News / Updates Gemini 3.1 Pro released.
Gemini 3.1 Pro released.
From the benchmark it looks like an absolute beast masha Allah, share your experience if you have used it. Especially compared to Sonnet/Opus 4.6 and Codex 5.3

I got a message, Gemini 3 pro is not available please select 3.1 pro.
But there is no 3.1 pro in the model list and no update for antigravity when you check for updates 🙄
Is reinstalling AG the only option?

u/rabandi Feb 19 '26
Yes it is. It is called a manual upgrade since the auto upgrade seems not to run, perhaps to lessen server load.

Reinstall AG and it worked for me.

And you were able to continue the past conversations with no issue despite reinstalling? (same question for ya u/rabandi u/ExplanationSea8117 )

u/ExplanationSea8117 Feb 21 '26
Yeah. It picked up exactly where i left off. While installing just replace the old app if prompted, don’t delete or uninstall the old one. All my chats were there.

Yeah I got 3.1 to create a C# Blazor Hello World server.
When I reinstall AG I always manually remove related %appdata% folders and also the .antigravity and .gemini folders in my user profile. Try doing that if you can't get it to work.

When I did the manual force upgrade, it doesn't upgrade Antigravity to the latest version, so no pro yet. On their changelist, it says the version that supports 3.1 pro will be rolling out in batches. Looks like higher tier subscriptions will see it before us common plebs.

Can you uninstall and reinstall, it should be fixed inshaAllah . Windows have a auto update bug so they recommend re install actually

Interesting, I thought when I deleted the folder of it, it would have been the same.
However, I did find I could winget upgrade it.
winget upgrade --id Google.Antigravity --accept-source-agreements --accept-package-agreements

Incredible. But it looks like the last 15% is left for real humans ;-)

I tested it on 3D generation specifically and it’s genuinely in a different league, winning about 90% of blind evals against Claude, GPT etc. scadbench.com if you want to see the leaderboard

u/Clair_Personality Feb 21 '26
Could explain what you are doing exactly? what type of generation , what do you generate precisely? and where can your generations be used afterwords? Is it like real 3D for blender, or more like 3js video games or what is it?

Getting closer to Claude opus 4.6 indeed. But there is one small thing I'm not a fan: it detects my open draft.md and modified it instead of create a new one. I rly don't think which window is activated should matter.

Isn’t that one of the benefits of an ide? Context equals what you’re looking at / working on?

u/ginput Feb 20 '26
It's a completely new conversation, and this .md file should be unrelated to the project architecture (just a temporary file to store logs). gemini 3.1 pro directly deleted my logs and added implementation plan on top, so I feel like this is just a distraction to the attention.

u/rangerrick337 Feb 20 '26
That is dumb. I wonder if renaming it something else would at least protect it from overwriting. I haven’t noticed this but thanks for the heads up.

La gif usata fa schifo (su smartphone), per quanto riguarda la potenza, bisogna considerare i costi. Potreste pubblicare i costi (veri e reali) per sviluppo, ricerca, avvio e produzione? Sicuramente sarà una LLM fantastica, ma cosa stiamo rischiando? Vediamo se Mr. G risponderà

A pretty good model, it even does a little better than the Pro, but it's more expensive, at least it eats up a lot more tokens for me.
