Google's latest AI model, Gemini 3, has arrived, poised to challenge OpenAI's ChatGPT and other leading generative AI systems. Released on November 18, 2025, Gemini 3 is Google's most intelligent AI model to date, boasting enhanced reasoning and multimodal capabilities. It is designed to understand the intent and nuance behind user requests with greater accuracy.

Key Features and Capabilities

Gemini 3 showcases significant advancements across various domains:

• Multimodal Understanding: Gemini 3 processes text, images, audio, video, and code within a single transformer stack, enabling genuine cross-modal reasoning. This allows the model to interpret a sketch and generate working code, or analyze a video and explain its scientific concepts.
• Reasoning and Problem-Solving: Gemini 3 Pro demonstrates PhD-level reasoning and outperforms previous models in reasoning, multimodality, and coding benchmarks. It achieves top scores on benchmarks like Humanity's Last Exam and GPQA Diamond.
• Agentic Capabilities: Gemini 3 excels in agentic coding, making Google products more autonomous and boosting developer productivity. Its improved tool use and instruction following enable it to handle complex, multi-step workflows, such as booking services or organizing an inbox.
• Vibe Coding: Gemini 3 is Google's best vibe coding model, delivering richer visualizations and deeper interactivity.
• Generative UI: Gemini 3 unlocks new generative UI experiences, creating dynamic visual layouts, interactive tools, and simulations tailored to user queries. For example, when researching mortgages, Gemini 3 can generate a custom calculator to compare terms and savings options.

Availability and Integration

Gemini 3 is now accessible across various Google products and platforms:

• Gemini App: Available to all users in the Gemini app.
• Google Search: Powers AI Mode in Google Search, allowing users to ask nuanced questions in natural language.
• AI Studio and Vertex AI: Developers can build with Gemini 3 in Google AI Studio, Vertex AI, and Gemini CLI.
• AI Overviews: Available in AI Overviews for Pro and Ultra subscribers, generating interactive elements.

Google Antigravity: A New Development Platform

Google has also unveiled Google Antigravity, a new agentic development platform powered by Gemini 3. This platform aims to transform AI assistance into an active partner for developers, enabling them to operate at a higher, task-oriented level. Antigravity provides a dedicated agent interface with autonomous agents that can operate through the code editor, terminal, or browser, building applications from a single prompt and creating progress reports.

Enhanced Control and Customization

Gemini 3 offers developers granular control over cost, latency, and reasoning depth:

• Thinking Level: Adjust the logic depth on a per-request basis, setting it to high for deep planning and complex instruction following, or low for high-throughput tasks.
• Thought Signatures: The model generates encrypted "Thought Signatures" representing its internal reasoning before calling a tool, ensuring reliable multi-step execution without losing context.
• Media Resolution: Control multimodal vision processing with the media_resolution parameter, balancing token usage and detail.

Competition and Future Prospects

Gemini 3's release intensifies the competition in the generative AI arena. Google claims that Gemini 3 Pro outperforms models like the new GPT-5.1 from OpenAI and Claude Sonnet 4.5 from Anthropic on various AI benchmarking leaderboards. With its advanced capabilities and broad integration across Google products, Gemini 3 is well-positioned to be a major player in the future of AI. Google plans to introduce Gemini 3 Deep Think mode for Ultra subscribers soon, pushing the boundaries of intelligence even further.
