GEPA optimizes AI prompts by analyzing failed trajectories

Researchers have developed GEPA, a new method for optimizing prompts in complex AI systems. GEPA analyzes failed execution paths and automatically refines the prompts of the specific modules responsible for the errors. In tests across six tasks, GEPA outperformed the GRPO method by an average of 6%, achieving this with significantly fewer rollouts. AI
