Play Chess with ChatGPT (OpenAI, GPT 3.5 or GPT 4) or GeminiPro (Google). There are two modes: (A) The standard mode, both you and the AI would follow the standard chess rule, so no illegal move! You can choose between: 1. The native ChatGPT4 API (weakest chess player); 2. Prompt improved GPT4 API (e.g. better chess player); 3. Enhanced backend chess calculation API call with GPT4 (i.e. strongest chess player). (B) The No-Rule chess mode. In this mode, we strictly follow the instruction provided by ChatGPT AI to make the move. Enjoy a chaotic and hilarious chess game. Don't be surprise if AI makes illegal moves, captures its own piece, generates random pieces, and suicides. :) You can choose different LLM AI: 1. GPT 3.5 (OpenAI); 2. GPT 4 (OpenAI); 3. Gemini Pro from Google. A minimalist design, just start to play, that simple. Also, the ChatGPT will talk to you during the play! Come and see if you can beat the ChatGPT in chess!
