- Gemini 3 Pro improves reasoning, multimodality, and context window up to 1M tokens.
- It integrates into the AI Search Mode with model selection and generates interactive interfaces.
- It promotes AI agents and the new Google Antigravity platform aimed at developers.
- Gradual rollout: available in the Gemini app in 30 languages; advanced features require paid plans.
Google's latest AI bet is here: Gemini 3 Pro It arrives as the most ambitious model from the company.with clear progress in reasoning, vision, and execution of complex tasks. The company It promises fewer steps to reach useful answers and greater accuracy in demanding queries.without abandoning its security approach.
Beyond the headline, the move has practical implications: the system It is deployed in consumer and developer products, with a presence in the Gemini app, the API, and the Google cloud. Locally, Spain and Europe They receive support from day one. through the application, available in Spanish, Catalan, Basque and Galician, while the The search engine with AI Mode progresses in phases.
What does Gemini 3 Pro offer compared to previous generations?
According to Google, the evolution from Gemini 1 and 2 translates into a leap in reasoning, understanding of context, and multimodal capabilitiesThe idea is that the system interprets nuances, grasps the intention, and asks for fewer clarifications, so that the user gets to what they need faster.
The new model reduces verbiage, prioritizes more direct answers It minimizes clichés while improving "deep thinking" on complex problems, code execution, and visual analysis. All of this is supported by a broader context and better handling of long-form data.
Google is focusing on a series of improvements that impact the daily and professional use of the model. Among them, the following stand out:
- Generation of interactive visual elements (simulations, calculators, real-time widgets) integrated into the search engine results.
- Parallel reasoning between text and visual elements for interpretation tables, diagrams and interfaces with more accuracy.
- Expanded context window up to 1 million tokens to work lengthy documents, code repositories, or long videos.
- Programming improvements: generation and validation of more reliable code, as well as creation of rich web interfaces.
- Enhanced agentic capabilities: planning and execution of complex tasks under human supervision.
One practical new feature is that, in some queries, the answer may be a small interactive web app that the model itself generates on the fly, designed to learn, compare options, or make decisions with structured data.
Performance and benchmarks
In third-party tests and internal benchmarks, Gemini 3 Pro scores remarkable peaks. LMArena leads with 1.501 ELO, surpassing the previous record of 2.5 Pro. In academic reasoning, He scored 37,5% in Humanity's Last Exam and 91,9% in GPQA Diamond, while in mathematics it reaches a 23,4% on MathArena Apex.
In multimodality, It shows improvement in tests such as MMMU-Pro (81%) and Video-MMMU (87,2%), and demonstrates progress in factual accuracy with SimpleQA Verified (72,1%). Although comparisons with rivals (OpenAI or Anthropic) are favorable, the recommendation to interpret these results as a guide and not as an absolute truth for all use cases.
Multimodality and expanded context window
El The differentiating value of Gemini 3 Pro lies in its ability to understand text, images, audio and video together and reason with themThis multimodal reading helps, for example, to break down a sports technique video or to synthesize academic research with visual aids.
The context window of 1 million tokens It allows uploading from code repositories to complete manuals or video lessonsand request summaries, visualizations, or interactive cards, and facilitates scenarios of Local AIIt also facilitates tasks such as unifying handwritten notes (recipes or notes) and transforming them into shareable material.
AI Agents and Google Antigravity
Gemini 3 Pro reinforces the shift towards agentic AI: It's not limited to responding; it can also execute multi-step workflows.In Google's chatbot, Gemini Agent (AI Ultra subscribers) appears to classify Gmail, plan trips, or execute chained actions with human control.
For developers, Google launches Antigravitya whirlpool bath, platform where agents control editor, terminal and browserThe promise: to plan and complete end-to-end software tasks, write features, pass tests, debug and validate code. all within the same environment.
Antigravity integrates other models from the family (such as 2.5 for computer use and the Nano Banana image generator) and It aims to help programmers move from "writing code" to defining objectives.delegating the rest to the agent when it is reasonable to do so.
AI Mode in Search: How it's integrated and what changes
For the first time, a model of this magnitude arrives at AI Search Mode From day one. The search engine includes a model selector: a faster default one and Gemini 3 Pro for particularly complex queries.
In this mode, AI doesn't just return text: it can generate interactive templates and interfaces that help to study, simulate scenarios or calculate financial options with the user's parameters.
Regional availability: Google is rolling out AI Mode with model selection gradually. In Spain and the rest of Europe, access to the most advanced features It may take time to align with the US and, in some cases, require AI Pro or AI Ultra plans.
Safety and external assessments
Google claims that Gemini 3 is its most secure model to date, with less hype. greater resistance to prompt injections and better defenses against misuse, especially in sensitive areas such as cybersecurity and for protect your privacy.
In addition to internal work with its Frontier Safety Framework, the company has involved third parties such as the UK's AISI and specialist firms (Apollo, Vaultis and Dreadnode) to audit risks before rolling out the new capabilities on a large scale and advising on how protect your pc.
Availability, languages and plans in Spain and Europe
Gemini 3 Pro is available in the Gemini app and in the developer API (AI Studio, Vertex AI, and CLI), with support for 30 new languages, including Spanish, Catalan, Basque, and Galician. AI Search Mode will be rolled out in phases, and the advanced model is not the default option.
Gemini 3 Deep Think, the enhanced reasoning mode, will be released later. additional security testsInitially for AI Ultra subscribers. For enterprises, integration is available through Vertex AI and Gemini Enterprise. Some educational promotions announced for the US do not yet have this feature. confirmed equivalent in Europe.
Gemini 3 Pro combines more robust reasoning, multimodal reading, and practical agents that perform real-world tasks. It's already available for testing in Spain and Europe through the app and the developer ecosystem, while the AI-powered search engine will continue to gain traction. advanced capabilities as regional deployment and subscription plans allow.
