I tested every thinking level in the new ChatGPT (GPT-5.6 "Sol") on one thing only: fiction. Same prompt, word for word, at every level. Then I scored every output with my Prose Analyzer, which counts what editors actually count. I hope you enjoy this ChatGPT 5.6 test.

The test: the opening 500 words of a literary suspense novel. A woman returns home for a funeral and realizes someone has been living in her childhood bedroom. Every level got the identical prompt. Every output went through the same analyzer. The scores and the podium are all in the video.

Quick clarification for the detail-minded: "Pro" is a thinking level in the picker; the $200 refers to the ChatGPT Pro plan, which is the only plan that unlocks that level. Also, I kept calling the "high" and "extra high" levels "hard" and "extra hard" for some reason. I fixed it in a few places but if you notice the different words, they mean the same thinking level.
