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.ComfyUI Text-to-Image Workflow Tutorial

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:

- Click the folder icon (workflows) in the sidebar
- Click the Browse example workflows button at the top of the Workflows panel

- 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:
<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.

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 
If everything goes smoothly, the model should be able to download locally. If the download fails for a long time, please try other installation methods.
<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.
