ChatGPT vs Claude vs Gemini: Which AI Platform is Better?

If I’m going to explain which AI platform is the best, I first have to take a step back and talk about some of the basics behind these AI platforms and how they actually work.

So, first things first: what’s an LLM?

ChatGPT, Claude, and Gemini are all what’s called an LLM.

LLM is short for Large Language Model.

In plain English, an LLM is an AI program that’s been trained, or programmed, on a massive amount of data: text, articles, books, websites, videos, code, manuals, conversations, and pretty much any piece of human content, information, or knowledge that’s been available online up to this point.

Yeah… that’s a LOT of data.

And it’s been trained to analyze all of that data, categorize it, recognize patterns, and through that, it’s learned how to answer questions, explain things, reason, and so on.

So it’s not necessarily that AI is smarter than humans. It’s that it has access to more information than any single human ever could.

Let me put this into perspective. Bear with me, because it’s pretty wild:

An older version of ChatGPT, called GPT-4, was reportedly trained on roughly 13 trillion tokens of text.
A token is AI-speak for a unit of information.

A typical book contains about 100,000 tokens.

That means 13 trillion tokens works out to roughly 130 million books worth of text.

The Library of Congress, the largest library in the world, holds around 39 million actual books.

So at one point, ChatGPT had essentially been trained on the equivalent of every single book in the Library of Congress… times four.

Chances are, when you ask ChatGPT a question, it’s going to have an answer.

A genuinely avid bookworm, finishing about one book every few weeks for their entire adult life, might read somewhere around 800 to 1,000 books in a lifetime.

Do the math, and here’s what you get:

That early version of ChatGPT had access to the equivalent of more than 150,000 lifetimes worth of reading, and not just average readers either. We’re talking avid readers, people finishing a book roughly every three weeks, for an entire lifetime.

But here’s the other important part of this.

It’s not necessarily that AI is smarter than humans.

For example, if a true expert in a specific field sat down and talked to ChatGPT, Claude, or Gemini about the exact subject they’ve spent their career mastering, they’d likely arrive at similar answers, similar conclusions, and honestly, they could probably hold their own in a pretty great debate with it.

It’s just that AI has access to way more information than any single human will ever have at any given moment.

And here’s the other thing: a lot of people turn to AI specifically to come up with answers, build plans, or work through problems in areas where they aren’t the expert. In doing so, they get instant access to a vast body of knowledge they’d never otherwise be able to tap into, along with the answers, solutions, and direction that comes with it.

So, in its simplest form, an LLM is an AI program that’s been trained on, and can analyze a massive amount of content, almost instantly, recognize patterns within it, and produce answers based on everything it’s processed.

And through that training, it’s gotten extremely good at predicting what a helpful, accurate, well-structured response should look like, based on everything it’s learned.

Ok, now let’s look at how LLM works.

Who Built Them, and Why

ChatGPT comes from OpenAI, a company that’s largely focused on building broadly useful, general-purpose AI as fast as possible, rolling out new features constantly.

Claude comes from Anthropic, a company that was actually founded by former OpenAI employees, with a heavier focus on safety and building AI that’s careful, thoughtful, and less likely to confidently make things up.

Gemini comes from Google, and it’s built with deep ties to everything Google already does, Search, Workspace, YouTube, Android. It’s designed to plug directly into the ecosystem you’re probably already using.

Keep that context in mind, because it shows up in all three of the differences below.

Honestly? It explains a lot of why these three “feel” different to use, even though they’re technically doing the same basic thing under the hood.

ChatGPT feels fast and broadly useful because that’s exactly what it was built to be.

Claude feels more careful and detailed because that’s the philosophy baked into how it was trained.

Gemini feels plugged-in and current because, well, it is, literally, into Google’s entire ecosystem.

None of that makes one objectively “better” than the others. It just means they were built with different priorities, and that shows up in how they actually behave.

Okay, let’s actually answer the question.

Well… it depends on what you’re trying to do.

I use all three, every single day, but for completely different tasks.

And now that we’ve gone through the basics, hopefully that makes a lot more sense.

Since the data each one has access to, how it’s learned from that data, the input it’s gotten from millions of users, and how its reasons and replies are all genuinely different, it only makes sense that each one ends up being better suited to different tasks.

So instead of just telling you “use this one,” let me show you.

Here’s a breakdown of common, everyday tasks a small business owner might actually use AI for, and roughly how each platform stacks up.

🟢 means it’s a strong pick for that task,

🟡 means it’s decent but not the standout, and

🔴 means it’s genuinely not built for that.

This is based on general, widely-held impressions of how these platforms currently perform, not an official scientific benchmark, and these things shift fast as each company updates its models.

Remember how we started this whole thing talking about rivalries? Coke vs Pepsi, Xbox vs PlayStation, my mom and her unshakeable loyalty to Android?

Here’s the thing about this rivalry that makes it a little different from all those others: with Coke vs Pepsi, you really do just pick one and stick with it.

But with AI, you don’t have to. You’re not choosing a team here.

You’re choosing tools, and there’s nothing stopping you from having more than one in your toolbox.
So here’s my honest, practical advice on how to actually choose:

If that’s writing, lean toward Claude.

If that’s a general all-purpose assistant that can also make an image for you, lean toward ChatGPT.

If your whole business already lives inside Google, lean toward Gemini.

Try it for real work, not just a quick test. A lot of people form an opinion after one or two throwaway prompts.

Give whichever one you pick a real week of actual use, a real email, a real proposal, a real question you need answered, before deciding if it’s the right fit.

Don’t be afraid to use more than one. I do, every single day.

There’s no rule that says you have to pick a side and defend it like it’s your favorite sports team. Use the right tool for the task in front of you.

Revisit this decision every so often. This space moves fast.

What’s true about these three platforms today might shift in six months.

The good news is, switching between them, or using more than one, has basically no downside.
So, ChatGPT vs Claude vs Gemini, which one’s actually better?

Honestly, the best one is whichever one you’ll actually use, consistently, for the things you need most. That’s not a cop-out answer.

After everything we just walked through, I hope it’s clear why that’s genuinely the most honest one.

Which AI is better, ChatGPT, Claude, or Gemini?

Which AI should a small business owner start with?

Is Claude better than ChatGPT for writing?

Is Gemini worth using if I don’t use Google Workspace?

Do I need to pay for more than one AI tool?

Do all three AI platforms get their information from the same place?
