About AI Battle Arena
AI Battle Arena is HT Hub's most ambitious tool — watch the world's leading AI models debate any topic in real time, side by side, with a panel of judge AIs scoring each round. Pick a topic, choose contestants from 9 frontier models (GPT-4o Mini, Claude Haiku 4.5, Gemini 2.5 Flash, Llama 4 Maverick, Mistral Small, Qwen, Grok, DeepSeek, and more), and the debate begins. Each model takes turns arguing its position, responding to opponents, and refining its case across multiple rounds. The judge panel scores on logic, evidence quality, persuasiveness, and originality. Tournament mode runs 8 models through a single-elimination bracket. The arena uses OpenRouter as a unified gateway, so you don't need API keys for any of the models — just pick and play. A public leaderboard tracks which models win most often across topic categories. Free, no signup, mobile-friendly.
