Sage_DualCLIPTextEncodeLumina2

Dual Prompt Encode (Lumina 2)

Encodes positive and negative prompts using a CLIP model with Lumina 2-specific system prompts for enhanced image-text alignment.

Inputs

Required

clip (CLIP): The CLIP model used for encoding the text
system_prompt (STRING): Lumina 2 system prompt type selection
clean (BOOLEAN): Clean up the text, getting rid of extra spaces, commas, etc. (default: False)

Optional

pos (STRING): The positive prompt's text (multiline, supports dynamic prompts)
neg (STRING): The negative prompt's text (multiline, supports dynamic prompts)

Outputs

pos_cond (CONDITIONING): Conditioning containing the embedded positive text with system prompt
neg_cond (CONDITIONING): Conditioning containing the embedded negative text with system prompt. If neg is not connected, it'll be automatically zeroed
pos_text (STRING): The positive prompt text with system prompt prefix (cleaned if clean=True)
neg_text (STRING): The negative prompt text with system prompt prefix (cleaned if clean=True)

System Prompt Options

Superior

"You are an assistant designed to generate superior images with the superior degree of image-text alignment based on textual prompts or user prompts."

Alignment

"You are an assistant designed to generate high-quality images with the highest degree of image-text alignment based on textual prompts."

Usage

Use for workflows that require Lumina 2 prompt encoding with specialized system prompts. The system prompts are automatically prepended to your prompts with <Prompt Start> delimiter.

Notes

Specifically designed for Lumina 2 model compatibility
System prompts enhance image-text alignment quality
Automatically formats prompts as: {system_prompt} <Prompt Start> {user_prompt}
More efficient than using two separate CLIP Text Encoder nodes
Automatically handles unconnected inputs by zeroing the conditioning
Text cleaning removes extra spaces, commas, and formatting issues
Supports dynamic prompts for both positive and negative inputs
Progress bar shows encoding progress for both prompts
Part of "Sage Utils/clip" category for conditioning operations
