Openai
openai.comThe reference for white-canvas restraint: a pure #ffffff page where black #000000 type and a single ChatGPT-style 9999px pill input do all the work, and colour is rationed to editorial imagery alone.

Reference it for
- Empty-canvas hero: no illustration, no gradient, a centred question ("What can I help with?") in ~28px black over deep white space, with the product input as the only object
- Product-as-hero: the actual ChatGPT input (rounded ~24px container, ghost placeholder, circular up-arrow send button bottom-right) stands in for a marketing graphic
- Two-radius system: chips, inputs and buttons at full 9999px pills against editorial cards clipped to a precise 6.08px radius
- Black/white-only core UI: #000000 text, #ffffff canvas, #e5e7eb hairline borders, muted #666666 secondary, no accent colour anywhere in chrome
- Tightly tracked display type (-0.03em) so headlines read carved rather than set; weights stay 400/500/600
- Pill filter row under the input (Talk with ChatGPT / Research / API Platform / Stories / More) as lightweight secondary navigation
- Near-absent elevation: one barely-there shadow (rgba(0,0,0,0.02) 4px 6px) on the CTA only; separation comes from whitespace not shadow stacking
- Minimal top nav: wordmark left, flat text links, a search glyph, a ghost "Log in" pill beside a solid black "Try ChatGPT" pill with arrow
Do not copy
- The OpenAI wordmark and blossom/hexagon logo mark
- The custom OpenAI Sans typeface (use a neutral grotesque substitute)
- The literal "What can I help with?" line and ChatGPT product chrome
- "Try ChatGPT" and the named nav labels (Research/Products/Business/Foundation)
- The specific editorial photography and pastel gradient story cards
- The exact 6.08px card radius as a signature; it is brand-specific quirk not a borrowable token
