Model Performance

Resource Monitoring

# Monitor Ollama resource usage
docker stats ollama

# Check model loading status
docker exec ollama ollama ps

# Monitor LibreChat performance
docker logs librechat-api

# Check database connections
docker exec librechat-mongo mongosh --eval "db.stats()"

Performance Optimization

  • Model Selection: Choose appropriate models for hardware
  • Batch Processing: Optimize for concurrent requests
  • Caching: Implement response caching where appropriate
  • Resource Limits: Set appropriate resource limits

Scaling Considerations

  • Secure Downloads: Secure model download and installation
  • Access Restrictions: Limit model access to authorized users
  • Resource Limits: Prevent abuse through resource limits

Model Updates

Update Process

  1. Model Evaluation: Evaluate new models for community needs
  2. Testing: Test new models in development environment
  3. Community Input: Gather community feedback on model selection
  4. Deployment: Deploy approved models to production
  5. Monitoring: Monitor model performance and usage

Version Management

  • Model Versioning: Track different versions of models
  • Rollback Procedures: Rollback to previous model versions
  • Update Notifications: Notify users of model updates
  • Migration Support: Help users migrate to new models

User Support

Common Issues

  • Model Not Loading: Troubleshoot model loading problems
  • Slow Response: Address performance and speed issues
  • Connection Errors: Resolve connectivity problems
  • Feature Problems: Help with LibreChat feature usage

Support Procedures

  1. Issue Identification: Identify the specific problem
  2. Log Analysis: Review relevant service logs
  3. Resource Check: Verify system resources are adequate
  4. Configuration Review: Check service configurations
  5. Solution Implementation: Apply appropriate fixes
  6. User Communication: Keep users informed of resolution

User Education

  • Model Selection: Help users choose appropriate models
  • Best Practices: Teach effective prompting techniques
  • Feature Usage: Guide users through available features
  • Privacy Awareness: Educate users about privacy features

Model Governance

Model Selection Criteria

  • Performance: Model quality and response accuracy
  • Resource Requirements: Hardware and memory requirements
  • License Compatibility: Compatible with community values
  • Community Needs: Alignment with community requirements

Community Input

  • Model Requests: Process for requesting new models
  • Usage Feedback: Gather feedback on model performance
  • Feature Requests: Process for requesting new features
  • Governance Integration: Involve community in model decisions

Ethical Considerations

  • Bias Mitigation: Address potential model biases
  • Content Guidelines: Ensure model outputs follow community guidelines

  • Responsible Use: Promote responsible AI usage

Troubleshooting

Common Problems

  • Model Loading Failures: Models fail to load or initialize
  • Out of Memory: Insufficient memory for model operation
  • Connection Issues: LibreChat cannot connect to Ollama
  • Performance Issues: Slow response times or timeouts

Diagnostic Commands

# Check Ollama status
docker exec ollama ollama version

# Test model inference
docker exec ollama ollama run llama3 "Hello, world!"

# Check LibreChat API status
curl -f http://localhost:3080/api/health

# Check database connectivity
docker exec librechat-mongo mongosh --eval "db.adminCommand('ping')"

Resolution Steps
