Conditioning nodes convert text prompts into embeddings and manipulate how they guide the image generation process.

​
Text Encoding

CLIPTextEncode

Encodes a text prompt using a CLIP model into an embedding that guides the diffusion model. Category: conditioning
​
string
required
The text prompt to encode. Supports multiline and dynamic prompts.
​
CLIP
required
The CLIP model used for encoding the text
Returns:
  • CONDITIONING: The encoded text embedding used to guide the diffusion model
Description: Encodes a text prompt using a CLIP model into an embedding that can be used to guide the diffusion model towards generating specific images. This is the primary way to create positive and negative prompts.
