A1111 Prompt Node (God Node)

A custom ComfyUI node that implements A1111-style prompt handling with proper isolation and emphasis math.

Installation

Requires lark for full nested syntax support:

pip install lark

✅ Working Features

Core Features

• Hard Chunking (The Sandbox): Tokens split into 75-token chunks with padding, preventing concept bleeding
• Direct Scaling (Anti-Burn): Uses z * weight instead of Comfy's interpolation, avoiding artifacts at high weights
• BREAK Support: Fully isolated context windows
• Emphasis: (text:1.2), (text), [text]

Scheduling (Fully Recursive)

Syntax	Meaning
[cat:dog:0.5]	Switch from "cat" to "dog" at 50%
[cat:dog:10]	Switch at step 10 (requires steps input)
[glasses:0.5]	Add "glasses" at 50%
[glasses:10]	Add at step 10
[hat::0.7]	Remove "hat" at 70%
[hat::15]	Remove at step 15

Nested syntax supported:

[honovy, exsys:chen bin, [as109|fkey], [sweetonedollar:11]:0.4]

Alternation

• [white|black] - Blends concepts (50/50 average)
• [A|B|C] - Equal blend of 3 options (33% each)

Model Support

• SDXL: Dual CLIP (clip_l + clip_g) with independent weight scaling
• SD1.5: Full support

Inputs

Input	Type	Description
clip	CLIP	The CLIP model
text	STRING	Prompt with A1111 syntax
steps	INT	Total sampling steps (for step-based scheduling)
normalization	BOOL	Enable EmphasisOriginalNoNorm

🚧 Known Limitations

• Token Counter: Display pending frontend integration
• True Alternation: Uses blending, not per-step switching (would need sampler hooks)
• Without Lark: Nested syntax won't parse; falls back to simple regex

Usage Examples

# Basic emphasis
a (beautiful:1.3) landscape

# BREAK for isolation
artist name BREAK character name, wearing a hat

# Step-based scheduling (with steps=28)
[mountains:ocean:14] at sunset

# Nested scheduling with alternation
1girl, [honovy:chen bin, [as109|fkey]:0.4]

# Combined
(epic:1.2) [forest:city:0.3] BREAK detailed background
