If you have encountered the message "Gemini 3.1 Pro is not available on this version. Please upgrade to the latest version," this guide will help you understand why this occurs and how to resolve it. This typically points to a version incompatibility, meaning the application or platform you are using needs an update to support Gemini 3.1 Pro.
Quick Summary: Resolving Gemini 3.1 Pro Availability Issues
- Update your application: Ensure your Gemini App, Google App (Android), or other integrated platforms are running the latest version.
- Check SDK/CLI versions: For developers, confirm your Google Gen AI SDK for Python (v1.51.0+) or Gemini CLI are up to date.
- Verify subscription tier: Access to Gemini 3.1 Pro, especially with higher usage limits, may require a Google AI Pro or Ultra subscription.
- Reinstall if necessary: For platforms like Google Antigravity, a fresh installation might resolve persistent issues.
- Understand usage limits: Be aware that even with the latest version, usage limits based on prompt complexity and subscription tier apply.
The Evolution of Gemini Models
Google officially launched Gemini 3.1 Pro on February 19, 2026. This updated AI model builds upon its predecessor, Gemini 3 Pro, and is specifically engineered for complex tasks, as detailed on the Google AI blog. Its core intelligence and logical reasoning capabilities have seen marked improvements.
For instance, on the ARC-AGI-2 benchmark, Gemini 3.1 Pro achieved a verified score of 77.1%, representing more than double the reasoning ability of Gemini 3 Pro.
The model can process extensive datasets and multimodal information, encompassing text, audio, images, video, and even entire code repositories, according to Google’s announcements and blog posts about Gemini 3.1 Pro on Gemini CLI, Gemini Enterprise, and Vertex AI. With a maximum input token size of up to 1 million tokens, equivalent to approximately 1,500 pages of text or 30,000 lines of code, and an output token size of 64,000 tokens, it handles substantial amounts of information. The knowledge cutoff for Gemini 3.1 Pro is January 2025.
Accessing Gemini 3.1 Pro
Gemini 3.1 Pro is accessible across various platforms, catering to consumers, developers, and businesses. If you are seeing an availability error, the first step is to ensure your access method is up to date.
For Developers
- Developers can access a preview of Gemini 3.1 Pro through the Gemini API in Google AI Studio.
- Other access points include the Gemini CLI, Google Antigravity, and Android Studio.
- To use Gemini 3.1 Pro in Google Antigravity, the latest version of Antigravity must be installed. Some users have reported that a reinstallation fixed the problem.
- The Google Gen AI SDK for Python requires at least version 1.51.0 for Gemini 3 API functions.
For Businesses
- The model is available via Vertex AI.
- Businesses can also access it through Gemini Enterprise.
- When using the Gen AI SDK with Vertex AI, environment variables such as
GOOGLE_CLOUD_PROJECT,GOOGLE_CLOUD_LOCATION=global, andGOOGLE_GENAI_USE_VERTEXAI=Truemust be set.
For Consumers
- Consumers can interact with Gemini 3.1 Pro through the Gemini App.
- It is also available via NotebookLM.
- For the mobile Gemini App, ensure you have the current version (at least Google App Version 16.18 for Android, Gemini App Version 1.2025.187003 for iOS/iPadOS).
- An upgrade to a Google AI subscription (Pro or Ultra) can be done via Google One in the Gemini App or on gemini.google.com.

Developers can access Gemini 3.1 Pro through various platforms, including integration with Android Studio, for building new applications.
When utilizing thinking_level, developers can adjust the model’s processing depth: LOW offers faster, lower-latency responses for simple queries, MEDIUM (available only for Gemini 3 Flash and Gemini 3.1 Pro) provides a balance of speed and reasoning, and HIGH is the default for complex prompts requiring detailed processing. The media_resolution parameter also allows for control over multimodal image processing, where higher resolutions enhance detail recognition but increase token usage and latency.

GOOGLE_GENAI_USE_VERTEXAI=TruePractical Applications and Enhanced Capabilities
Gemini 3.1 Pro’s advanced reasoning and multimodal capabilities open doors to sophisticated applications. Here are some examples of what it can do:
- It can generate website-ready, animated SVGs directly from text prompts.
- The model demonstrates its prowess in complex system syntheses, like creating a live aerospace dashboard, as highlighted in a Google AI blog post.
- Furthermore, it facilitates interactive design, enabling the coding of a 3D starling swarm simulation with hand-tracking controls, also discussed in the Google AI blog.
- Its ability to translate literary themes into functional code is evident in its capacity to design a portfolio for Emily Brontë’s "Wuthering Heights," another example from the Google AI blog.
These examples highlight its suitability for agentic performance, advanced coding, long context processing, multimodal understanding, and algorithmic development.
Understanding Usage and Limitations
While Gemini 3.1 Pro offers considerable power, users should be aware of specific usage limits, which are in place to ensure optimal service for all. The number of prompts a user can send depends on factors like length, complexity, file size, and conversation length.
Usage Limit Details
| Factor | Impact on Usage | Notes |
|---|---|---|
| Prompt Length | Longer prompts consume more tokens. | Maximum input token size: 1 million (approx. 1,500 pages of text). |
| Prompt Complexity | More complex queries require greater processing. | thinking_level can be adjusted (LOW, MEDIUM, HIGH). |
| File Size | Larger files (e.g., in multimodal inputs) use more resources. | Higher media_resolution increases token usage and latency. |
| Conversation Length | Extended conversations maintain context, consuming more tokens. | Ensure thought_signature is handled correctly for context. |
| Output Size | Longer generated responses. | Maximum output token size: 64,000 tokens. |
These limits are periodically restored, or users can upgrade their Google AI subscription to a higher tier for increased capacity, as mentioned in a Google Developers blog post about Premium AI Pro and Ultra. Pro and Ultra subscribers benefit from higher limits within the Gemini App and exclusive access to NotebookLM powered by Gemini 3.1 Pro. Users without Pro or Ultra subscriptions may experience earlier restrictions during periods of high activity, as noted in the same Google Developers blog post.
