Here’s How You Can Use ChatGPT 5, Gemini Pro, and Claude Free (in 2025)

So large language models are what run today’s powerful chatbots, whether it’s ChatGPT, Gemini, Claude, or whatever you use. These models do the heavy thinking behind answers, text, and images. Usually, the best versions are behind paid plans, but there is a way to try many premium models in one place without paying.

Well, this is not a hack or some weird trick. In this article, I will talk about a website that gives access to top, best AI models free of charge, including ChatGPT Pro, Claude Pro, Gemini Advanced, Mistral, and LLaMA 3. So let’s get started.

The website I’m talking about is called LMarena. You can Google “LMarena” or go to lmarena.ai. 

Visit LMarena

When you open the site, the interface looks like a chat app, something you’re already used to.

You will see Leaderboard, where you can check the top models. Under the leaderboard, models are grouped by task, which ones are best for text, which for images, which for reasoning, and so on.

You’ll notice that there are a lot of models, and some names you might never have heard before.

1. Battle Feature

One important feature is the Battle option.

The battle option shows a side-by-side comparison between LLM models.

When you hover or click there, you’ll see a few choices, including Direct Chat and Battle. we you enter a prompt in battle mode, you will get two results. It’s up to you which one you choose. You can pick the left answer, the right answer, or say both are bad.

After you pick, LMarena shows which model produced which output. That way, you  analyse which model provides the better result, though it is subjective.

Once you select the answer, you will see which model is used to generate the output.

2. Side-by-side Feature

You will also see an option to choose your own model. There are many models listed, so you can pick any two to compare. Try different pairs and see which one performs better for your prompts.

You can compare models for text and also for images. For image generation or visual tasks, you can choose between different image models. I’m talking about premium models, not just basic ones. Premium image models are available to test, too.

3. Direct Chat Feature

If you go with Direct Chat, you can use a model directly without comparing.

When you tap Direct Chat, you can chat with one model and get outputs straight away.

This is useful when you want to use a single model for a longer session, or when you want to test how that model responds over a conversation. You can also use Direct Chat to try image model prompts and see quick results.

Why are these models free on LMarena?

Now, to answer the obvious question: why are these models free here?

How are you getting this access without paying?

The simple answer is that LMarena is a testing and benchmarking platform. AI companies let people use and test their models on the site so they can collect feedback and comparison data. Developers want to see how their models perform against others and get real user responses. For that reason, companies sometimes make premium or experimental models available on LMarena.

Because it’s for testing, there may be limits later on, but right now you can use many models without paying. That means you can try any model you want and test it for your needs before deciding to pay for a subscription somewhere else.

Hope you like this article. I tried to gather useful, educational information so it helps you explore these tools. We are in the time of AI, and it helps to learn how these tools work. If you get access to a premium model here, test it out. If you find it useful, you can consider paying for the full version later. Otherwise, you’ve saved money by trying first.

This site is a good place to explore and check different models. Let me know your thoughts. If you know other ways to test premium models for free, comment below and share them.
