Poem prompts from one image (everyday)

Give me 5 original writing prompts on this theme, numbered, each one to three sentences with something at stake. Make them poem prompts: an image or a moment to write a poem from.

The sea in winter.

Sent with the Writing prompt generator's own instructions as the system prompt, as a free run of the tool sends them.

Graded on:

  • Five angles: The five prompts approach the winter sea in clearly different ways (different speakers, moments or images), not one idea reworded.
  • Concrete: Each prompt offers a concrete image or moment to write a poem from, not an abstract theme.
  • Room to write: Each prompt is one to three sentences and leaves the poem to the writer.

How the Writing prompt generator's test inputs are scored, with every model's results on all five.
