GPT-4: Researchers at Stanford University have developed FrugalGPT, a system that reduces the costs of using large language model (LLM) APIs like GPT-4 and ChatGPT by up to 98% while maintaining or improving performance. The study introduces three strategies: prompt adaptation, LLM approximation, and LLM cascade. FrugalGPT enables smooth performance-cost trade-offs, offering flexible choices for LLM users and potentially helping API providers save energy and reduce carbon emissions.
