Gemini 3.1 pro model not available

[heckcoder]

Description

Gemini 3.1 Pro is unavailable or not selectable in the Gemini CLI for Google AI Pro subscribers. An error message states that access is not granted, even though the model is accessible in the Gemini Web App and AI Studio.

System Information

• Gemini CLI Version: [Run 'gemini --version' and paste here]
• OS: [e.g., Windows 11, macOS Sequoia, Ubuntu 24.04]
• Subscription Tier: Google AI Pro / Gemini Advanced

Steps to Reproduce

1. Open Gemini CLI.
2. Run /settings and ensure previewFeatures is set to true.
3. Restart the CLI.
4. Run /model to select a model.
5. gemini-3.1-pro-preview is either missing from the list or returns "It seems like you don't have access" when manually specified.

Expected Behavior

As an AI Pro user, Gemini 3.1 Pro should be available for selection as per the official rollout announcement.

Actual Behavior

The CLI returns: "Model 'gemini-3.1-pro-preview' was not found or is invalid" or "It seems like you don't have access to gemini-3.1-pro-preview."

Troubleshooting Already Attempted

• Updated CLI to the latest version using npm install -g @google/gemini-cli@latest.
• Logged out and logged back in using gemini login.
• Verified access in Google AI Studio (works there).

Yeah, this happened to me too!

I am a paid subscriber using v0.29.0-nightly.20260203.71f46f116 but I only have access to gemini-3-pro-preview through Preview Features in /settings.

Haven't tried #20206 yet but hopefully it fixes it 👍

[hedges333]

This will be required for all users within 2 weeks, even free tier users, or it will break access. I received an e-mail today from googleaistudio-noreply@google.com with the following:

"Action required: Gemini 3 Pro Preview will be discontinued on March 9, 2026 in favor of the new model. Please upgrade to Gemini 3.1 Pro Preview beforehand to prevent any service disruption. Additionally, on March 6, 2026, we will switch the gemini-pro-latest alias to point to the new 3.1 Pro model."

It seems like the real fix moving forward is to support the "gemini-pro-latest" model alias.

Thank you.

➜  visitor git:(main) ✗ 

how to fix this ? i dont see any menu options settings for preview

[samveen]

I can choose the correct model via --model gemini-3.1-pro command line argument (fixed by #19676 (and release 0.31) ), but I cannot select it manually via the /model command.

[jtrecok]

I can choose the correct model via --model gemini-3.1-pro command line argument (fixed by #19676 (and release 0.31) ), but I cannot select it manually via the /model command.

Chosing this did not fix it for me. Running 0.31 Tried both google Auth and API key. 3 flash and 2.5 pro work fine. but Unable to 3/3.1 pro.

[rudolphjacksonm]

I can choose the correct model via --model gemini-3.1-pro command line argument (fixed by #19676 (and release 0.31) ), but I cannot select it manually via the /model command.

The CLI starts up with this flag and says the model in use is gemini-3.1-pro, however when I ask Gemini directly which model it is using, it says 2.5-pro. Something is definitely not joined up here.

[bdlgq-mike]

In Australia. See this for most of the day, for the past week: "Trying to reach gemini-3.1-pro-preview". It basically only works between 6am and 12pm. From there it is extremely spotty. If i try to use Gemini after 4pm, it quite literally never connects.

[generik0]

I can choose the correct model via --model gemini-3.1-pro command line argument (fixed by #19676 (and release 0.31) ), but I cannot select it manually via the /model command.
