected as Template (becomes a Blueprint, see Library, Search & Blueprints)
Node Templates

Top bar

Workflow name, click the breadcrumb to rename.
Saved a few seconds ago live save indicator (auto-save fires on every change).
save, force-save now.
Run, execute the entire workflow.

Saving never overwrites a published workflow without confirmation. Runs spend credits according to the model nodes in the graph.

Bottom-right controls

Cursor mode: selection vs pan.
Fit-to-view (crosshair): re-frames the canvas around every node.
Zoom %: preset zoom levels.
Minimap toggle: show or hide the floating minimap.
Hide overlays: temporarily clear UI overlays for a clean canvas.
