GPT Chess

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!
