Understanding Composite Indices
- Intelligence Index: Aggregated score combining MMLU-Pro, GPQA, and HLE benchmarks - measures overall reasoning and knowledge capabilities
- Coding Index: Composite metric from LiveCodeBench, SciCode, and LiveCodeBench Review - evaluates programming proficiency across multiple languages
- Math Index: Combined score from AIME, AIME 2025, and MATH-500 benchmarks - assesses mathematical reasoning from high school to competition level
Key Comparison Metrics
- Benchmark Scores: Standardized tests measuring intelligence, coding, math, and specialized capabilities - higher percentages indicate better performance
- Pricing Analysis: Compare input and output token costs across models - critical for budgeting API usage and scaling applications
- Performance Metrics: Throughput (tokens/second) and latency measurements for real-time application planning
- Context Windows: Maximum token capacity for processing documents and maintaining conversation history
How to Compare AI Models Effectively
Performance vs Cost
Balance benchmark scores against token pricing - flagship models offer 10-15% better performance but cost 5-10x more than smaller alternatives
Task-Specific Selection
Prioritize relevant indices: coding index for development tasks, math index for STEM applications, intelligence index for general reasoning
