Random Multiprompt Picker

The sibling of the Endless Random_Prompt_Selector, this one doesn't pick a single line - it picks several. Random_Prompt_Multipicker takes your line-per-prompt list, pulls num_to_pick of them, and joins the picks into one output string. Tired of rolling one prompt at a time when you want to generate a whole batch of variations? This is the node that feeds a multi-prompt batch from a pool.

Inputs and outputs

• prompts - multiline list, one prompt per line.
• num_to_pick - how many to select, 1 to 100, default 2.
• allow_duplicates - if off (default), picks are unique via random.sample; if on, random.choices lets the same prompt appear multiple times. This matters more than it looks: with duplicates off and num_to_pick larger than your list, the node silently caps at the list length.
• delimiter - how the picked prompts are joined, default \n (newline). Change it if you're feeding something that expects commas or pipes.
• seed - the reproducibility knob, 0 to 4294967295. Same seed, same picks.

Output: selected_prompts - one STRING, the picks joined by delimiter.

How it works and where it fits

Same deterministic core as the single-picker: random.seed(seed), then a sample. The output string is designed to flow straight into the Endless batch prompt nodes - feed it to SimpleBatchPrompts or FluxBatchPrompts and each selected prompt becomes an image in the batch. That's the killer combo: a prompt pool, a seed, and one render pass producing several different subjects.

Set delimiter to \n for the batch nodes (they split on newlines). If you're building a prompt string for a single image instead, a space or comma delimiter gives you a combined prompt.

Gotchas

Watch num_to_pick vs. your list length when duplicates are off - picks get capped, and you may think you're getting 10 variations when the pool only has 6. And the standing pack caveat: single hobbyist maintainer, AI-assisted, mid-2025 rewrite. The logic is a few lines of Python, so this is about as safe as custom nodes get.
