A real answer from our test runs

GPT-6 Luna

You put $2,000 in a savings account that pays 5% interest a year, compounded once a year. How much interest have you earned after 3 years, to the cent? Show your working briefly, then end with a line that says "Final answer: " followed by the answer alone.

GPT-6 Luna · passed our check · September 27, 2026

Interest earned = $2,000 × (1.05)³ − $2,000 = $315.25

Final answer: $315.25

One question, three answers

The same everyday summarization prompt, “An email thread in one sentence”, sent to GPT-6 Luna, Claude Sonnet 5, and Gemini 3.1 Pro: GPT-6 Luna passed, Claude Sonnet 5 failed, and Gemini 3.1 Pro passed.

The prompt: An email thread in one sentence (everyday)

Give a one-sentence summary, at most 30 words, of this email thread.

From Rosa (Mon 9:02): The printer says the brochures can't ship until the 18th, not the 11th. Paper shortage.
From Idris (Mon 9:40): The trade fair is on the 20th, so the 18th still works if we pick them up ourselves.
From Rosa (Mon 10:15): Fine by me. I'll drive to the printer on the 18th. Can someone book the van?
From Idris (Mon 10:31): Booked the van for the 18th, 8:00 to 12:00.

GPT-6 Luna
Passed: Graded 4.3 of 5 on average (lowest 3).
```
The brochures will be ready on the 18th, and Rosa will pick them up using the van Idris booked for 8:00–12:00.

Questions

How do I ask AI a question?

Type your question in the box and send it. Say what you need the answer for and how long it should be; a clear question gets a better answer from any model.

Why ask more than one AI?

Because they don't always agree. On 17 of the 50 prompts in our test runs, at least one of the 15 models gave a reply that failed its check; on the other 33, all of them passed. When an answer matters, a second model is a cheap check.

Can I ask several AIs at once?

Yes, once you've signed in: Compare sends one question to 2 or 3 models and shows the answers side by side. Each answer counts as one message of its model; on the free trial, each is one of your 5 free messages. The free message with no account goes to one model, GPT-6 Luna.

Does it search the web?

The free message with no account doesn't. Signed in, web search works inside your 5 free messages; on a paid plan a search counts as one more message of the model in use.
