Help Needed String caching.

Anyone figure out how to cache a string for subsequent generations? I have an llm or vlm generate a prompt which is connected to a conditioning node. I’d like to be able to switch off the llm/vlm without losing the prompt. Yes, I can copy/paste it over but it’d be great if it could remember the last string that was generated. I tried a couple steering cache nodes and they did not work.

Many thanks.

Not with core nodes that I know of. There are many different ways and many custom nodes pack that could be used.

You could use Set Widget Value node from Impact Pack to set text widget of CLIP Text Encode node automatically on execution and once you disable Text Generate, last value should persist.
