Gemini 3 Pro Is Now on Overchat AI

What is Gemini 3 Pro?

Gemini 3 Pro is Google's most intelligent AI model, as of November 2025. Just like Gemini 2.5 Pro, the previous best model which will now be depreciated, it can process text, images, video, audio, and write code.

‍

When comparing the Gemini 3 Pro vs Gemini 2.5 Pro, the new model scores 1,501 on the LMArena benchmark, while the Gemini 2.5 Pro scores 1,451.

‍

The model is particularly well suited to advanced workflows. Google specifically points out that it’s best at:

‍

• Learning — synthesize information across multiple formats and languages
• Building — generate interactive code and visualizations from complex prompts
• Planning — execute multi-step workflows with consistent decision-making

‍

The Gemini 3 Pro is available in two versions: there is the base version and then there is the enhanced reasoning model, Gemini 3 Pro Deep Think, built on top of the base model.

‍

Both absolutely crush it in major benchmarks:

‍

‍

These scores are the highest in the world. If you need a model for coding, math, or reasoning, look no further than Gemini 3.5 Pro.

‍

Gemini 3 Pro vs Other AI Models

If you’re wondering how Gemini 3 Pro compares to other top AI models, here’s what the benchmarks have to say:

‍

Gemini 3 Pro vs Gemini 2.5 Pro

The leap in performance compared to the previous model is absolutely massive, especially in math. The numbers speak for themselves:

‍

‍

Gemini 3 Pro is nearly 50x better math than Gemini 2.5 Pro!

‍

Gemini 3 Pro vs Claude Sonnet 4.5

Claude Sonnet 4.5 launched in September 2025 as Anthropic's flagship model, and it’s universally trusted and loved by developers and businesses. But Gemini 3 Pro crushes it in the benchmarks. Claude only wins on one coding test.

‍

‍

Claude Sonnet 4.5 just about edges ahead on SWE-bench Verified (a coding test) by 1%. That's the only benchmark where it beats Gemini 3 Pro.

‍

Gemini app also integrates directly with Google Workspace, so, by extension, if you use Gmail, Docs, Sheets, or Drive, the new model is also available there.

‍

AI Mode in Search

Gemini 3 Pro is now powering AI Mode in Google Search, and, as Google stated, this is the smartest search experience the company has ever created. The new AI mode supports entirely new experiences, powered by AI, with unusual visual layouts and even interactive simulations.

‍

Interestingly, this is the first time Google shipped a new Gemini model in Search on launch day. You can access AI Mode directly from the Google Search homepage.

‍

For Developers

Developers can access Gemini 3 Pro through multiple platforms:

‍

• Google AI Studio — Free tier available for testing and prototyping
• Vertex AI — Enterprise-grade deployment on Google Cloud
• Gemini CLI — Command-line interface for developers
• Google Antigravity — New agentic development platform

‍

Gemini 3 Pro is also available on third-party platforms like Cursor, GitHub Copilot, JetBrains, Replit, and more.

‍

Gemini 3 Pro Pricing

Gemini 3 Pro pricing is competitive with other frontier models:

‍

• Input tokens — $2.00 per million tokens (≤200K), $4.00 per million (>200K)
• Output tokens — $12.00 per million tokens (≤200K), $18.00 per million (>200K)
• Context caching — $0.20–$0.40 per million tokens

‍

For comparison, GPT-5.1 costs $1.25 input / $10 output, while Claude Sonnet 4.5 costs $3 input / $15 output

‍

What Can You Do With Gemini 3 Pro?

Google designed Gemini 3 Pro around three core capabilities: learning, building, and planning. Here's what that means in practice.

‍

Learning

Gemini 3 Pro excels at synthesizing information across multiple formats and languages. It can process text, images, video, audio, and code simultaneously.

‍

Google showed examples like:

‍

• Deciphering handwritten recipes in different languages and compiling them into a family cookbook
• Analyzing academic papers and generating interactive study materials with code
• Breaking down video lectures into flashcards and visualizations

‍

The model's 1 million-token context window means you can feed it entire research papers, long videos, or massive datasets in a single prompt.

‍

Building

Gemini 3 Pro tops the WebDev Arena leaderboard at 1487 Elo. It's exceptional at zero-shot generation and handles complex prompts with rich, interactive output.

‍

Google's demos included:

‍

• Coding a retro 3D spaceship game from a simple prompt
• Building detailed 3D voxel art that can be deconstructed and remixed
• Creating playable sci-fi worlds with shaders and physics

‍

The model generates richer visualizations and deeper interactivity than previous versions. It's built for developers who want to go from idea to prototype fast.

‍

Planing

On Vending-Bench 2, which simulates managing a vending machine business, Gemini 3 Pro maintained focus for a full simulated year. It generated significantly higher returns than competing models.

‍

In the real world, this translates to better performance on multi-step workflows — research projects, complex analysis, strategic planning.

‍

Bottom line: Gemini 3 Pro handles the kinds of tasks that require deep reasoning, technical precision, and the ability to work with massive amounts of information.

‍

Bottom Line

Gemini 3 Pro is Google's most intelligent AI model and currently the highest-ranked model in the world, and it’s already available in Overchat AI. If you need the smartest model, this is currently the best choice, as it beats GPT-5.1, Claude Sonnet 4.5, and Grok 4.1 on nearly every major benchmark.
