Visual Prompt Engineering

Research project on how visual prompts can improve creative story writing and iteration.

Highlights

  • Compared prompt iterations
  • Evaluated stories across multiple dimensions
  • Turned research into a paper/poster-style project

Overview

Independent research (Jun–Nov 2024) on whether visual prompts can improve creative story writing and how stories change across prompt iterations — published as two peer-reviewed papers in 2025.

Method

I designed experiments combining LLMs with diffusion models to accelerate creative writing workflows. Stories generated under different prompt conditions were evaluated with a rubric across multiple dimensions, with human graders scoring the outputs.

Findings

The prompt-engineering techniques improved model iteration efficiency by 39–51%. Full methodology and results are in the papers linked above.
