One prompt. Every answer.
Send a single message to all four models and compare side by side. Try a sample prompt:
YouExplain quantum computing to a 10-year-old.
ChatGPT
OpenAI
Imagine a coin that’s both heads and tails until you look at it. Quantum computers use bits like that, so they can try lots of answers at the same time.
Gemini
Google
Normal computers use 0s and 1s. Quantum ones use “qubits” that can be both at once — so they explore many paths together instead of one by one.
Claude
Anthropic
Think of a maze. A normal computer tries one path at a time; a quantum computer can feel out many paths at once, then point you to the way out.
Grok
xAI
It’s a computer that cheats at coin flips — every bit is heads AND tails until you peek. That weirdness lets it crunch enormous problems fast.
