We’re rolling out Gemini 4 Argon in Antigravity to paid Google AI Pro subscribers today. Demand has been incredible and we've scaled capacity deliberately to get here. We’ve rolled out a separate weekly-only Argon quota for Pro on top of the existing Gemini bucket for 3.8 Flash so you have the best of Gemini for all your tasks.

From Sundar to Sergey, the level of direct engagement from Google executives is second to none. I remember having Sergey in a random chat, tracking how we were responding to a customer issue on a Sunday evening. I remember thinking to myself: "This guy could be on a yacht somewhere and instead he's here concerned why this HTTP error code is not the right one for this case"

Gemini 3.8 Live is truly impressive and lets you build low-latency, multilingual experiences such as this little app I built for my @pollenrobotics Reachy Mini.

Can you discover skills mid-session and use them right away? Or lazy load the skills you need based on a "seed skill" that downloads the right one just-in-time? 🤔
I've been messing around with this, and wrote up some examples ... seroter.com/2026/08/31/you-c…

Gemini 3.6 Flash & 3.5 Flash-Lite: our goal was to push those models a lot on real world tasks & efficiency, what's your honest feedback after 24h?

That's a wrap for Google I/O Connect Berlin 2026 :)
It was an absolute honor to share the stage with such an incredible crew: @SeraAndroid, @rickyrobinett, @anomisSi, @FMuntenescu & @Paul_Kinlan! And live-demoing during the keynote together was a lot of fun(and only slightly nerve-wracking😅)!
Beyond the talks, the best part of these events is always the energy of the community. Connecting with builders, GDG members, GDEs, and customers reminds me why we do what we do.
Thank you to everyone who stopped by to chat or watch our sessions, and a huge thank you to everyone behind the scenes who helped make this happen🙏 !
Until next time!🚀

Google's new Interactions API lets the server hold your Gemini conversation, so you stop resending the whole chat each turn, which cuts multi-turn cost. The split is clean: history lives server-side, while you keep per-turn control of tools, system prompt, and config.
Today we are shipping the Interactions API into GA, our new API designed to let you orchestrate across models and agents in the same interface, and is our new default API going forward. Interactions sets the stage for the new era of Agents : )

We’ve root caused and mitigated the high rates of output text looping in Gemini 3.5 Flash. The new model export is rolled out. We’ve reset everyone’s weekly Gemini quotas so that you can give it a try in Antigravity asap!

Gemini models are now accessible to millions of Apple developers through Apple’s Foundation Models framework and natively within Xcode. You can now easily swap between local and cloud inference using a shared API surface to build next-generation agentic app experiences, increase development velocity, and offload heavy workloads to the cloud. Additionally, you can use agentic coding assistance from Gemini in Xcode to accelerate multi-step development tasks.

The last three Antigravity CLI releases this week shipped a bunch of improvements and fixes. My favorite: the new LaTeX rendering engine. No more raw $$, just beautiful math equations right in your terminal.
