Gemini 3 launch marks Google’s latest step in AI development
Google’s Gemini 3 introduces stronger reasoning, multimodal skills and generative UI across Search, the Gemini app and enterprise tools, promising faster development and richer user experiences.
Imagine asking your phone to turn a napkin sketch into a working app while you sip your coffee and getting back a neat prototype in under a minute.
That is the everyday scene Google is pitching as it rolls out Gemini 3, a step change in large language model (LLM) capability that the company says will power smarter search, new interactive interfaces and a fresh wave of developer tools.
“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,” Sundar Pichai, CEO of Google and Alphabet, wrote in a post on X.
The announcement brings together advances in reasoning, multimodal understanding, agentic coding and something Google calls generative UI, all packaged for consumers, developers and enterprise customers.
Pichai cast the launch as the continuation of a major long term push. He says Gemini began “nearly two years ago” and called it “one of our biggest scientific and product endeavours ever undertaken as a company”.
He describes Gemini 3 as the next step in a progression. Gemini 1 expanded multimodality and context length, while Gemini 2 laid the groundwork for agentic behaviour and improved reasoning, culminating in Gemini 2.5 Pro holding the top spot on LMArena for months.
A stronger, broader model
Gemini 3 is being positioned as Google’s most capable model so far. It is available across the Gemini app and AI Mode in Search for paying subscribers and is being offered to enterprises through Vertex AI and Gemini Enterprise.
Developers can access the model via the Gemini API and Google AI Studio, while Google has also introduced a new agentic development platform called Antigravity to showcase agent-led workflows.
Researchers from Google have published the ideas behind generative UI and shown how models can assemble not only text but whole interactive experiences on the fly.
According to Google, Gemini 3 is faster at complex reasoning, stronger at handling images and video, and better at translating high level instructions into code and interfaces.
Google’s own materials show Gemini 3 Pro topping multiple benchmarks and demonstrating improvements in areas that matter for real world use. The model scores highly on multimodal tests, on long context tasks and on coding benchmarks measuring how well a model can follow complex, multi step instructions.
The tech firm also highlights practical features for users such as dynamic visual layouts in Search and a redesigned Gemini app that stores people’s creations in a My Stuff folder and offers experiments named visual layout and dynamic view.
Search and generative UI advances
The update is engineered to change how software is built. Logan Kilpatrick, product lead for Google AI Studio and the Gemini API, notes that Gemini 3 can assist both seasoned engineers and what Google calls vibe coders.
Kilpatrick states, “Whether you are an experienced developer or a vibe coder, Gemini 3 can help you bring any idea to life.” He explains that the model is being integrated into tools and IDEs to speed prototyping and automation.
The developer blog explains that Gemini 3 brings agentic coding abilities and a one million token context window that allows it to analyse entire code bases and orchestrate multi step development tasks.
Search and research teams are emphasising a different, but related benefit. Elizabeth Hamon Reid, vice president of engineering for Search, describes how Gemini 3’s reasoning is helping create more interactive and actionable search results.
Reid says “Gemini 3’s state of the art reasoning grasps depth and nuance, and unlocks new generative UI experiences with dynamic visual layouts, interactive tools and simulations tailored specifically for your query.”
She points out that this is the first time a Gemini model has been shipped in Search on day one.
The practical result promises more than a text answer. For complex queries users may see tailored simulations and tools that let them explore a subject rather than just read about it.
Generative UI is the research thread that links the product ambitions. Google researchers explain that a generative UI implementation makes the model produce not just content but a whole customised interface for a given prompt.
The research team says generative UI can create pages, games, calculators and simulations on the fly and that, in human preference tests, their generated interfaces came close to expert made pages when generation time was not considered.
The paper and project page underlying this work are highlighted as the foundation for experiments coming to the Gemini app and Search.
Enterprises are being invited to adopt the same capabilities with a sales pitch that stresses practical outcomes.
Saurabh Tiwary, vice president and general manager, Cloud AI, notes that Gemini 3 is available on Vertex AI and Gemini Enterprise and is suitable for tasks ranging from image and video analysis to contract review and supply chain adjustments.
Safety checks
Google explicitly says Gemini 3 is its most secure model yet and that it has been subject to what it describes as a comprehensive set of safety evaluations. The company highlights improvements in areas such as resistance to prompt injection and reductions in sycophancy, while also acknowledging that generative UI can be slow and may sometimes produce inaccuracies that will need polishing.
The company has rolled out Gemini 3 features first to paying subscriber tiers and to enterprise customers via Vertex AI. It is offering developer previews of APIs and tools while framing generative UI and Antigravity as experiments.
Earlier this month, ChatGPT maker OpenAI introduced a significant update to its large language models with the release of the GPT-5.1 series, comprising GPT-5.1 Instant and GPT-5.1 Thinking. Anthropic released Claude Sonnet 4.5 in September 2025, with large leaps in reasoning, math and coding performance, extended autonomous task horizons, and top-tier agentic/computer-use abilities.
