About Text-to-Image

Text-to-Image is a fundamental AI drawing feature that generates images from text descriptions. It’s one of the most commonly used functions in AI art generation. You can think of the process as telling your requirements (positive and negative prompts) to an artist (the drawing model), who will then create what you want. Detailed explanations about text-to-image will be covered in the Text to Image chapter.

2. Load Default Text-to-Image Workflow

ComfyUI usually loads the default text-to-image workflow automatically when launched. However, you can try different methods to load workflows to familiarize yourself with ComfyUI’s basic operations:
ComfyUI InterfaceFollow the numbered steps in the image:
  1. Click the Fit View button in the bottom right to ensure any loaded workflow isn’t hidden
  2. Click the folder icon (workflows) in the sidebar
  3. Click the Browse example workflows button at the top of the Workflows panel
Continue with:Load Workflow
  1. Select the first default workflow Image Generation to load it

​
3. Model Installation

Most ComfyUI installations don’t include base models by default. After loading the workflow, if you don’t have the v1-5-pruned-emaonly-fp16.safetensors model installed, you’ll see this prompt: First, ComfyUI will warn you that some models are missing: Missing models warning Click the warning to see which model is missing and the download link: Missing model details All models are stored in <your ComfyUI installation>/ComfyUI/models/ with subfolders like checkpoints, embeddings, vae, lora, upscale_model, etc. ComfyUI detects models in these folders and paths configured in extra_model_paths.yaml at startup.
Desktop models folder pathOn ComfyUI Desktop, the models folder location may differ from portable/other installs. Follow these steps:
  1. Click the logo at the top-left
  2. Open Help → Open folder
  3. Choose Open models folder
If your interface is in another language, the exact menu text may differ, but the flow is the same: Help → Open folder → Open models folder (or the closest equivalent in your language).
You can install models through:
After you click the Download button, ComfyUI will execute the download, and different behaviors will be performed depending on the version you are using.
The desktop version will automatically complete the model download and save it to the <your ComfyUI installation location>/ComfyUI/models/checkpoints directory. You can wait for the installation to complete or view the installation progress in the model panel on the sidebar.Model Download Progress
Automatic downloads typically fetch models from Hugging Face. Make sure your network can reliably reach Hugging Face.If the download does not start or shows no progress for a long time, copy the model link from the missing-model details (or use the manual installation section below) and install the model manually.

4. Load Model and Generate Your First Image

After you install or update models, press R on your keyboard to refresh object definitions and update model lists in nodes (for example, the dropdown in Load Checkpoint). Then continue with the steps below: Run workflow
  1. In the Load Checkpoint node, ensure v1-5-pruned-emaonly-fp16.safetensors is selected
  2. Click Run or press Ctrl + Enter to generate
