Ensure your account is a Google AI Ultra member or holds a paid Gemini API key. Other users are advised to join the waitlist first. When you see the “Thinking” or “Gemini 3 Pro” option appear in the chat interface, you can confidently switch to it.
Currently, Gemini 3 Pro is exclusively available to Google AI Ultra subscribers and paid Gemini API users. However, the good news is that as an integrated AI platform, GlobalGPT has already integrated Gemini 3 Pro, allowing you to try it for free.
What is Gemini 3?
Gemini 3 is a next-generation large language/multimodal model launched by Google DeepMind. The company claims it demonstrates significant improvements in complex reasoning, code generation, and tool invocation.
Core Capabilities
- Deep Reasoning – Gemini 3 Pro features the innovative “Deep Think” functionality, enabling human-like deep thinking by evaluating multiple possibilities and checking its own logic before answering complex questions.
- Native Multimodal – The model is fundamentally designed to seamlessly understand and process text, images, audio, video, and code.
- Extended Context Window – Supports up to 1 million tokens of input context and 64,000 tokens of output, ideal for processing long documents and complex conversations.
- Agentic Workflows – Specially optimized for autonomous coding agents and complex zero-shot tasks. With the newly released Bash tools, it can navigate file systems and drive development processes.
- “Vibe Coding” – Supports generating complete applications from natural language descriptions without traditional programming syntax.
Who can immediate access?
According to the latest information:
- If you have subscribed to Google AI Ultra (Ultra tier) or possess a paid Gemini API key, you can access Gemini 3 Pro immediately.
- Other users (such as Free Tier users, Pro tier subscribers, Code Assist Standard users, etc.) may need to join a waitlist for activation.
- Media reports indicate that Free/paid Gemini subscribers (in certain regions/on certain devices) may also see Gemini 3 options, though functionality may be limited.
How to Enable Gemini 3 on Desktop/Mobile
Here’s a universal process:
- Accedere al proprio sito Gemini account (e.g., via Google account)
- In the chat interface, locate the “Model Switch” dropdown menu. By default, it may display “Fast” (i.e., the older model/version 2.5).
- Fast: Answers quickly (Gemini 2.5)
- Thinking: Thinks through complex topics (Gemini 3 Pro)
- If “Thinking” or “Gemini 3 Pro” appears on the page, select it to ensure you’re using the new Gemini 3.
- If you only see older options like “2.5 Flash” or “2.5 Pro,” your account hasn’t been granted access to Gemini 3 yet—it may still be rolling out in phases.
Notes & Tips
- Even if you’ve subscribed to a higher tier, Gemini 3 may not appear immediately as Google is currently rolling it out in phases.
- If you don’t have access yet: Consider upgrading your subscription plan (e.g., Ultra/API paid) or directly joining the waitlist.
- When using the model, ensure the model label is indeed Gemini 3 (or Pro version) to avoid poor experiences from using older versions.
- Access delays or version differences may occur across regions/devices. Waiting patiently or trying different devices/accounts may help.
