How this task was evaluated
Results are ordered by this task's published score. API runs use one prompt and one completion; agent runs use a coding harness with tools and iteration. Inspect the execution method when comparing results.
Objective scores use the benchmark's execution checks. Judge scores use a vision panel's fixed rubric; the published score leaves out a model's own family. Missing values are labelled rather than treated as zero.
Read the brief
Build a self-contained FAQ accordion as a single HTML file (`index.html`) that renders with no build step and no network calls (inline all CSS and JS). Requirements: - at least three FAQ items, each with a question header and an answer panel, - each header is a real button exposing accessible state with aria-expanded, starting collapsed (aria-expanded="false") with its panel hidden, - clicking a header expands that item: its aria-expanded flips to "true" and its answer panel becomes visible; clicking again collapses it. Use plain, readable, accessible markup. No external fonts or scripts.
