Summary

The Week 4 leaderboard update for the Chatbot Arena introduces new chatbots, including Google PaLM 2 and Anthropic Claude-instant-v1. The Elo ratings based on 27K anonymous votes from April to May 2023 show GPT-4 leading at 1225, followed by Claude-v1 and Claude-instant-v1. Google PaLM 2, ranked 6th, exhibits some deficiencies, including strict regulations leading to higher refusal rates for certain questions, limited multilingual capabilities, and unsatisfactory reasoning abilities. Smaller models like Vicuna-7B have shown competitive performance, suggesting that quality datasets are crucial. The Arena aims to refine its evaluation methods to better assess long-tail capabilities of LLMs and welcomes community contributions to add more models.

Signals

name description change 10-year driving-force relevancy
Emergence of Smaller Competitive Models Smaller models like Vicuna-7B achieving high ratings against larger models. Shift from larger models dominating to smaller models being competitive. In a decade, smaller, efficient models may dominate the market, focusing on performance over size. Advancements in data curation and fine-tuning techniques leading to improved model efficiency. 4
Regulatory Impact on Chatbot Responses PaLM 2’s stricter regulatory framework leading to refusal to answer questions. Shift from open, conversational AI to more regulated, cautious responses. Future chatbots may enforce stricter compliance, limiting user interaction and creativity. Increasing concerns over AI safety and ethical considerations. 5
Multilingual Limitations of AI Models Current models like PaLM 2 struggling with non-English languages. Transition from predominantly English-focused models to multilingual capabilities. In ten years, we may see robust multilingual models capable of seamless cross-language interaction. Globalization and the need for inclusive technology solutions. 4
Need for Long-Tail Capability in LLMs Recognition of the importance of complex reasoning tasks in LLMs. Shift from basic conversational abilities to advanced reasoning and nuanced understanding. In a decade, LLMs may achieve high proficiency in complex reasoning tasks. Demand for AI in real-world applications requiring sophisticated problem-solving. 5
Community-Driven Model Development Community feedback driving the addition of new models and adjustments in leaderboard. Shift from top-down development to collaborative, community-influenced model evolution. Future AI development may increasingly rely on community input and collaborative approaches. Desire for diverse perspectives and rapid iteration in AI technology. 3

Concerns
