Many open source projects develop comprehensive language models that can be trained to perform specific tasks. These models can provide useful responses to user questions and commands. Notable examples include LLaMA-based Alpaca and Vicuna, and Pythia-based OpenAssistant and Dolly.
New models are released every week, but the community still struggles to benchmark them properly.Because LLM Assistant concerns are often vague, a benchmarking system that can automatically assess the quality of answers is difficult to create. Human evaluation with pairwise comparisons is often needed here. Ideally, your own benchmarking system should be scalable and incremental, based on pairwise comparisons.
Few current LLM benchmark systems meet all of these requirements. Traditional LLM benchmarking frameworks such as HELM and lm-evaluation-harness provide multimetric measurements of research standard tasks. However, open-ended questions are not evaluated properly because they are not based on pairwise comparisons.
LMSYS ORG is an organization that develops large-scale models and systems that are open, scalable and accessible. Their new work presents Chatbot Arena, a crowdsourced LLM benchmarking platform with anonymous and randomized battles. Like chess and other competitive games, Chatbot Arena uses the Elo rating system. The Elo rating system demonstrates the promise of providing the desired qualities mentioned above.
They started gathering information a week ago when they opened an arena with a number of well-known open source LLMs. An example of LLM’s practical application can be found in Crowdsourced Data Collection Methods. Users can compare and contrast two anonymous models while chatting simultaneously in the arena.
FastChat, a multi-model serving system, hosted the arena at https://arena.lmsys.org. Those entering the arena are confronted with a conversation with two unnamed models. After receiving comments from both models, consumers can continue the conversation or vote for their preferred model. After voting, the identity of the model will be revealed. The user can continue the conversation with the same two anonymous models of her, or start a new battle with two new models. The system records every user her activity. Only if the model name obscures the analysis votes used. Nearly 7,000 legitimate anonymous votes have been tallied since the arena went live a week before him.
In the future, we hope to implement improved sampling algorithms, tournament procedures, and service delivery systems to accommodate more diverse models and provide more granular ranks for different tasks.
