🇰🇷 Korean Learning Features Ready

Immediate Usage

# Start Korean learning NOW
cd /home/hsyyu/repo/kor2unity
tmux attach-session -t kor2unity-tui
# Type: /korean

# Check system status
python scripts/kor2unity_status.py

# Test all APIs
python scripts/test_kor2unity_api.py

Learning Modes Available

  • Korean Conversation: Real-time AI-powered practice
  • Grammar Assistance: Korean grammar explanations and examples
  • Vocabulary Building: Contextual word learning and usage
  • Cultural Context: Korean culture integration in learning
  • Progress Tracking: Session history and learning analytics

🛠️ Problem Solutions Implemented

1. Interactive Terminal Hanging (SOLVED)

  • Problem: Model inference blocked terminal interaction
  • Solution: Tmux-based TUI launching + non-blocking testing
  • Result: Korean learning runs independently of development workflow

2. Self-hosted Model Integration (ACHIEVED)

  • Challenge: Connect to local Llama 2 7B-HF and MiniGPT-4 models
  • Solution: Conda environment activation + CUDA optimization
  • Result: 13.5GB Llama model loaded and inference-ready

3. Service Orchestration (OPERATIONAL)

  • Requirement: Multiple services coordination
  • Implementation: Dedicated port allocation (8200-8299)
  • Status: MongoDB, APIs, Ollama, TUI all operational

📊 Performance Metrics
