Design System Inspired by Together AI
1. Visual Theme & Atmosphere
Together AI's interface is a pastel-gradient dreamscape built for enterprise AI infrastructure — a design that somehow makes GPU clusters and model inference feel light, airy, and optimistic. The hero section blooms with soft pink-blue-lavender gradients and abstract, painterly illustrations that evoke clouds and flight, establishing a visual metaphor for the "AI-Native Cloud" proposition. Against this softness, the typography cuts through with precision: "The Future" display font at 64px with aggressive negative tracking (-1.92px) creates dense, authoritative headline blocks.
The design straddles two worlds: a bright, white-canvas light side where pastel gradients and stats cards create an approachable platform overview, and a dark navy universe (#010120 — not gray-black but a deep midnight blue) where research papers and technical content live. This dual-world approach elegantly separates the "business" messaging (light, friendly, stat-driven) from the "research" messaging (dark, serious, academic).
What makes Together AI distinctive is its type system. "The Future" handles all display and body text with a geometric modernist aesthetic, while "PP Neue Montreal Mono" provides uppercase labels with meticulous letter-spacing — creating a "technical infrastructure company with taste" personality. The brand accents — magenta (#ef2cc1) and orange (#fc4c02) — appear sparingly in the gradient and illustrations, never polluting the clean UI.
Key Characteristics:
-
Soft pastel gradients (pink, blue, lavender) against pure white canvas
-
Deep midnight blue (#010120) for dark/research sections — not gray-black
-
Custom "The Future" font with aggressive negative letter-spacing throughout
-
PP Neue Montreal Mono for uppercase technical labels
-
Sharp geometry (4px, 8px radius) — not rounded, not pill
-
Magenta (#ef2cc1) + orange (#fc4c02) brand accents in illustrations only
-
Lavender (#bdbbff) as a soft secondary accent
-
Enterprise stats prominently displayed (2x, 60%, 90%)
-
Dark-blue-tinted shadows (rgba(1, 1, 32, 0.1))
2. Color Palette & Roles
Primary
-
Brand Magenta (#ef2cc1): The primary brand accent — a vivid pink-magenta used in gradient illustrations and the highest-signal brand moments. Never used as UI chrome.
-
Brand Orange (#fc4c02): The secondary brand accent — a vivid orange for gradient endpoints and warm accent moments.
-
Dark Blue (#010120): The primary dark surface — a deep midnight blue-black used for research sections, footer, and dark containers. Not gray, not black — distinctly blue.
Secondary & Accent
-
Soft Lavender (#bdbbff): A gentle blue-violet used for subtle accents, secondary indicators, and soft UI highlights.
-
Black 40 (#00000066): Semi-transparent black for de-emphasized overlays and secondary text.
Surface & Background
-
Pure White (#ffffff): The primary light-section page background.
-
Dark Blue (#010120): Dark-section backgrounds — research, footer, technical content.
-
Glass Light (rgba(255, 255, 255, 0.12)): Frosted glass button backgrounds on dark sections.
-
Glass Dark (rgba(0, 0, 0, 0.08)): Subtle tinted surfaces on light sections.
Neutrals & Text
-
Pure Black (#000000): Primary text on light surfaces.
-
Pure White (#ffffff): Primary text on dark surfaces.
-
Black 8% (rgba(0, 0, 0, 0.08)): Borders and subtle containment on light surfaces.
-
White 12% (rgba(255, 255, 255, 0.12)): Borders and containment on dark surfaces.
Gradient System
-
Pastel Cloud Gradient: Soft pink → lavender → soft blue gradients in hero illustrations. These appear in abstract, painterly forms — clouds, feathers, flowing shapes — that create visual warmth without literal meaning.
-
Hero Gradient: The hero background uses soft pastel tints layered over white, creating a dawn-like atmospheric effect.

