27 Public Endpoint Nodes - Ready-to-use nodes for RunPod's public AI models
Custom Serverless Nodes - Connect to your own RunPod workers
Image/Video/Audio Support - Generate images, videos, and audio
Async Job Handling - Automatic polling with status updates

Usage

Public Endpoints

Add any public endpoint node (e.g., "Flux Dev") to your workflow
Enter your RunPod API key
Configure the parameters (prompt, size, etc.)
Connect to a Preview Image or Save Image node

Example - Flux Dev:

[Flux Dev] → [Preview Image]
     ↑
 api_key: "your-runpod-api-key"
 prompt: "A serene mountain landscape at sunset"
 width: 1024
 height: 1024

Image Editing Nodes

Nodes like Flux Kontext Dev, Qwen Image Edit, Seedream 4.0 Edit, and Nano Banana Edit accept optional image inputs:

Single image input: Connect an IMAGE to input_image
Multiple images (Nano Banana, Seedream Edit): Connect to input_image_1 and input_image_2

Video Nodes

Video nodes return a URL string. Use a "Load Video from URL" node or download the video:

[WAN 2.5] → [Save Text] or custom video loader
     ↑
 video_url output → "https://..."

⚠️ Video/audio URLs expire after 7 days. Download immediately if you need to keep them.

Custom Serverless Workers

For your own RunPod workers:

Deploy a serverless endpoint on RunPod
Use the appropriate node (SDXL, SD, or ComfyUI Workflow Runner)
Enter your endpoint ID and API key

ComfyUI Workflow Runner:

Export your workflow: Workflow > Export (API)
Paste the JSON into workflow_json
Optionally connect an input image
The node sends the workflow to your worker-comfyui endpoint

API Key

All nodes require a RunPod API key. You can:

Enter it directly in each node
Create a reusable "Primitive" node with your API key

Get your API key at: https://www.runpod.io/console/user/settings

Pricing

Public endpoints are billed per use. See RunPod's pricing for current rates:

Image generation: ~$0.02-0.03 per megapixel
Video generation: ~$0.30-1.20 per video
Audio: ~$0.05 per 1000 characters

Troubleshooting

Node appears to "hang"

Public endpoints can take 30-120 seconds depending on server load

Check the ComfyUI console for status updates:

[RunPod] Submitting job to black-forest-labs-flux-1-dev...
[RunPod] Job submitted: abc123
[RunPod] Status: IN_QUEUE (elapsed: 0s)
[RunPod] Status: IN_PROGRESS (elapsed: 15s)
[RunPod] Job completed successfully

"Job failed" errors

Verify your API key is valid
Check you have sufficient credits
Some endpoints require specific image formats or sizes

Large images fail

RunPod has request size limits (10MB for async, 20MB for sync)
Use smaller images or URL inputs instead of base64
