DSPy SIMBA Optimizer

Goal

Optimize DSPy programs using mini-batch Bayesian optimization with statistical analysis of feedback signals.

When to Use

• Need lighter-weight alternative to GEPA
• Have custom feedback metrics (not just accuracy)
• Agentic tasks with rich failure signals
• Budget-conscious optimization (fewer eval calls)
• Programs where few-shot examples aren't critical
