GardenBench: A lightweight, daily evaluation of LLM capabilities

Benedict Cummins-Mburu, Mariana Garcia Mejia, Oscar Heath +4

We introduce GardenBench, a benchmark with 11 test suites that evaluate the capabilities of Large Language Models (LLMs) across a range of tasks. By systematically prompting LLMs w…