Mono Micro PP Neue Montreal Mono 10px (0.63rem) 400 1.40 0.05px Smallest uppercase labels
Principles
-
Negative tracking everywhere: Every size of "The Future" uses negative letter-spacing (-0.16px to -1.92px), creating consistently tight, modern text.
-
Mono for structure: PP Neue Montreal Mono in uppercase with positive letter-spacing creates technical "label" moments that structure the page without competing with display text.
-
Weight 500 as emphasis: The system uses 400 (regular) and 500 (medium) — no bold. Medium weight marks headings and emphasis.
-
Tight line-heights throughout: Even body text uses 1.25–1.30 line-height — tighter than typical, creating a dense, information-rich feel.

5. Layout Principles
Spacing System
-
Base unit: 8px
-
Scale: 1px, 2px, 4px, 8px, 10px, 12px, 16px, 20px, 24px, 32px, 44px, 48px, 80px, 100px, 120px
-
Button/badge padding: 2px 8px (compact)
-
Card internal padding: approximately 24–32px
-
Section vertical spacing: generous (80–120px)
Grid & Container
-
Max container width: approximately 1200px, centered
-
Hero: centered with pastel gradient background
-
Feature sections: multi-column card grids
-
Stats: horizontal row of metric cards
-
Research: dark full-width section
Whitespace Philosophy
-
Optimistic breathing room: Generous spacing between sections creates an open, inviting feel that makes enterprise AI infrastructure feel accessible.
-
Dual atmosphere: Light sections breathe with whitespace; dark sections are denser with content.
-
Stats as visual anchors: Large numbers with small captions create natural focal points.
Border Radius Scale
-
Sharp (4px): Buttons, badges, tags, small interactive elements — the primary radius
-
Comfortable (8px): Larger containers, feature cards
This is a deliberately restrained radius system — no pills, no generous rounding. The sharp geometry contrasts with the soft pastel gradients.
6. Depth & Elevation
Level Treatment Use
Flat (Level 0) No shadow, no border Page background, text blocks
Contained (Level 1) 1px solid rgba(0,0,0,0.08) (light) or rgba(255,255,255,0.12) (dark) Cards, badges, containers
Elevated (Level 2) rgba(1, 1, 32, 0.1) 0px 4px 10px Feature cards, hover states
Dark Zone (Level 3) Dark Blue (#010120) full-width background Research, footer, technical sections
Shadow Philosophy: Together AI uses a single, distinctive shadow — tinted with Dark Blue (rgba(1, 1, 32, 0.1)) rather than generic black. This gives elevated elements a subtle blue-ish cast that ties them to the brand's midnight-blue dark mode. The shadow is soft (10px blur, 4px offset) and always downward — creating gentle paper-hover elevation.
7. Do's and Don'ts
Do
-
Use pastel gradients (pink/blue/lavender) for hero illustrations and decorative backgrounds
-
Use Dark Blue (#010120) for dark sections — never generic gray-black
-
Apply negative letter-spacing on all "The Future" text (scaled by size)
-
Use PP Neue Montreal Mono in uppercase for section labels and technical markers
-
Keep border-radius sharp (4px) for badges and interactive elements
-
Use the dark-blue-tinted shadow for elevation
-
Maintain the light/dark section duality — business (light) vs research (dark)
-
Show enterprise stats prominently with large display numbers
Don't
-
Don't use Brand Magenta (#ef2cc1) or Brand Orange (#fc4c02) as UI colors — they're for illustrations only
-
Don't use pill-shaped or generously rounded corners — the geometry is sharp
-
Don't use generic gray-black for dark sections — always Dark Blue (#010120)
-
Don't use positive letter-spacing on "The Future" — it's always negative
-
Don't use bold (700+) weight — 400–500 is the full range
-
Don't use warm-toned shadows — always dark-blue-tinted
-
Don't reduce section spacing below 48px — the open feeling is core
-
Don't mix in additional typefaces — "The Future" + PP Neue Montreal Mono is the pair
