4.1 Overview of the Editor Interface
The canvas is a visual editor where you build workflows by placing and connecting nodes.4.2 Node Library
GMI Official Nodes
GMI Official nodes are fully managed API-backed nodes covering four generation modalities: Image, Video, Audio, and LLM. Additional utility nodes include GMI Image Upload and Batch Images. Each node accepts a specific input type (text, image, video, or audio) and produces a corresponding output. Nodes are sourced from our partner ecosystem and are updated regularly as new models become available.4.2.1 Video Nodes
Video nodes generate or transform video content. They fall into three input categories:| 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 |
4.2.2 Image Nodes
Image nodes generate or edit images. They fall into three input categories:| Input Type | What it does | Example Models |
|---|---|---|
| Text → Image | Generates an image from a text prompt | Google (Gemini), Seedream, Tongyi (Alibaba), Reve, Bria |
| Image → Image | Edits or transforms an existing image | SeedEdit, Reve, Bria |
| Image + Mask → Image | Fills or replaces a selected region | Bria |
4.2.3 Audio Nodes
Audio nodes generate speech or clone voices from text and audio inputs. Note: Only WAV and MP3 file formats are supported for audio uploads.| 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 |
ComfyUI Nodes
Native ComfyUI nodes sourced directly from the official ComfyUI repository. These include standard preprocessing, conditioning, and utility nodes commonly used in ComfyUI workflows.When to Use GMI Official Nodes 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 |
4.3 Canvas Basics
- Add Node: Right-click → Add Node, or search in the node library panel
- Delete Node: Select the node and click the trash icon
- Drag & Arrange: Move nodes freely on the canvas
- Connect Nodes: Drag from the output of one node to the input of another — data types must match for the connection to be valid
4.4 Toolbar Functions
- Run: Execute the workflow
- Save: Save workflow changes
