Google has officially launched the Gemini 3 large model, and this article details seven official usage channels. Google AI Studio offers a full-featured free experience with support for context lengths up to millions of tokens; the Gemini app is suitable for general users but has usage limits; Search AI Mode is available only to select subscribed users. Additionally, the newly introduced Antigravity IDE supports multi-model collaboration, the CLI tool is designed for developers, and the API and Vertex AI serve individual and enterprise-level development needs. These channels cover everything from everyday chatting to professional development, showcasing Google’s comprehensive AI ecosystem.

Who has such prestige that even OpenAI CEO Sam Altman and Musk are liking this large model?

Yes, it's Gemini 3.

Yesterday, Google officially released Gemini 3, and I wrote a breakdown article—then the comments section exploded.

Many users are asking: How do I use it? Where can I use it? Is it free?

I spent the whole night organizing 7 official channels (I have to say, Google’s product lineup is really confusing).

This tutorial gets you set up with Gemini 3 in 5 minutes.

Highlight: I've pinned all the channel links mentioned below in the comments. Don't forget to check.

01｜Google AI Studio: The Most Recommended Free Channel

Recommendation rating: ⭐⭐⭐⭐⭐

If I had to choose just one, I’d close my eyes and recommend AI Studio.

I’ve been recommending this platform for over a year now, without exaggeration.

Why?

Not only is it free, but it's also abundant.

The Gemini 3 Pro in AI Studio is the full-power version, with a context length of up to 1 million tokens—no compromises, no cuts.

The playability is also very strong.

You can set the model's thinking level, media_resolution, and temperature.

Other features are also fully equipped.

You can not only chat, but also create drawings, use voice, video chat, and generate videos—all with ease.

The recently updated Build mode is a powerful tool for Vibe Coding.

Supports parameter tuning, multimodal input, and generating shareable AI applications.

The only thing to note is that Google has default permission to use your conversation data from AI Studio to train models.

Remember not to send sensitive information.

02｜Gemini App: Web and Mobile App

Recommendation rating: ⭐⭐⭐⭐

This is the most accessible channel for regular users.

The web platform has been fully upgraded to Gemini 3.

The mobile push is still ongoing.

On the Gemini mobile app, some accounts have already been granted Gemini 3 access, while others (even paid ones) are still on 2.5 Pro.

Available for free, but with strict usage limits—approximately 5 times per day (far below AI Studio above).

Google's student discount is more recommended—get a free year of Gemini AI Pro membership; Google officially extended the application period for this offer yesterday.

03 | Google Search AI Mode: The AI Form of Search

Recommendation rating: ⭐⭐⭐

This is the first time Google has integrated a new model into search on its release day.

After all, this is Gemini 3.

It's a good feature, but I can only give it three stars.

Currently available only to select Gemini AI Pro and Ultra subscribers.

How do you verify whether a grayscale release has been pushed to you?

Open the Google Search homepage and select AI Mode on the far right of the search box to enter.

In the top-left corner of AI Mode, if you can switch models (as shown in my screenshot above), congratulations—you can now fully enjoy using Gemini 3.

04 | Google Antigravity: Another Cursor?

Recommendation rating: ⭐⭐⭐⭐⭐ (temporary)

This may have been the most underrated release yesterday.

It became so popular that users couldn’t even log in, and those who did often saw nothing but a spinning circle.

Later, Google urgently released an updated version.

So, what is Antigravity?

You can simply think of it as the Google version of Cursor.

At its core, it is an AI IDE, and Google has upgraded it into a multi-agent collaborative development environment.

Supports Gemini 3, and also supports Claude Sonnet 4.5 and OpenAI’s open-source model.

Importantly, it's free for a limited time, but with rate limits.

05 | Gemini CLI: A Blessing for Terminal Enthusiasts

Recommendation rating: ⭐⭐⭐

Give Gemini CLI three stars because its use cases are very limited.

This is a tool exclusively for developers.

That means you should have some experience using the command line.

The Gemini CLI can do many things: chat, read folders, write code, execute Shell commands, perform Google searches, and connect to MCP servers.

Installation is also simple and requires Node.js 18 or higher:

npm install -g @google/gemini-cli

Then just execute the gemini command.

Gemini 3 access is prioritized for Ultra subscribers.

Pro users and free users can apply for access here:

06 | AI Studio API: Individual Developers

Recommendation rating: ⭐⭐

Generating an API key in AI Studio is the most straightforward method.

Gemini 3 API pricing is tiered:

Within 200,000 tokens: $2 per million tokens for input, $12 per million tokens for output
Over 200,000 tokens: Input at $4 per million tokens, output at $18 per million tokens

Slightly more expensive than GPT-5.1, but slightly cheaper than Claude Sonnet 4.5.

07 | Vertex AI: Enterprise Solutions

Recommendation rating: ⭐⭐

This is Google Cloud's enterprise-grade AI platform.

Designed for enterprise users.

Or individual users who have registered for Google Cloud (GCP) and are still within the $300 free credit limit.

Vertex AI is more powerful than AI Studio, supporting both cloud deployment and on-premises installation, with a complete MLOps toolchain and enterprise-grade data isolation.

The process is slightly more complex, requiring you to create a Google Cloud account, set up a project, and enable the Vertex AI API.

New users will receive a $300 credit valid for 3 months from Google, perfect for trying things out for free.

Conclusion

In 24 hours, I tried all seven of these channels.

Overall impression: Google is really going all out this time.

Although the product line is slightly disorganized, the overall ecosystem layout is quite comprehensive.

It provides access to Gemini 3 in nearly every scenario.

From browser to terminal, from individuals to enterprises, there’s something for everyone.
