Benchmarking Large Language Models: The blog post from LMSYS discusses the launch of Chatbot Arena, a benchmark platform for large language models (LLMs) using the Elo rating system. It highlights the platform’s ability to conduct anonymous, randomized battles between models, inviting community participation through model contributions and voting. The post also outlines the challenges of benchmarking LLMs, the desired properties of a good benchmark system, and future plans for the platform, including adding more models and improving evaluation mechanisms. Notably, the platform does not include conversation histories in its data to avoid privacy and toxicity concerns.
