About FrugalGPT

FrugalGPT is a research framework for using large language models (LLMs) more efficiently by reducing cost while maintaining or improving performance. It combines multi-model query routing, ensemble and fusion strategies (including thought-level and model-level fusion), and dynamic coordination across zero-shot and few-shot prompts. Compatible with multiple LLM APIs and evaluated across diverse benchmarks, FrugalGPT helps teams build cost-efficient, high-quality AI toolchains for diverse domains and tasks.
