Statement
Last reviewed: October 6, 2026.
Our target
We aim for this website to meet the Web Content Accessibility Guidelines (WCAG) 2.2 at level AA. That is the standard we build and test against; it is a target, not a claim that every page already conforms.
How the site is built
- Structure. Pages use semantic HTML: a single main heading per page, landmarks for the header, navigation, main content, and footer, and a skip link to the main content.
- Keyboard. Links, the menu, tabs, filters, and forms work without a mouse. Escape closes the menu, and the arrow keys move between tabs. The charts on the frontier models pages take focus, and the arrow keys step through their models.
- Visible focus. Links, buttons, and form fields show a heavy focus outline, recolored so it stays visible on blue, orange, and cream sections.
- Reduced motion. When your device asks for less motion, the homepage’s scroll-driven opening stays still, the moving text bands and the spinning shapes in the footer stop, and smooth scrolling and transitions are switched off.
- Text and layout. Headlines and copy are real text, not pictures of text. Layouts reflow down to 320 pixels wide, and on a phone the model directory and the explorer’s grid restack as cards.
- Images and charts. Decorative art is hidden from screen readers. Each chart carries a text summary, and the Artificial Analysis logo carries its name.
- Forms. Every field has a visible label. Errors are written out next to the field and announced to screen readers, and focus moves to the first field that needs attention.
- Fonts and scripts. Fonts, images, and our analytics script are served from our own domain, and the site loads no third-party scripts.
How we test
Every build runs automated checks: a single main heading on each page, every internal link and anchor resolves, structured data parses, and no third-party fonts or assets load. We review pages in a browser at widths from a small phone to a wide desktop.
Known limitations
- The charts on the frontier models page are drawn graphics. Tab to a chart and step through it with the arrow keys, and each model is read out with its lab, release date, and score. The tables that go with the charts list only the releases that raised the top score and the models on the price and speed frontiers, not every model plotted.
- Every model’s figures are in the model explorer’s sortable grid. Without JavaScript, the grid lists only the highest-scoring models, and the map and the match score do not appear.
- The model explorer is a large page with a long table, and can be slow on older devices.
- Links to other sites, such as LinkedIn and Artificial Analysis, lead to pages we do not control.
