1 ChatGPT vs Gemini 3 - Black Hole Coding Battle (HTML/CSS/JS)

Description: Four AI models, one prompt.
I asked ChatGPT, Gemini to write a single self-contained HTML file that creates a 10–15 second looping animation of a black hole:

"Write HTML/CSS/JS code simulating a black hole pulling in nearby stars and planets, with light bending around the event horizon and an accretion disk glowing."

In this video you’ll see how each AI:

Uses HTML + CSS + JavaScript in one file

Animates buildings, lights and flying objects

Creates a smooth looping square video of a sci-fi city

Watch to the end and tell me in the comments:
Which AI made the best black hole — ChatGPT or Gemini?
