The entire world seems to be talking about DeepSeek. But how good is it really? Today, I put it up against the best I’ve ever seen: Gemini Advanced 1.5 Pro with Deep Research.

Developers can game benchmarks. So I put these 2 models through a real world test, asking a complex question I actually needed the answer to.

Let’s see who wins!

Doing Real World Research

The question I asked grew out of research I’m doing for my work as an angel investor.

I’ve heard that there is only one size of IUD available in the United States. Some women find them too large and experience a lot of pain during and after insertion.

Since I invest in startups, I got to thinking…”Is there a company here?”

Not knowing much about IUD’s, I decided to ask my new friends DeepSeek and Gemini Deep Research.

Here’s the prompt I used: “in the United States, is there only one size of Mirena IUD available?”

Let’s see what they come up with…

DeepSeek R1

DeepSeek gave a good answer, but it didn’t cite any sources. It’s hard to know if the information is accurate.

It also neglected to mention the Paragard IUD, which can be a good option for some women.

Overall, DeepSeek’s answer is a good start but lacks depth. Let’s see how Gemini does…

Gemini Advanced 1.5 Pro with Deep Research

Gemini Deep Research starts by making a research plan. It lets me modify the plan if I want to before the research begins, which is an awesome feature. But Gemini’s plan sounded great, so I just approved it.

Gemini’s result stunned me.

It produced a 4 page report with 13 citations from highly reliable sources like the Cleveland Clinic and Mirena itself. It gave a wide range of IUD options with highly specific info on each one.

It even dug into a section of the Mirena website that is only for health care providers, somewhere I’d be highly unlikely to go on my own.

I checked some of this info on the websites Gemini cited. Everything I checked was 100% accurate.

I’ve never seen anything like this. Reading Gemini’s report, I was reminded of the first time I used the internet.

This is truly next level.

From the research Gemini presented, it sounds like there are a variety of IUD sizes out there already. So, investing in new types of IUD may not make sense.

Wrap-Up

Gemini’s answer was incredibly useful. The great citations gave me confidence in the result — the confidence to act.

That’s what so many AI tools are missing. They feel more like a toy than a useful product.

Gemini feels like an incredibly smart and diligent research assistant. I’d have to pay someone at least $40,000 a year to do research like this for me, even if I hired in the Philippines or other developing markets.

Gemini does it for $20/month. It also works dramatically faster than any human, 24 hours a day.

DeepSeek isn’t bad for a new model. What’s more, it was cheap to build and it’s cheap to run. But if you’re looking for the best, DeepSeek isn’t it.

Gemini still rules the roost.
