Google has officially rolls out Gemini 3, its most powerful and intelligent AI model yet, marking a major leap in reasoning, multimodal understanding, and agent-based coding. The new model rolled out on Nov 18, 2025 across the Gemini app, Google Search (AI Mode), and for developers in Google AI Studio and Vertex AI.

Key Improvements in Gemini 3

• Stronger Reasoning & Benchmark Performance
  Google says Gemini 3 Pro significantly outperforms its predecessor, Gemini 2.5 Pro, on a variety of major AI benchmarks.  In internal testing, it scored a record 1,501 Elo on the LMArena leaderboard and demonstrated advanced reasoning abilities in topics like mathematics and problem-solving.

• Multimodal Understanding
  Unlike many models that bolt on vision or audio, Gemini 3 was trained natively on text, images, video, and audio, enabling richer multimodal interactions.  It can generate visually structured responses — like magazine-style layouts, interactive tables, and dynamic charts — thanks to its “generative interfaces” feature.

• New Deep Think Mode
  Google is introducing a variant called Gemini 3 Deep Think, which is designed for highly complex reasoning tasks. Though not yet widely available, it’s being tested for use by Google AI Ultra subscribers.

• Coding & Agentic Capabilities
  Gemini 3 excels at “vibe coding” — meaning you can describe your intent, and the model turns that into functional code.  To support this, Google has launched Google Antigravity, an “agent-first” development platform where AI agents can independently write, test, and execute code using the editor, terminal, and browser.
