Next-Generation AI Model Playground

A sophisticated real-time AI model interaction platform with streaming capabilities, built with Next.js 15 and React 19.

Features

  • ✨ Real-time AI model interaction with streaming responses
  • 📊 Live metrics tracking (tokens/sec, total tokens)
  • 🔄 Automatic retry logic with exponential backoff
  • 🔧 Configurable model parameters
  • 📱 Progressive Web App (PWA) support
  • 🔌 Offline functionality
  • ⚡ Performance optimized with React memoization
  • 📐 LaTeX equation support
  • 🎨 Dark/Light mode support

Quick Start

# Install dependencies (use legacy peer deps due to React 19 RC)
npm install --legacy-peer-deps

# Start development server
npm run dev

# Build for production
npm run build

# Start production server
npm start

Architecture Overview

Core Components

  1. Playground (components/playground/playground.tsx)

    • Main interface component
    • Handles user input and AI interactions
    • Manages conversation state

  2. Message System

    • MessageWindow: Virtualized message display
    • MessageItem: Individual message rendering
    • LaTeX equation support via KaTeX
    • Code syntax highlighting

  3. Model Controls

    • Temperature adjustment
    • Top-P configuration
    • Frequency/Presence penalty settings

  4. Error Handling

    • Error boundaries for component isolation
    • Automatic retry logic
    • Sentry integration for monitoring

State Management

  • React hooks for local state
  • IndexedDB for conversation persistence
  • Local storage for user preferences

Performance Considerations

  1. Optimizations

    • Component memoization
    • Virtualized list rendering
    • Service worker for offline support
    • Asset caching strategies

  2. Memory Management

    • Message virtualization
    • Efficient state updates
    • Cleanup on unmount

Error Handling

  1. Retry Logic

    • Exponential backoff
    • Configurable attempts
    • Error context preservation

  2. Monitoring

    • Sentry integration
    • Error logging
    • User feedback

Future Improvements

  1. Features

    • Multiple model support
    • Conversation branching
    • Export/Import conversations
    • Collaborative features

  2. Technical

    • WebSocket implementation
    • Stream compression
    • Worker thread processing
    • Enhanced caching strategies

Known Limitations

  1. Browser Support

    • Service workers require HTTPS
    • IndexedDB storage limits
    • PWA installation requirements

  2. Performance

    • Initial load time with full bundle
    • Memory usage with long conversations
    • Mobile device considerations

Edge Cases

  1. Network

    • Intermittent connectivity
    • Failed retry attempts
    • Partial message delivery

  2. User Input

    • Large message handling
    • Special character processing
    • Rate limiting

  3. Storage

    • Quota exceeded handling
    • Data corruption recovery
    • Cross-device sync limitations

Development

Prerequisites

  • Node.js 18+
  • npm or yarn
  • Modern browser with service worker support

Environment Setup

  1. Clone the repository
  2. Install dependencies with npm install --legacy-peer-deps
  3. Create .env.local with required variables
  4. Start development server
