* DSPy Benchmark Comparison Framework
|
|
*
|
|
* Comprehensive benchmarking suite for comparing multiple models across

|
* quality, performance, cost, learning, and diversity metrics.
|
|
*
|
|
* Features:
|
|
* - Multi-model comparison with statistical significance
|
|
* - Scalability testing (100 to 100K samples)
|
|
* - Cost-effectiveness analysis
|
|
* - Quality convergence tracking
|
|
* - Diversity analysis
|
|
* - Pareto frontier optimization
|
|
* - Use case recommendations
