Cross-Model Consistency of AI-Generated Exercise Prescriptions: A Repeated Generation Study Across Three Large Language Models
Researchers benchmarked consistency across GPT-4.1, Claude Sonnet 4.6, and Gemini 2.5 Flash when generating exercise prescriptions repeatedly. GPT-4.1 achieved highest semantic stability (0.955) but produced entirely unique outputs each time, revealing a critical tension between reproducibility and diversity that matters for clinical AI deployment.
