ComfyUI Setup Guide for AI Image Generation

ComfyUI has revolutionized how creators build AI art workflows — and with Promptus CosyFlows, it’s easier than ever to install, automate, and scale your image generation.

Whether you’re just starting with AI image generation or moving beyond local setups, this guide will help you install ComfyUI, connect it with CosyFlows, and start creating stunning visuals effortlessly.


💾 Download and Install ComfyUI

Start by downloading Promptus with ComfyUI

🔗 ComfyUI on Promptus

💡 CosyFlows Tip: Promptus automatically detects your GPU setup and lets you run ComfyUI workflows locally or on the cloud — no manual switching required.


💡 CosyFlows Integration: Once models are linked, you can sync them to Promptus and reuse them across workflows — saving time and space.


🧩 Exploring the Node Interface

ComfyUI’s visual workflow is at the heart of CosyFlows.
Each node represents a step in your image generation process:

  • 🧱 Load Checkpoint — choose your AI model
  • 🗒️ CLIP Text Encode — process your prompt
  • 🔄 KSampler — generate the image
  • 🖼️ VAE Decode — turn data into pixels

🧠 With CosyFlows, these nodes can be saved, shared, and reused inside Promptus’ team workspace, so creators can collaborate or remix workflows instantly.


⚙️ Tuning Your Generation Settings

In the KSampler node, adjust how your images are created:

  • 🎲 Seed: Fix or randomize your output.
  • 🧮 Steps: More steps = sharper quality, slower results.
  • 🎯 CFG Scale: Controls prompt strength (best range: 4–7).
  • 🧪 Sampler: Use DPM++ 2M Karras for reliable results with Stable Diffusion 1.5/2.0.

💡 CosyFlows Advantage: Save your generation settings once and apply them to any model instantly — perfect for batch image generation or team templates.


🔗 Working with Shared Workflows

One of ComfyUI’s best features is workflow sharing — and CosyFlows supercharges it.
When someone shares a workflow or image, you can:

  1. Drag it directly into ComfyUI or import it into Promptus.
  2. CosyFlows automatically detects missing nodes and installs them for you.

No more manual setup. CosyFlows syncs dependencies and keeps all your workflows cloud-ready.


🧩 Installing Custom Nodes and Extensions

Want to extend ComfyUI?

Install the ComfyUI Manager for easy custom node management:

  1. Download from GitHub.
  2. Place it in ComfyUI/custom_nodes.
  3. Restart ComfyUI.

In Promptus CosyFlows, this process is simplified — you can browse, install, and update custom nodes right from the web dashboard.

💡 Example: Need a new upscaler or LoRA loader? CosyFlows installs it with one click, then syncs it across your team’s workspace.


Advanced Workflow Examples

Inside ComfyUI’s GitHub (and within Promptus’ workflow library), you’ll find powerful templates like:

  • 🎭 Inpainting: Edit image regions with masks.
  • 🧬 LoRA workflows: Add style layers or model adapters.
  • 🧱 Multi-stage pipelines: Combine models for cinematic results.

📦 In CosyFlows, you can remix these directly — drag, modify, and save them as reusable workflow components.


🖼️ Generate Your First AI Image

You’re ready to create! 🚀

  1. Load a base workflow (or import from CosyFlows).
  2. Pick your model.
  3. Add your positive and negative prompts.
  4. Set resolution (start with 512x512).
  5. Click “Queue Prompt” — and watch the nodes light up! 🌈

Once complete, your image will appear in the Save Image node — and automatically sync to your Promptus gallery if connected.


🏁 Conclusion

With ComfyUI + Promptus CosyFlows, you get the best of both worlds:

  • Local power with your GPU
  • Cloud scalability with zero setup
  • Team sharing and one-click automation

Whether you’re an AI hobbyist or a creative professional, CosyFlows turns ComfyUI into a streamlined, collaborative AI studio.

Frequently Asked Questions

ComfyUI runs on Windows, macOS, and Linux. For basic workflows, 8 GB VRAM is usually enough; for advanced tasks (LoRAs, upscaling, batching), 16 GB+ VRAM is recommended. If your system is underpowered, Promptus CosyFlows can offload workflows to cloud GPUs so you’re not blocked by local hardware.

Yes. You can link your existing models locally to ComfyUI, or upload them once to Promptus and reuse them across workflows. This avoids duplicate downloads and helps keep results consistent across devices and teams.

Red errors usually mean a workflow is missing custom nodes or dependencies. With Promptus CosyFlows, missing nodes can be detected and installed through the cloud manager, keeping dependencies synced and reducing broken workflow issues.

Not necessarily. Instead of manually downloading repositories, placing folders into ComfyUI/custom_nodes, and restarting, Promptus CosyFlows can simplify node management by letting you browse, install, and update custom nodes from a web dashboard and sync them across your workspace.

ComfyUI is more powerful but can feel more technical at first because it’s node-based. Automatic1111 is simpler and UI-driven. Promptus CosyFlows helps bridge the gap by providing reusable workflows, easier dependency handling, and shared templates so beginners can start fast while power users scale up.

They serve different goals. For advanced workflows, ComfyUI + CosyFlows excels at modular pipelines, complex multi-stage graphs (inpainting, LoRAs, multi-model), team collaboration, cloud + local hybrid execution, and automation for batch production—making it a strong choice for studios and power users.

Yes. Workflow sharing is a major strength of ComfyUI, and CosyFlows makes it smoother by helping with imports, dependency syncing, and faster collaboration. Teams can share, remix, and reuse workflow components without repeating setup steps.

Beginners who want powerful workflows without setup pain, intermediate users moving beyond local-only limits, and power users or studios that need collaboration, automation, and cloud GPUs. If you’re hitting the limits of traditional Stable Diffusion UIs, this stack is designed to scale with you.
