After several leaks, Google has finally debuted its latest Gemini 3 family of large language models. The flagship model, Gemini 3 Pro, replaces the 2.5 Pro model that was first unveiled in March 2025. Google’s announcement comes hot on the heels of OpenAI’s GPT-5.1 model, which only released a week ago for all ChatGPT users.
Gemini 3 boasts better reasoning and multimodal capabilities. In fact, Google’s testing indicates that the new model beats OpenAI’s GPT-5.1 in almost every single AI intelligence benchmark. It’s also vastly better at coding as my colleague Mishaal showcased by building entire Android apps in little time.
Theoretical benchmarks aside, though, what’s actually new with Gemini 3 and how does it stack up against GPT-5.1 in the real world? I tested both AI models to find out.
Gemini 3 vs GPT-5.1: What’s new? While most of Gemini 3’s quality upgrades are rather invisible, there are a few ways in which Google’s latest model offers a flat-out better experience than GPT-5.1. First off, Google is debuting what it calls “generative experiences”. Essentially, the AI model can now build animations and interactive UI interfaces right within your browser to explain complex topics.
The feature’s utility extends beyond educational content too. Google’s blog post showcased how Gemini 3 can generate rich “visual layouts” that you can interact with, complete with sliders, editable text fields, colorful tables, images, and other web elements. You can see a demo of this feature in the video below, where the chatbot generates a fully interactive interest rate calculator.
Google has also improved Gemini 3’s agentic capabilities. You could already ask Gemini to fetch information from your email or calendar, but the new model can handle multi-step commands too. For example, you can now ask the chatbot to book a car for your next trip and it will not only look through email but also browse the internet through a simulated browser to find an available car from a rental agency.
Gemini 3’s generative layouts feature is slowly rolling out to all users, but Google is only offering advanced agentic mode to AI Ultra subscribers for now. In other words, you’ll need to pay $200 per month for Google’s highest-end AI subscription for the feature.
Gemini 3 can perform real-world tasks on your behalf, but it's not a free feature for now.
ChatGPT can also browse the internet via an Agent mode that was released earlier this year, and you don’t need a subscription to use it. However, the chatbot cannot read your email or access your calendar and reminders the way Gemini can. Google is also leading with the generative layouts feature, although you may not end up using it for most prompts.
