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!

[Demis Hassabis @demishassabis]

Nice progress!📈 Great work from the @GeminiApp team 💪

Gemini 3 Flash on the @ArtificialAnlys intelligence benchmark, the most cost per intelligence efficient model in the world!!!

[Google DeepMind @GoogleDeepMind]

Gemini 3 Flash gives you frontier intelligence at a fraction of the cost. ⚡

Here’s how it’s built for speed and scale 🧵

[Wes Roth @WesRoth]

Demis Hassabis says the most ignored marvel is AI’s ability to understand video, images, and audio together.

Gemini can watch a movie scene and explain the symbolism behind a tiny gesture.

This shows the model grasps concepts, not just pixels or words.

Such deep cross-media reasoning is still under-appreciated outside AI circles.

[Google AI Developers @googleaidevs]

Gemini 3 Pro is the frontier of multimodal AI, delivering SOTA performance across document, screen, spatial, and video understanding.

Read our deep dive on how we’ve pushed our core capabilities to power hero use cases across:

+ Docs: "derender" complex docs into structured code (HTML/LaTeX)
+ Screen: build robust computer agents that automate complex tasks
+ Spatial: generate collision-free trajectories for robotics & XR
+ Video: analyze sports footage using high-FPS processing with "thinking" mode

See how these capabilities are transforming workflows in education, biomedical, and law/finance → https://t.co/01lfGyKxYQ

Google cooked so hard. Not gonna lie, this feels like the future is here.

Now develop Google Glasses with enough battery power, a good chip, and a look like Ray-Bans, and you'll have an instant hit. 100%.

[Oriol Vinyals @OriolVinyalsML]

The secret behind Gemini 3?

Simple: Improving pre-training & post-training 🤯

Pre-training: Contra the popular belief that scaling is over—which we discussed in our NeurIPS '25 talk with @ilyasut and @quocleix—the team delivered a drastic jump. The delta between 2.5 and 3.0 is as big as we've ever seen. No walls in sight!

Post-training: Still a total greenfield. There's lots of room for algorithmic progress and improvement, and 3.0 hasn't been an exception, thanks to our stellar team.

Congratulations to the whole team 💙💙💙

[Google DeepMind @GoogleDeepMind]

Our first release is Gemini 3 Pro, which is rolling out globally starting today.

It significantly outperforms 2.5 Pro across the board:
🥇 Tops LMArena and WebDev @arena leaderboards
🧠 PhD-level reasoning on Humanity’s Last Exam
📋 Leads long-horizon planning on Vending-Bench 2

[Arena.ai @arena]

👨‍💻Have you tested models in the new Code Arena yet?

In this thread, we’re showcasing real Gemini 3 Pro by @GoogleDeepMind creations and the exact prompts used, all of them built inside the Code Arena. You can directly compare Gemini’s outputs against other top frontier models on real web development tasks.

Build, compare, vote, and share your own creations directly from the chat.

See examples in the thread. 🧵

[Jeff Dean @JeffDean]

Exciting expansion! @Waymo now serves the whole SF Bay Area Peninsula from SF to San Jose and is taking riders on freeways.

https://t.co/fNgqQtHB7b

[Demis Hassabis @demishassabis]

Made it to no.1 in the App Store. Congrats to the @GeminiApp team for all their hard work, and this is just the start, so much more to come!

[Google DeepMind @GoogleDeepMind]

Image generation with Gemini just got a bananas upgrade and is the new state-of-the-art image generation and editing model. 🤯

From photorealistic masterpieces to mind-bending fantasy worlds, you can now natively produce, edit and refine visuals with new levels of reasoning, control and creativity.

A quick dive into Gemini 2.5 Flash’s capabilities 🧵

[Demis Hassabis @demishassabis]

One word: relentless. just in the past two weeks, we’ve shipped:

🌐 Genie 3 - the most advanced world simulator ever
🤔 Gemini 2.5 Pro Deep Think available to Ultra subs
🎓 Gemini Pro free for uni students & $1B for US ed
🌍 AlphaEarth - a geospatial model of the entire planet
🏛️ Aeneas - deciphering ancient text (in @Nature)
🥇 Gemini gold-medal level at the IMO
🧸 Storybook - books w/art & audio @GeminiApp
♛ New @Kaggle Game Arena benchmark for LLMs
🐙 Jules, our asynchronous coding agent, out of Beta
🇬🇧 AI Mode for Search available in the UK
📔 NotebookLM Video Overviews
🔥 Gemma passed 200m downloads

Now you know why I don't get much sleep 🛌 - too busy pushing the frontier!

[Ani Baddepudi @AniBaddepudi]

gemini's still the only frontier model that supports native video input (and is amazing at it!)

incredible amount of real-world utility given how much of the world's information is increasingly in video

[Andi Marafioti @andimarafioti]

The results are in, and they're revealing. Only Gemini 2.5 pro handles 1-hour-long videos.

Performance drops sharply with duration, proving that long video understanding is still challenging. We've found the breaking points—now the community can start fixing them.📈

[Demis Hassabis @demishassabis]

Official results are in - Gemini achieved gold-medal level in the International Mathematical Olympiad! 🏆 An advanced version was able to solve 5 out of 6 problems. Incredible progress - huge congrats to @lmthang and the team! https://t.co/pp9bXF7rVj
