🏆 The AI Chess Championship: GPT vs Claude vs Gemini vs Grok

Artificial intelligence is no longer just powering our phones, search engines, or writing assistants — it’s now entering the chess arena in ways we’ve never seen before. While engines like Stockfish and Komodo remain the undisputed kings of pure calculation, a new type of AI has emerged: large language models (LLMs).

These models — designed for reasoning, creativity, and conversation — are now being tested in the royal game. And what better way to explore their potential than a 4‑team AI Chess Championship featuring the newest, most advanced AI models from the biggest labs in the world?

Introduction of the contenders

• GPT‑5 (OpenAI)
  Recently demonstrated strong reasoning ability by earning a score of 15 on the American Invitational Mathematics Examination (AIME), a level comparable to top high school math competitors.

• Claude 4.0 Sonnet (Anthropic)
  The newest model in the Claude family, known for careful and structured reasoning. It has been widely adopted in business and research settings for its reliability in complex tasks.

• Gemini 2.5 Pro (Google DeepMind)
  DeepMind, famous for creating AlphaZero in 2017, continues its innovations with Gemini. The 1.5 Pro version is recognized for handling extremely long contexts in text and reasoning tasks.

• Grok‑4 (xAI)
  Developed by Elon Musk’s xAI, Grok‑2 has been integrated with X (formerly Twitter) to provide conversational assistance and real‑time knowledge to millions of users.

Rules

1. no time limits 

2. each AI is going to pair up with any other AI on one game 

3. AIs will have the chance to change illegal moves(often happens)

4.if at last two AIs tie in points their is going to be one more match between them
