Model Architecture

UIGEN-X-4B-0729 implements Reasoning Only from the Qwen3 family - combining systematic planning with direct implementation. The model follows a structured thinking process:

1. Problem Analysis — Understanding requirements and constraints
2. Architecture Planning — Component structure and technology decisions
3. Design System Definition — Color schemes, typography, and styling approach
4. Implementation Strategy — Step-by-step code generation with reasoning

This hybrid approach enables both thoughtful planning and efficient code generation, making it suitable for complex UI development tasks.

Prompt Structure Guide

Basic Structure

To achieve the best results, use this prompting structure below:

[Action] + [UI Type] + [Framework Stack] + [Specific Features] + [Optional: Style]

Examples

Simple Component:

Create a navigation bar using React + Tailwind CSS with logo, menu items, and mobile hamburger menu

Complex Application:

Build a complete e-commerce dashboard using Next.js + TypeScript + Tailwind CSS + shadcn/ui with:
- Product management (CRUD operations)
- Order tracking with status updates  
- Customer analytics with charts
- Responsive design for mobile/desktop
- Dark mode toggle
Style: Use a clean, modern glassmorphism aesthetic

Framework-Specific:

Design an Angular Material admin panel with:
- Sidenav with expandable menu items
- Data tables with sorting and filtering
- Form validation with reactive forms
- Charts using ng2-charts
- SCSS custom theming

Advanced Prompt Techniques

Multi-Page Applications:

Create a complete SaaS application using Vue 3 + Nuxt 3 + Tailwind CSS + Pinia:

Pages needed:
1. Landing page with hero, features, pricing
2. Dashboard with metrics and quick actions
3. Settings page with user preferences
4. Billing page with subscription management

Include: Navigation between pages, state management, responsive design
Style: Professional, modern with subtle animations

Style Mixing:

Build a portfolio website using Svelte + SvelteKit + Tailwind CSS combining:
- Minimalist layout principles
- Cyberpunk color scheme (neon accents)
- Smooth animations for page transitions
- Typography-driven content sections

Tool Calling & Agentic Usage

UIGEN-X-4B-0729 supports function calling for dynamic asset integration and enhanced development workflows.

Image Integration with Unsplash

Register tools for dynamic image fetching:

{
  "type": "function",
  "function": {
    "name": "fetch_unsplash_image",
    "description": "Fetch high-quality images from Unsplash for UI mockups",
    "parameters": {
      "type": "object",
      "properties": {
        "query": {
          "type": "string", 
          "description": "Search term for image (e.g., 'modern office', 'technology', 'nature')"
        },
        "orientation": {
          "type": "string",
          "enum": ["landscape", "portrait", "squarish"],
          "description": "Image orientation"
        },
        "size": {
          "type": "string",
          "enum": ["small", "regular", "full"],
          "description": "Image size"
        }
      },
      "required": ["query"]
    }
  }
}

Content Generation Tools

{
  "type": "function", 
  "function": {
    "name": "generate_content",
    "description": "Generate realistic content for UI components",
    "parameters": {
      "type": "object",
      "properties": {
        "type": {
          "type": "string",
          "enum": ["user_profiles", "product_data", "blog_posts", "testimonials"],
          "description": "Type of content to generate"
        },
        "count": {
          "type": "integer",
          "description": "Number of items to generate"
        },
        "theme": {
          "type": "string", 
          "description": "Content theme or industry"
        }
      },
      "required": ["type", "count"]
    }
  }
}

Complete Agentic Workflow Example

# 1. Plan the application
response = model.chat([
    {"role": "user", "content": "Plan a complete travel booking website using React + Next.js + Tailwind CSS + shadcn/ui"}
], tools=[fetch_unsplash_image, generate_content])

# 2. The model will reason through the requirements and call tools:
# - fetch_unsplash_image(query="travel destinations", orientation="landscape") 
# - generate_content(type="destinations", count=10, theme="popular travel")
# - fetch_unsplash_image(query="hotel rooms", orientation="landscape")

# 3. Generate complete implementation with real assets
final_response = model.chat([
    {"role": "user", "content": "Now implement the complete website with the fetched images and content"}
])
