Which is the new king of AI

We compare Gemini 3 against ChatGPT 5.1 and Claude 4.5: which model is more powerful, which has better features, and which option is better.

After months of anticipation and numerous rumors about its features and release, Google has finally announced Gemini 3 , its new language model that boasts greater power than its predecessor and is already included in some of its products and services. Google also claims that its new AI offers superior performance compared to ChatGPT 5.1 or Claude 4.5 , currently two of the most advanced models, and asserts that it is more capable in programming tasks and multimodal understanding.

But is Google really right? We compared Gemini 3 with ChatGPT 5.1 and Claude 4.5 to find out which will be the new AI king in 2025 and which of these three models is worth using. We analyzed the performance differences through various benchmarks and tests, reviewed the key features of each model, and compared their prices, as well as the advantages and limitations of their free plans.

And although it’s difficult to choose between one and the other, the comparison of Gemini 3 vs ChatGPT 5.1 vs Claude 4.5 can be useful to know which model to use depending on your use case.

Gemini 3 vs ChatPGT 5.1 vs Claude 4.5, what do the performance tests say?

One of the most useful methods for comparing AI performance is through synthetic benchmarks . These measure the capabilities and accuracy of AI in providing answers in different scenarios, including academic reasoning, mathematics, coding, and more.

In LMArena , one of the most popular AI benchmarks, Gemini 3 has achieved a score of 1,501 , the highest ever for an artificial intelligence model, surpassing both GPT-5.1 (with 1,442 points) and Claude 4.5 (with 1,449 points).

In other types of tests, such as academic reasoning using the Humanity’s Last Exam, Gemini 3 Pro, the more powerful variant of the new model, achieved a score of 37.5%, compared to 26.5% for GPT-5.1 and 13.7% for Claude Sonnet 4.5. Google plans to release a Deep Think version of Gemini 3 later, which has scored up to 41% on this test.

These tests have allowed Google to boast that Gemini 3 is the world’s most advanced AI in terms of multimodal understanding . However, it doesn’t offer superior performance in all tasks. While Gemini 3 represents an improvement in coding compared to version 2.5, Claude 4.5 continues to reign supreme in programming, achieving scores of 77.2% in SWE-Bench tests.

Which AI is more natural?

One of the things we look for most when using an AI model, like ChatGPT or Gemini, is that it offers natural, genuine responses without any embellishment. This is precisely one of the main new features of Gemini 3. Google emphasizes that its new AI tells you what you need to hear, without sugarcoating or difficult-to-understand expressions. It is now, therefore, more concise and direct.

This is something we also see in Claude 4.5. This model, in fact, has always stood out for the naturalness of its responses and for offering concise information. Therefore, it’s difficult to choose one model over another, as it depends on the type of answers you’re looking for.

In any case, ChatGPT 5.1 is a step behind in this aspect , because unlike Gemini 3 or Claude 4.5, it does not break down the information in such a precise way.

Gemini 3 vs GPT-5.1 vs Claude 4.5, prices and which free version is better

Gemini 3, ChatGPT 5.1, and Claude 4.5 can all be used with a chatbot, available on both the web and mobile via a dedicated app. However, Gemini 3 is currently only available as a trial version accessible exclusively to paying users with Google AI Plus or Pro.

In any case, Google has also launched Gemini 3 in the AI ​​mode of its search engine , which allows for more advanced and faster answers, with relevant information and additional options, such as the ability to obtain illustrations, templates, etc.

However, you should know that to unlock all the features of ChatGPT 5.1 and Claude 4.5, a subscription to their respective Premium services is also required. They all offer a similar price.

In the case of Google, the Google AI Plus plan , which grants you immediate access to Gemini 3 Pro (albeit somewhat limited), costs €7.99 per month. Google AI Pro, which offers more comprehensive access to Gemini 3 Pro, costs €21.99 per month. ChaGPT, on the other hand, offers a Go plan with expanded access to GPT-5 for €9.99 per month, while its Plus plan costs €23 per month.

Finally, Claude 4.5 has a Pro plan for $20 a month or $200 a year, which allows somewhat more extensive access to its most advanced model.
