AI that works for everyone.

OpenAI builds safe artificial general intelligence for humanity. A quietly literary interface: Signifier for display moments, Söhne for system text, OpenAI Teal as the lone accent.

What this fixture exercises

Restraint as identity.

Two voices

Signifier (serif) for editorial display moments only. Söhne sans for all UI and body text. Weights cap at 600 — 700+ feels off-brand.

Teal accent

#10a37f — the lone color in an otherwise neutral system. Links, highlight badges, success path CTAs. Hairline borders (#e5e5e5) used sparingly; whitespace as primary divider.

Generous rhythm

--leading-body: 1.65. --leading-tight (Signifier display): 1.08. 96px section rhythm on desktop. Whitespace is the architecture.

Form components

Soft radius, teal focus.

12px radius on inputs; border: 1px solid #e5e5e5 at rest. Focus: border #10a37f + 3px rgba ring.
