Excited to share one of the things I've been working on: Gemini 3.5 Flash Cyber: a lightweight, highly capable model built to help the security community find and patch vulnerabilities at scale. https://t.co/ldf6KH7hQN

We’ve just published our AI Control Roadmap, bringing security to AI agents: dynamic, task-based permissions, continuous monitoring, and controls like chain-of-thought so we can catch and contain harmful behavior even if alignment is imperfect. https://t.co/TQSOwLA2iU

Happy for @Google to take part in this work for a more secure digital ecosystem for everyone.

[Demis Hassabis @demishassabis]

Excited to launch Gemini 3.1 Pro! Major improvements across the board including in core reasoning and problem solving. For example scoring 77.1% on the ARC-AGI-2 benchmark - more than 2x the performance of 3 Pro. Rolling out today in @GeminiApp, @antigravity and more - enjoy!

Introducing Lyria 3, our latest and most advanced music model, available in the Gemini App starting today : )

Go from idea, image, or video to music in seconds!

[Heather Adkins - Ꜻ - Spes consilium non est @argvee]

.@Google is both observing ongoing activity related to the misuse of AI, and taking action based on these continual insights to strengthen both our security controls and Gemini. More here: https://t.co/6diZzUrysE

[Demis Hassabis @demishassabis]

Gemini 3 Deep Think is now available for Google AI Ultra subscribers in the @GeminiApp, incorporating our gold medal winning IMO and ICPC technologies! 🏅With its parallel thinking capabilities it can tackle highly complex maths & science problems - enjoy!

[Sundar Pichai @sundarpichai]

Introducing Gemini 3 ✨

It’s the best model in the world for multimodal understanding, and our most powerful agentic + vibe coding model yet. Gemini 3 can bring any idea to life, quickly grasping context and intent so you can get what you need with less prompting. 

Find Gemini 3 Pro rolling out today in the @Geminiapp and AI Mode in Search. For developers, build with it now in @GoogleAIStudio and Vertex AI. 

Excited for you to try it!

1/ Gemini 3 in action, a quick🧵 

You can give Gemini 3 anything (images, pdfs, scribbles, etc) and it will create whatever you like: an image becomes a board game, a napkin sketch transformed into a full website, a diagram could turn into an interactive lesson.

[Kevin Hou @kevinhou22]

Today, our team launched Google Antigravity.

- Agent-first IDE powered by Gemini 3 Pro 🧠
- Browser control to test your apps automatically 🤖
- Agent Manager to orchestrate parallel agents ♾️

Stoked to keep shipping with the @antigravity team. This is going to be fun.

Private AI Compute combines the privacy you expect of on-device AI with the best and latest Gemini models in the cloud. By using one seamless Google stack, we're uniquely able to offer this high standard of security. https://t.co/2Agrzg4cg6

We’re seeing a shift in adversarial use of AI, with attackers moving from simple productivity gains to experimenting with more novel capabilities. https://t.co/cyq0UfivOn

[Heather Adkins - Ꜻ - Spes consilium non est @argvee]

We’re excited to see the security and OSS communities engage on vulnerability disclosure in light of new AI technologies that we believe will enable both defenders and attackers alike. Existing and emerging norms around disclosure are important debates, and we’ve noted the feedback. Thanks! Also want to share some additional thoughts. 1/10

[Google DeepMind @GoogleDeepMind]

CodeMender has already created and submitted 72 high-quality fixes for serious security issues in major open-source projects. 🛠️

It can instantly patch new flaws as well as rewrite old code to eliminate entire classes of vulnerabilities – saving developers significant time.

[Google DeepMind @GoogleDeepMind]

Software vulnerabilities can be notoriously time-consuming for developers to find and fix.

Today, we’re sharing details about CodeMender: our new AI agent that uses Gemini Deep Think to automatically patch critical software vulnerabilities. 🧵

[Jakob Bauer @jkbr_ai]

Something we discovered by accident: what happens if we start Genie 3 from a video and a completely unrelated prompt? Turns out the model really, really wants to make it work, to the point where it emulates itself.
The prompt in this one is about a trex on a tropical island.

[Heather Adkins - Ꜻ - Spes consilium non est @argvee]

Today as part of our commitment to transparency in this space, we are proud to announce that we have reported the first 20 vulnerabilities discovered using our AI-based "Big Sleep" system powered by Gemini — https://t.co/0sgPlazqaq

[Sundar Pichai @sundarpichai]

We’re bringing a version of Deep Think that achieved gold-medal status at IMO to Ultra subscribers in the @Geminiapp (+ the official version is now in the hands of mathematicians). 

Toggle it on when reasoning through complex scientific literature, tackling a coding problem that requires careful consideration of time complexities - or anything else @DemisHassabis considers a fun Friday night:)

[Sundar Pichai @sundarpichai]

New from our security teams: Our AI agent Big Sleep helped us detect and foil an imminent exploit. We believe this is a first for an AI agent - definitely not the last - giving cybersecurity defenders new tools to stop threats before they’re widespread.
