CATArena: New AI Tournament Platform Emerges to Evaluate Learning Abilities of LLM Agents

A team of researchers has unveiled CATArena, a new evaluation platform designed to rigorously assess the learning abilities of LLM agents. The platform tackles limitations in current benchmarks that primarily focus on end-to-end performance in fixed scenarios, often leading to score saturation and increased reliance on expert annotations. CATArena emphasizes learning ability, both self-improvement and peer-learning, as key to agent evolution toward human-level intelligence. The platform features an iterative, competitive peer-learning framework. Agents refine and optimize their strategies through repeated interactions and feedback. This framework systematically evaluates their learning capabilities, unlike existing benchmarks. CATArena incorporates four diverse board and card games with open-ended scoring, offering tasks without explicit upper score limits. This approach enables continuous and dynamic evaluation of rapidly advancing agent capabilities. Experimental results involving both minimal and commercial code agents demonstrate that CATArena provides reliable, stable, and scalable benchmarking for core agent abilities, particularly learning ability and strategy coding. The platform's open architecture and extensibility also allows for its adaptation to new domains and tasks, further expanding its utility in evaluating future intelligent agents.
