Claude vs DeepSeek

The same questions, put to Claude Sonnet 5.5 and DeepSeek V4 Pro. Their answers, word for word.

“Should a small café start offering delivery? Give a clear view.”

Claude Sonnet 5.5

Probably yes, but start small. Delivery can bring in extra customers, especially at quiet times, but apps take 20-30% of each order, which can wipe out your profit. To make it work:

  • Offer only items that travel well, like coffee beans, pastries, and sandwiches.
  • Raise delivery menu prices a little to cover fees.
  • Try one app for a month and track the real profit.
  • Make sure packaging doesn't cost too much.

If orders are few or you're short on staff, skip it. Focus on dine-in and takeaway instead.

DeepSeek V4 Pro

Offering delivery can help if you have spare kitchen capacity and nearby demand, but it's not automatically right. Delivery apps take large commissions, so your profit on each order may shrink. You also need packaging that keeps food good and staff time to manage orders. Start small: test with a limited menu and your own driver or a low-cost service, track whether repeat orders justify the effort, and stop if it hurts dine-in quality or profit.

“A customer says our prices went up too much. Write a short, kind reply.”

Hi [Name],

Thank you for telling us. We hear you, and we're sorry the new prices feel like a lot. We didn't take the decision lightly. Our own costs went up, and we raised prices only as much as we needed to keep the quality you count on.

We truly value you as a customer. If there's something we can do, like suggesting a more affordable option, please let us know.

Thanks for being with us, [Your Name]

DeepSeek V4 Pro

I’m really sorry the price increase caught you off guard. Our own costs for materials and shipping have gone up significantly, and we held off as long as we could. We tried to keep the increase as small as possible while still staying in business. I truly appreciate you telling us how you feel, and I hope we can keep serving you.
