What is Gemini 3? Basic understanding
- Gemini was developed by Google DeepMind as the successor to LaMDA and PaLM 2 and is a multimodal LLM family that can process not only text but also images, audio, and code.
- On November 18, 2025, the Gemini 3 generation was officially unveiled. In addition to the base model, Gemini 3 Pro was released immediately, featuring significant advances in reasoning, multimodality, and tool integration.
- At the same time, Google announced the upcoming DeepThink mode—a variant with enhanced reasoning, longer inference chains, and greater robustness for complex tasks.
Gemini 3 positions itself as an all-in-one AI: whether analyzing texts, interpreting images, understanding long code, or mixing multimodal content—the model is set to play a central role in a wide variety of areas.
Gemini 3 Pro: The “workhorse” for professionals and developers
Why Pro?
- Powerful and versatile: According to Google, Gemini 3 Pro outperforms many other models in a variety of benchmarks, including mathematical tasks, coding, multimodal challenges, and reasoning-intensive scenarios.
- Sophisticated multimodality: Pro can process text, images, video, audio, and code simultaneously, making it ideal for tasks that require combining content across media boundaries.
- Tool integration & vibe coding: Of particular interest to developers, Gemini 3 Pro is integrated into tools that enable code generation, software development assistance, and complex workflows. The official launch was accompanied by a new agentic development environment for programmers.
- Stability & security: Google emphasizes that Gemini 3 has been thoroughly tested for security, tamper resistance, and robustness against erroneous inputs to minimize abuse and hallucinations.
Typical use cases for Gemini 3 Pro
- Software development & coding: Quickly generate prototypes, boilerplate code, code reviews, or multimodal documentation.
- Multimedia and content creation: Analyze images, describe videos, transcribe audio, or mix media—for example, in content marketing or social media.
- Productivity & planning: Process extensive documents, conduct research, structure complex information, and plan projects.
- Research & technical texts: Analyze scientific, technical, or legal content with a high degree of context and a need for combination.
Gemini 3 DeepThink: When simple answers aren’t enough
The announced DeepThink mode aims to achieve a new level of AI interaction:
What makes DeepThink different
- Multi-level, in-depth reasoning: DeepThink is designed to tackle complex problems, abstract logic, and long chains of reasoning — going beyond simple answers.
- Self-checking and validation: In testing, DeepThink scored higher on challenging benchmarks, such as Humanity’s Last Exam (41.0% without tools) and the ARC-AGI-2 benchmark (45.1%).
- Multimodal + long-term inference: DeepThink remains powerful even when combining text, images, video, code, or audio — ideal for interdisciplinary, creative, or research-related tasks.
- Agentic and tool integration: DeepThink expands Gemini’s ability to act as a true “partner” — whether in planning, complex workflows, or software projects.
Who is DeepThink intended for?
- Research & Science: Complex hypotheses, lengthy thought experiments, analysis of large amounts of data or literature, multimodal evaluations.
- Software development for large projects: Design, architecture, multi-stage planning, debugging, documentation.
- Strategic planning & consulting: Scenario analysis, business planning, complex decision-making.
- Education & teaching: Complex problems, creative tasks, multidisciplinary learning with multimodal input processing.
Common features: What all Gemini 3 variants have in common
- Multimodality as a core feature: Text, images, audio, video, code — all versions of Gemini 3 are designed to understand and combine content in different media.
- Integration into the Google ecosystem: Gemini 3 is not available in isolation — Google is integrating it into products such as search engines, apps, developer platforms, and presumably other services in the future.
- Large context scope: All models benefit from a greatly expanded context window — up to 1 million tokens — which enables the processing of long documents, codebases, or large amounts of media.
- Focus on security and reliability: According to Google, Gemini 3, and Pro/DeepThink in particular, have been tested more intensively than previous models to reduce hallucinations, misinformation, and abuse.
Limitations and points of criticism
- DeepThink not yet generally available: The mode is currently undergoing safety testing and will only be released to “Ultra” subscribers at a later date.
- Costs and limits for Pro/DeepThink: Premium versions cost — especially for intensive or commercial use — depending on the plan and API access. However, the free model should be sufficient for many users.
- Typical AI weaknesses remain: Despite high benchmark scores, challenges remain in areas such as fact verification, complex ambiguities, or creative but unclear prompts. External security experts and testing are also emphasized.
- Risks due to multimodality and agentic use: With complex content such as image-text-video mixes or tool integration, the risk of misinterpretation, incorrect correlations, or unintended manipulation increases — especially with less controlled use.
