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 0.0%. 27 models compared on this task.
Build a single self-contained page as one HTML file (`index.html`) that renders with no build step and no network calls (inline all CSS and JS, no external fonts or scripts). Build an accordion FAQ following the WAI-ARIA accordion pattern. Requirements: - At least three accordion items. Each header is a real <button> with the ids acc-shipping, acc-returns, acc-billing, each carrying aria-expanded (all "false" on load) and aria-controls pointing at its panel. - Each panel (ids panel-shipping, panel-returns, panel-billing) starts hidden. Activating a header button with Enter or Space flips its aria-expanded to "true" and reveals its panel; activating again collapses it. - When a header button has focus, ArrowDown moves focus to the next header and ArrowUp to the previous (wrapping at the ends). The accordion must be fully operable with the keyboard alone. Use plain, accessible markup.
