  • Context Length Optimization: Handle longer conversations without slowdown
  • Memory Usage Dashboard: Real-time visibility into memory consumption

๐Ÿ“ฑ Startup Speed Breakthrough

Jan now starts in seconds, not minutes:

  • Cold Start Optimization: 5x faster first launch
  • Background Services: Core services start in parallel
  • Lazy Loading: Only load components when needed
  • Configuration Caching: Settings load instantly
  • Progressive Initialization: UI appears immediately, features load progressively

๐Ÿ”ง Model Management Overhaul

Streamlined model experience:

  • One-Click Downloads: Simplified model acquisition
  • Download Resume: Interrupted downloads continue automatically
  • Parallel Downloads: Download multiple models simultaneously
  • Storage Optimization: Automatic cleanup of unused model files
  • Model Recommendations: AI suggests optimal models for your hardware

๐Ÿ’พ Storage Efficiency

Dramatic reduction in disk usage:

  • Model Compression: 30% smaller model files without quality loss
  • Duplicate Detection: Automatically removes duplicate models
  • Incremental Updates: Only download model changes, not entire files
  • Smart Cleanup: Removes temporary files and caches automatically
  • Storage Analytics: See exactly whatโ€™s using your disk space

๐ŸŒ Network Optimizations

Faster downloads and better connectivity:

  • CDN Integration: Download models from the closest server
  • Connection Pooling: Efficient network resource usage
  • Retry Logic: Automatic recovery from network interruptions
  • Bandwidth Adaptation: Adjusts download speed to network conditions
  • Offline Mode: Better handling when internet is unavailable

๐Ÿ” Performance Monitoring

New tools to understand performance:

  • Real-time Metrics: See inference speed, memory usage, GPU utilization
  • Performance History: Track performance over time
  • Bottleneck Detection: Identify whatโ€™s slowing down your system
  • Benchmark Tools: Compare performance across different configurations
  • Performance Profiles: Save optimal settings for different use cases

๐Ÿ› Critical Fixes

Major stability improvements:

  • Fixed memory leaks during long conversations
  • Resolved GPU driver compatibility issues
  • Eliminated random crashes during model switching
  • Fixed model corruption during interrupted downloads
  • Resolved race conditions in multi-threaded operations

Technical Details

This release includes fundamental changes to our inference engine, memory management, and GPU acceleration systems. While backwards compatible, you may notice different memory usage patterns and significantly improved performance.
