Flash fiction prompt — 10feb26

I am sharing flash fiction prompts generated by AI for my own use unless I don’t think they are worth pursuing. Readers are welcome to try their hand at writing based on the prompts generated for this exercise.

Notes about modifications made to the AI instructions or this post template are at the end of this post if you are curious about such things.

Feel free to skip these posts if you feel you are not the target audience. If you choose not to participate, there is no need to let us know about your preferences and opinions about these prompts, or the use of artificial intelligence to generate writing prompts.

Today’s prompt:

Genre: Speculative fiction

Subgenre: Biopunk / Post-Apocalyptic

Target Length: < 2,000 words

Key Elements:

• A genetically modified plant that blooms only in moonlight.
• A rusted key that opens nothing in the protagonist’s possession.
• The sound of running water where there should be none.
• A faded photograph of a skyline that no longer exists.

If you join in, try to keep to the genre (even if it is unfamiliar) and feel free to modify the prompt elements to better suit your story while striving to keep in the spirit of the suggestions.

There is no deadline for sharing your answer to the challenge should you choose to pursue these prompts. I don’t expect anyone else to make my personal goals their own. You are not constrained to writing only prose.

If you post something on your own site, let me know in the comments below. I recommend providing a link over posting in-comment. While I appreciate any backlinks, it is not a requirement for jumping in.

Most importantly: Have fun with this.

Caveat: This doesn’t really need to be mentioned for most of you but any links within the comments MUST be an entry for this challenge; all comments will be “sanitized” of any links redirecting traffic for other purposes or deleted wholesale as “spam”. I will check to make sure it is related to the prompt shortly after a comment goes live.

Change Notes:

[10feb26] Gemini already started to iterate previous conversations and prompts to try and “please me” in less than a week since I first gave it instructions. I have reframed the scheduled prompt instructions with the intention of eliminating iteration of my previous conversations with the chat AI to hopefully provide more randomness to the prompts. Additionally, this post’s template was modified to simplify language and tighten up the content.
