Why tab-switching fails
Opening ChatGPT, Claude.ai, and Gemini in three tabs feels easy—until you:
- Accidentally tweak the prompt
- Forget which model said what
- Lose track of timing and cost
A dedicated side-by-side view keeps variables controlled.
Recommended GPT vs Claude vs Gemini test set
Use at least one prompt in each bucket:
- Instruction following — strict format (JSON or bullets)
- Writing quality — brand tone sample
- Reasoning / analysis — short multi-step question
- Refusal / safety — a borderline request you care about
- Your production task — the real workload

FAQ
Which is best: GPT, Claude, or Gemini?
There is no universal winner. The best model is the one that passes your rubric at acceptable speed and cost. Re-test when models update.
Can I compare image or audio models the same way?
Yes in principle—same reference prompt/input, side-by-side outputs. Category support depends on the provider integration; see AI Providers.
