## 🎯 Objective
Build sampling interface components, create model selection and preference UI, implement sampling result visualization, and add cost/performance monitoring.

## 📋 Requirements
- Build comprehensive sampling interface components
- Create intuitive model selection and preference UI
- Implement sampling result visualization and analysis
- Add real-time cost and performance monitoring
- Create Gradio accordion for sampling controls
- Build interactive model selection interface
- Add real-time cost and performance feedback
- Implement sampling history and analysis features

## 🛑 Constraints & Rules
- Must integrate seamlessly with existing Gradio interface
- UI must be intuitive for non-technical users
- Performance monitoring must be real-time
- Cost tracking must be accurate and transparent
- All UI components must be accessible
- Mobile compatibility required

## ✅ Acceptance Criteria (Definition of Done)
- [ ] Sampling UI components implemented: Gradio interface with sampling controls
- [ ] Model selection working: Interactive model preference interface
- [ ] Result visualization functional: Sampling results displayed clearly
- [ ] Cost monitoring active: Real-time cost tracking and display
- [ ] Performance feedback working: Response time and quality metrics
- [ ] Sampling history implemented: Historical analysis and trends
- [ ] User guidance available: Help and tooltips for sampling features
- [ ] Integration complete: Seamless integration with existing UI
- [ ] Accessibility validated: WCAG compliance for sampling interface
