What is Gemini 3 Pro? The most important basics of the new Google model
Gemini 3 Pro is Google’s revolutionary AI model for 2025, topping the LMArena leaderboard with 1501 Elo points and setting a whole new benchmark in multimodal AI performance.
Technical basics and architecture
The model is based on a mixture-of-experts architecture that only activates the parts relevant to a task. This makes it extremely efficient, even for the most complex queries.
The 1 million token context window is particularly impressive – this corresponds to around 750,000 words or several hours of video files. Imagine being able to keep an entire book, a presentation and an hour-long meeting video in your head at the same time and draw conclusions from them.
Native multimodality processes all media types simultaneously:
Text documents and code repositories
Images and complex graphics
Audio files and conversations
Hour-long videos with complete analysis
💡 Tip: The context window works like a superhuman working memory – while humans can only process 7±2 units of information at the same time, Gemini 3 Pro keeps an eye on a million contexts.
Differentiation from Gemini 2.5 Pro and other models
The leaps in performance are measurably dramatic. In Humanity’s Last Exam, Gemini 3 Pro achieves 37.5 percent (Deep Think mode: 41 percent) – well ahead of GPT-4o and Claude.
Benchmark comparison of the top models:
Gemini 3 Pro: 1501 Elo points, 91.9 percent on GPQA Diamond
GPT-4o: Significantly lower reasoning values
Claude 3.5 Sonnet: Strong text performance, but weaker multimodality
The OmniDoc 1.5 benchmark shows Gemini 3 Pro’s superiority in document comprehension: With only 0.115 edit distance, it interprets tables, graphics and even handwriting more precisely than all competitors.
Gemini 3 Pro redefines AI standards by combining true understanding of different media types with exceptional reasoning ability – a combination that was previously unattainable.
Deep Think mode: Google’s answer to complex reasoning
Deep Think mode revolutionizes how AI solves difficult problems – instead of lightning-fast but superficial answers, Gemini 3 Pro deliberately takes time for thoughtful problem-solving steps.
How does Deep Think work?
Deep Think is automatically activated when complex queries arise and thinks through problems step by step like a human. The system recognizes mathematical tasks, scientific questions or strategic challenges and then switches to analysis mode.
The leap in performance is measurable: in Humanity’s Last Exam, the success rate rises from 37.5% to 41% – a quantum leap in AI development.
The technology behind it: Instead of answering immediately, the system breaks down complex problems into sub-steps, checks intermediate results and corrects itself.
Practical use cases for Deep Think
Scientific calculations: Formula evaluations, data analyses and hypothesis tests are carried out more precisely than with standard modes.
Strategic business decisions: Market analyses, competitor evaluations and investment decisions benefit from the thoughtful approach.
Complex data evaluations: Large data sets are systematically analyzed, patterns are recognized and conclusions are logically derived.
💡 Tip: Deep Think is usually activated automatically. However, you can also request it explicitly: “Analyze this data step by step” or “Think through this strategy systematically”.
Copy & paste prompt for market analysis:
Systematically analyze the market for [your product/service]:
1. Target audience segmentation with data
2. Evaluate the competitive landscape
3. Calculate market potential
4. Derive strategic recommendations
Use Deep Think for every step of the analysis.
The Deep Think mode turns Gemini 3 Pro into a digital strategy consultant that not only thinks quickly, but above all correctly.
Agentic capabilities: When AI works independently
Gemini 3 Pro revolutionizes the use of AI through true agentic capabilities – this means that the AI works independently on complex tasks over several steps instead of just reacting to individual prompts.
What are agentic AI functions?
Agentic AI plans, executes and corrects itself during multi-step workflows. Unlike traditional chatbots that only react, Gemini 3 Pro develops independent strategies to solve problems.
In concrete terms, this means that you specify a goal and the AI develops a plan, works through it step by step and adapts its approach if obstacles arise. These features are currently only available to Gemini Ultra subscribers after an additional security check.
Practical agent workflows in marketing
Agentic capabilities really come into their own with complex business processes:
Email management: sorting inboxes by priority, preparing responses and scheduling follow-ups
Project structuring: planning software development independently from requirements analysis to documentation
Data analysis: linking multiple data sources, identifying anomalies and creating automated reports
Content production: from target group analysis and concept creation to final implementation
Safety with autonomous AI use
💡 Tip: Agentic AI is never recommended to work unsupervised on business-critical decisions. Define clear boundaries, monitor intermediate results and maintain final control over important workflows.
The Terminal Bench 2.0 success rate of 54.2 percent shows this: Gemini 3 Pro already enables complex, multi-step computer tasks to be solved independently – a milestone for practical AI applications in companies.
Multimodal superpowers: all media types in one system
Gemini 3 Pro revolutionizes the way you work with different media formats – processing, understanding and analyzing everything simultaneously in a single system.
Native processing of different file formats
The 1 million token context window makes it possible: you upload complete video files of several hours and have them analyzed in terms of content. At the same time, Gemini 3 Pro analyzes your texts, screenshots and audio files.
Particularly practical for developers: entire code repositories are understood at once. This means you can upload a complete software structure and have it explained to you how everything works together – without splitting up individual files.
OCR and document understanding
The OmniDoc 1.5 benchmark shows the precision: with just 0.115 edit distance, Gemini 3 Pro achieves industry-best values for text recognition. This clearly outperforms all competitor models.
PDF documents with complex tables, diagrams and different fonts? No longer a problem. Even handwritten notes are reliably digitized and can be processed directly.
Mini-FAQ: Multimodal processing
Which file formats are supported?
Text, PDF, images (JPG, PNG, WebP), audio (MP3, WAV), video (MP4, MOV) and code files in all common programming languages.
Are there any size restrictions?
Individual videos up to several hours in length are possible. The context window of 1 million tokens corresponds to around 750,000 words.
How accurate is the image-to-text conversion?
With 0.115 edit distance in the OmniDoc benchmark, the error rate is less than 12 percent – even with complex document layouts.
💡 Tip: Upload different media types on one topic at the same time – Gemini 3 Pro automatically recognizes connections between video content, presentation slides and text documents.
This multimodal super intelligence saves you hours when sorting and evaluating different file formats – everything happens in a single analysis step.
