2. Writing Quality

Creative Writing Test

Prompt: “Write an opening paragraph for a mystery novel”

ChatGPT Response:

The rain hammered against the windows of 221B Baker Street like a thousand tiny fists demanding entry. Detective Sarah Chen stared at the photograph in her hands—a smiling family that no longer existed. Three weeks ago, they had vanished without a trace, leaving behind only this image and a cryptic note that read: “Look where shadows forget to fall.”

Claude Response:

Eleanor’s hands trembled as she unsealed the envelope, its edges yellowed with age and secrets. Forty years her mother had kept this hidden, and now, three days after the funeral, Eleanor understood why. The photograph inside showed a man she’d never seen—yet whose eyes were unmistakably her own. On the back, in her mother’s careful handwriting: “Your father. Forgive me.” But it wasn’t the revelation that made Eleanor’s blood run cold. It was the newspaper clipping tucked behind it, dated 1962, with the headline: “Local Man Found Dead in Mysterious Circumstances.”

Gemini Response:

The lighthouse had been dark for seventeen years when the light appeared again. Not the steady beam of old, but a flickering, irregular pulse that seemed to spell out a message in a code long forgotten. Marine biologist Dr. James Whitmore noticed it first, dismissing it as a malfunction—until he recognized the pattern. It was Morse code. And it was spelling his name.
