ComfyUI UX Combinatorial

A dependency-free ComfyUI custom node that expands combinatorial prompt syntax.

CombinatorialPromptBatch accepts positive_prompt and batch_size and returns:

• prompts: every ordered combination produced by {a|b} groups.
• effective_batch_size: 1 for a dynamic prompt, or the selected batch size for a regular prompt.
• combination_count: the number of generated combinations.

Nested groups, empty alternatives, and escaping of \{, \}, \|, and \\ are supported. Expansion is capped at 32 combinations.

Examples

| Prompt | Output | | --- | --- | | portrait | portrait | | girl with {red|blue} dress | Two prompts | | {red|blue} {dress|shirt|coat} | Six prompts | | {red|{blue|green}} ball | Three prompts |
