How to compare AI models side by side in Whizi
Run the same prompt against Claude, GPT, and Gemini in parallel, rank the outputs, and keep only the answer that best fits your work.
Why side-by-side comparison matters
The biggest mistake we see in AI workflows is picking a favorite model and using it for everything. Writing tone is best in Claude; structured extraction is often best in GPT; long-context research is best in Gemini. Side-by-side comparison gives you a five-second check on which model is actually best for the task in front of you.
Prompts that highlight model differences
- Writing tone: "Write a warm, professional follow-up email to a client who missed a deadline."
- Structured extraction: "Extract every date and dollar amount from this paragraph into a JSON array."
- Long reasoning: "Explain the three most common tradeoffs when choosing between SQL and NoSQL for a product analytics workload."
Workflow checklist

Common questions
How many models can I compare at once?
Up to three on Pro plans, more on Powerhouse. Two is the most common and the clearest to read.
Does side-by-side use more of my monthly messages?
Yes, each model counts as one message. Many users find it pays for itself by catching bad answers before they ship.
