Original prompt
Write me a short story about a lighthouse keeper.
Optimized prompt
Write the piece to this brief. Start in the middle of a scene — no preamble, no scene-setting paragraph. Form: [short story / flash fiction / scene / poem], target [N] words. POV & tense: [e.g. first person, past] Tone: [e.g. quiet, wry, unsettling] Subject / situation: [one or two lines] Hard constraint: [one thing that must be true — a line that must appear, a word that must not, an ending that must land a certain way] Deliver only the piece. No title unless I asked, no author's note, no explanation of your choices.
Why this GPT-4o prompt works
Tuned for GPT-4o: a crisp brief — form, POV, tone, length, one hard constraint — and an instruction to open mid-scene. GPT-4o writes cleanly to a tight spec and tends to add a warm-up paragraph unless told plainly not to.
What to check in the output
- The 'vibe_prompt' is very open-ended and could lead to a wide variety of story qualities.
