[Feature Request] Add Model Version Comparison Tool #828

Overview

The current CSGHub platform would benefit from a model version comparison tool that allows users to easily compare different versions of the same model, including their performance metrics, parameters, and deployment configurations.

Current Behavior

• Users need to manually check different model versions
• No side-by-side comparison of model metrics
• Difficult to track changes between versions

Proposed Solution

Add a comparison feature that would:

• Show side-by-side comparisons of model versions
• Display key differences in parameters and configurations
• Visualize performance metrics between versions
• Include a diff view for model cards and configuration files

User Benefits

1. Faster decision-making when choosing model versions
2. Better version control and tracking
3. Easier identification of performance improvements
4. Enhanced model governance

Technical Considerations

• Integration with existing model management system
• Database schema updates for storing comparison data
• UI/UX changes in the frontend (Vue.js)
• API endpoints for comparison functionality

Acceptance Criteria

• Side-by-side comparison view implemented
• Performance metrics visualization
• Configuration diff viewer
• Version history timeline
• Export comparison results
• API documentation updated

Additional Context

This feature aligns with CSGHub's goal of providing enterprise-level model management and would enhance the platform's compatibility with existing MLOps workflows.

Environment

• CSGHub Version: 1.1.0
• Deployment: On-premise
• Browser: Latest Chrome/Firefox
