How we verify

Evidence: Article or interviewA newsletter, journalist or interview account of what happened.

Context: In a comparison test: from a head-to-head chatbot review, not a standalone agent test.

Outcome

TechRadar's editor-at-large gave ChatGPT (GPT-5), Claude (Sonnet 4.5) and Google AI Mode (Gemini 2.5 Pro) the same Prime Day gift brief: five fun tech gifts under $100, smaller than a bread box, ideally heavily discounted. He found all followed the brief closely; Gemini answered fastest and returned the most varied list and the best breakdown, Claude pulled its picks from TechRadar's own guides, and ChatGPT leaned toward Amazon devices.

Prompt Original prompt

Exact prompt as published in the source.

I want to buy five tech gifts for friends and am hoping you can help find the best stuff on Amazon during Prime Day (happening now). The parameters are that they have to be smaller than a bread box, cost less than $100, and be fun or even whimsical. It would be great if each one represents a significant discount.
Optional stronger version

Our rewrite with extra checks. The poster didn't test it.

Run this task now, exactly as written below. Everything you need is here, so start straight away and only stop if something required is missing or a rule below tells you to.

Goal: Find gift options on sale that fit my per-gift budget and size limits.

Fill in before running:
- Number of gifts: [NUMBER]
- Budget per gift: [AMOUNT]
- Store and sale: [STORE / EVENT]
- Style of gift: [e.g. fun, practical]

Rules:
- Only include items currently on sale, with the regular and sale price and the date checked.
- Explain how each item fits every limit.
- Flag any item that needs a paid subscription to work.
- Don't add to cart or buy.
- If a site asks for a login, a CAPTCHA or payment details, stop and hand control back to me.
- Ask for my OK before you pay, book, send, submit or cancel anything.
- Check facts that can change (prices, opening hours, dates, availability, rules) against the official source, and tell me anything you couldn't verify.
- Check the price history before buying to confirm the discount is real.

Output: A gift list with prices, discount, link and fit notes.

You'll know it worked when: every item meets the budget and limits, with prices I can confirm.

Before you finish: re-read my goal and constraints, check your answer against each one, and list anything you assumed or couldn't confirm.

    A TechRadar editor asked ChatGPT, Gemini and Claude what discounted tech to buy on Prime Day. Gemini focused on deals but overstated one: it said Sony WH-1000XM5 headphones were 50% off when they were actually 20% off at $198 (was $248). ChatGPT tailored picks to his interests from past chats but was less tuned in to actual discounts, and Claude, which knew least about him, gave fairly generic deals.

    Tom's Guide's Amanda Caswell gave ChatGPT, Gemini and Alexa+ the same school supply list: follow it, stick to required quantities, pick reasonably priced items and skip optional ones. Gemini built an Instacart cart, skipped optional items, asked her to approve colours and totalled about $60-$90 ($105 with the optional water bottle). ChatGPT, on her Walmart account, followed the list carefully but slowly for $92.55; Alexa+ added the optional items and reached $251.48.
