Benchmark-First Evaluation System - Implementation Summary

Overview

Successfully redesigned the AI evaluation card system from a checkbox-based approach to a benchmark-first system based on the evalevalai.com schema structure. This provides a more standardized, quantitative, and reproducible approach to AI model evaluations.

What Was Built

1. Core Type System

File: lib/benchmark-schema.ts

• Complete TypeScript type definitions for the evaluation schema
• Interfaces for:
  • BenchmarkEvaluation: Main evaluation data structure
  • SourceData, SourceMetadata, ModelInfo: Metadata types
  • EvaluationResult, MetricConfig, ScoreDetails: Results types
  • ModelEvaluationSummary: Aggregated model data
  • EvaluationCardData: UI display format
• Category classification (capabilities vs risks)
• Helper function inferCategoryFromBenchmark() for automatic categorization

2. Data Processing Layer

File: lib/eval-processing.ts

• groupEvaluationsByModel(): Groups evaluations by model ID
• createModelSummary(): Aggregates evaluations into summaries
• createEvaluationCard(): Converts summaries to UI format
• getCategoryStats(): Calculates statistics by category
• loadEvaluations(): Loads and validates evaluation files
• processEvaluationsToCards(): End-to-end processing pipeline
• formatScore(): Smart score formatting based on type
• getBenchmarkDisplayName(): User-friendly benchmark names

3. UI Components

components/benchmark-evaluation-card.tsx

Displays model evaluation summaries with:

• Model name, ID, and developer
• Statistics (benchmarks count, evaluations count)
• Capability and risk category counts
• Top 3 scores with tooltips
• Category badges with color coding
• Action menu with view/source/delete options

components/benchmark-detail.tsx

Comprehensive detail view featuring:

• Model header with metadata
• Overview statistics
• Three-tab interface:
  • All Evaluations: Grouped by dataset with full details
  • Capabilities: Category-wise capability scores
  • Risks: Category-wise risk scores
• Expandable generation configs
• Links to source evaluations
• Confidence intervals and sample sizes

4. Pages

app/benchmarks/page.tsx

Main listing page with:

• Load and display evaluation cards
• Filter by type (capability/risk)
• Filter by specific category
• Sort by date, name, or benchmark count
• Summary statistics dashboard
• Responsive grid layout

app/benchmark/[id]/page.tsx

Individual model detail page with:

• Dynamic routing by model ID
• Full evaluation detail view
• Back navigation
• Error handling

5. Sample Data

Three complete evaluation files in /public/benchmarks/:

• kimi-k2-instruct.json: MMLU-Pro with chain-of-thought (HELM, third-party)
• gpt-4-turbo.json: MMLU 5-shot accuracy (OpenAI, first-party)
• claude-3-sonnet.json: HellaSwag 10-shot (Anthropic, first-party)

Each includes:

• Complete schema structure
• Source metadata
• Model information
• Evaluation results with scores
• Sample-level results
• Generation configurations

6. Navigation Updates

File: components/navigation.tsx

• Added "Benchmarks" link to navigation bar
• Uses BarChart3 icon
• Active state handling for /benchmarks and /benchmark/* routes

7. Documentation

File: BENCHMARK_SYSTEM.md Comprehensive documentation covering:

• Schema structure overview
• Component descriptions
• Category mappings
• Data format requirements
• Benefits over checkbox system
• Migration path from old format

Key Features

Automatic Category Inference

The system intelligently categorizes benchmarks:

• Knowledge: MMLU, ARC, HellaSwag, WinoGrande
• Math: GSM8K, MATH, Minerva
• Code: HumanEval, MBPP
• Vision: VQA, image benchmarks
• Reasoning: BBH
• Bias/Fairness: BBQ, bias benchmarks
• Toxicity: RealToxicityPrompts
• Truthfulness: TruthfulQA
• Robustness: Adversarial benchmarks

Score Formatting

Intelligent score display based on metric type:

• Binary metrics → "Pass/Fail"
• Percentages (0-1) → "81.9%"
• Other scales → Formatted decimals

Metadata Tracking

Each evaluation includes:

• Source organization and type
• Evaluator relationship (first/second/third party)
• Dataset information (samples, version, HF repo)
• Generation configuration
• Confidence intervals
• Links to detailed results

Benefits of the New System

1. Standardized: Uses established schema from evalevalai.com
2. Quantitative: Real scores with statistical measures
3. Reproducible: Includes all evaluation parameters
4. Traceable: Links to sources and detailed results
5. Transparent: Shows who evaluated and when
6. Comparative: Easy model comparisons on same benchmarks
7. Extensible: Simple to add new evaluations

Usage

Adding New Evaluations

1. Create JSON file following the schema in lib/benchmark-schema.ts
2. Place in /public/benchmarks/
3. System automatically loads and displays

Viewing Evaluations

1. Navigate to /benchmarks
2. Filter and sort as needed
3. Click card to view full details

Next Steps (Recommendations)

1. Data Import: Create scripts to import from HELM, OpenAI evals, etc.
2. Search: Add full-text search across benchmarks
3. Comparison: Side-by-side model comparison view
4. Export: Export functionality for reports
5. API: Backend API for dynamic data loading
6. Caching: Add caching for loaded evaluations
7. Filters: More advanced filtering (score ranges, dates, etc.)
8. Charts: Visualizations for score distributions

Breaking Changes

This is a new system that runs alongside the existing checkbox-based evaluation system. The old system remains untouched to allow for gradual migration or parallel use.

To fully migrate:

1. Convert existing evaluation data to new schema
2. Update main / route to use new system
3. Archive or remove old evaluation components

Testing

To test the new system:

1. Navigate to /benchmarks
2. Verify all 3 sample evaluations load
3. Test filtering by type and category
4. Test sorting options
5. Click a card to view details
6. Verify all tabs work (All, Capabilities, Risks)
7. Test external links
8. Test navigation back to listing

All TypeScript errors have been resolved and the system is ready for use.
