Headline type scale that steps up at the tablet and desktop breakpoints
The same task, run on 27 models. Compare the outputs side by side, or open any one in a popup to inspect it.
Top result: claude-opus-4-8 (low reasoning) at 100.0% composite. Lowest: deepseek-v4-flash at 100.0%. 27 models compared on this task.
How it ran
- Each model was given the brief below in a fresh, isolated session with no access to our tools, and returned a single self-contained index.html (inline CSS and JS, no external requests, no build step).
- The rendered output was scored 1 to 5 on brief fidelity, visual design, craft, and impact by a four-family vision panel - Anthropic (Claude Opus 4.8), OpenAI (GPT-5.5), Google (Gemini 3.1 Pro), and xAI (Grok 4.3) - using one identical prompt so the scores compare. The published judge score is leave-one-family-out: a model is never scored by a judge of its own family, so same-family self-preference is removed.
The brief
Build a single self-contained HTML file (`index.html`) that renders with no build step and no network calls (inline all CSS and JS; no external fonts, scripts, or images). Build a hero section with a single headline (an <h1> with id="headline") and a paragraph. The headline's font size must step up as the viewport widens: - on a phone (around 360px wide) the headline is a compact size, about 28px, - on a tablet (around 768px wide) it is larger, about 40px, and - on a desktop (around 1440px wide) it is a display size, about 64px. Keep the page from scrolling horizontally at any of 360px, 768px, or 1440px wide: the headline must wrap or shrink rather than run off the side of a phone. Use plain, accessible markup.
