Grok 4 was once considered the strongest candidate, but made many serious mistakes in the final match, such as losing pieces early and making unreasonable moves.
o3 showed outstanding ability to analyze tactics and understand chess strategy, especially in the middle and endgame. Grok 4, although strong in the early stages of the tournament, showed weakness in the final games and could not show the ability to handle complex situations.
Elsewhere, Google's Gemini 2.5 Pro took third place after beating o4-mini 3.5-0.5. Despite the win, Gemini was judged to have played at a lower quality than o3, with many messy and error-prone games.
The AI Kaggle 2025 competition, which took place from August 5 to 7, featured eight large language models (LLMs) competing in a single-elimination format. The eight representatives included OpenAI's o3 and o4-mini, Google's Grok 4, Gemini 2.5 Pro and Gemini 2.5 Flash, Anthropic's Claude 4 Opus, and China's Deepseek R1 and Kimi R2.
This is Google's experimental event to evaluate the potential of AI in the fields of strategic thinking and general intelligence.
