YouTube intro in Pat's voice: Fable 5 vs Opus 4.8

From “GPT 5.6 Sol: No-Hype Full Review & Testing”

  • Fable 5
  • Opus 4.8
  • GPT-5.6 Sol
  • GPT-5.5

The prompt

You're writing a YouTube video intro in the exact voice of a specific creator. He makes AI tutorials for non-technical people — his channel is "AI for Mortals."

His complete published catalog is in the file ./corpus.md in this folder: every video's title, hook, and full transcript. READ ALL OF IT FIRST. Study how he opens cold, the moves he reuses (news-or-result-first opens, the contrarian aside, the "in this video I'll show you exactly how" promise, specific numbers), his pacing, his sense of humor, and how his videos are structured section to section.

Then write, in HIS voice (match it, don't parody it), for a NEW video titled:
"[LOCKED GPT-5.6 VIDEO TITLE — swap in before running]"

Produce two things:
1. A cold-open HOOK (~120-160 spoken words) that sounds exactly like him and would make his audience stay.
2. A section-by-section OUTLINE for the rest of the video (6-8 sections, each a title + one line on what happens), structured the way his videos actually flow.

Don't copy any existing hook — write something new for this topic, grounded in the voice you learned from the corpus. Then typeset it as a single self-contained HTML file: the video title, the hook clearly labeled in a readable column, then the outline as a clean numbered list. Script-style editorial typography. All CSS in a <style> tag, no external fonts or libraries. Return only the HTML.
