ComfyUI - Dynamic Prompts

Collection of custom nodes for ComfyUI implement functionality similar to the Dynamic Prompts extension for A1111.

The nodes use the Dynamic Prompts Python module to generate prompts the same way, and unlike the semi-official dynamic prompts nodes, the ones in this repo are a little easier to utilize and allow the automatic generation of all possible combinations without manual queuing.

Install

Option 1

Install via ComfyUI-Manager.

Option 2

Clone the repository into your ComfyUI custom_nodes directory and install the requirements in your ComfyUI Python environment.

git clone https://github.com/exectails/comfyui-et_dynamicprompts
cd comfyui-et_dynamicprompts
pip install -r requirements.txt

Nodes

Dynamic Prompt

Generates prompts and seeds based on text input. The node will either generate a given number of prompts, choosing randomly from all possible combinations, or return prompts for all possible combinations.

Random Prompts

The random mode generates a number of prompts, each one using randomly chosen variations from all potential combinations.

Example 1

Output one prompt with three possibilities.

Input

count: 1
text: "a {red|blue|green} dog"

Output

["a red dog"]

Example 2

Output two prompts with three possibilities.

Input

count: 2
text: "a {red|blue|green} dog"

Output

["a green dog", "a red dog"]

Example 3

Output one prompt with six possibilities.

Input

count: 1
text: "a {red|blue|green} dog and a {pink|yellow} cat"

Output

["a blue dog and a yellow cat"]

Combinatorial Prompts

In this mode the node generates and returns a list of prompts that make up every single possible combination of strings based on the input text.

Example 1

Output three prompts based on three possibilities.

Input

"a {red|blue|green} dog"

Output

["a red dog", "a blue dog", "a green dog"]

Example 2

Output six prompts based on six possibilities.

Input

"a {red|blue|green} dog and a {pink|yellow} cat"

Output

[
    "a red dog and a pink cat",
    "a red dog and a yellow cat",
    "a blue dog and a pink cat",
    "a blue dog and a yellow cat",
    "a green dog and a pink cat",
    "a green dog and a yellow cat",
]

Seeds

To give a degree of control over the seeds used in the generation to the dynamic prompt, you may plug the result into the sampler's seeds input. The seed will then be fixed, sequential, or random.

Fixing the seed is useful if you'd like to generate an image with a certain subject but slight variations in colors or other details. In this mode each prompt will receive the seed set on the node.

Sequential seeds start at the given seed for the first prompt and increase by one for every subsequent one. This can be used to get a degree of determinism, but without giving all prompts the same seed.

Finally, random seeds are determined by the given seed, but are randomly generated otherwise. It's very similar to sequential, but less deterministic from the outside.
