Completing a Text-to-Image Workflow in ComfyUI

Fictitiousness·Nov 2025

Demo summary

The video shows the step-by-step connection of CLIP Text Encode nodes for prompts, Empty Latent Image for resolution, VAE Decode, and the Save Image node to complete a functional pipeline.

Step-by-step

Drag a connection link from the positive input of the K Sampler to a CLIP Text Encode node.
Copy and paste the CLIP Text Encode node and connect the duplicate to the negative input of the K Sampler.
Connect the CLIP output from the Load Checkpoint node to the CLIP input on both text encode nodes.
Drag out the Latent input from the K Sampler and select the Empty Latent Image node.
Set the image resolution in the Empty Latent Image node.
Drag a connection from the VAE output of the Load Checkpoint node and select the VAE Decode node.
Connect the Latent output of the K Sampler to the samples input of the VAE Decode node.
Drag a link from the VAE Decode image output and select the Save Image node.

Options

Experiment with different image sizes in the Empty Latent Image node
Set a custom file name and subfolder in the Save Image node

Watch out for

Images much larger than 1 megapixel (e.g., significantly over 1024x1024) will start to produce artifacts
Older Stable Diffusion models (pre-XL) may produce blurry details or artifacts if set higher than 512x512

Tips

Use 1024x1024 as the standard size for clean, detailed generations when using SDXL
Organize generations by using the subfolder setting in the Save Image node
Note that in SDXL, the VAE is baked into the model checkpoint, so you don't need a separate loader node
