🗞️ AI News of The Week: Gemini 3

Mike’s Take:
I am a big fan of Gemini and at first glance, Gemini 3.0 Pro seems to be worth the hype as it just feels smart and powerful. Try in Gemini or AI Studio

Google has introduced Gemini 3, its most intelligent model, which combines all previous capabilities to help users "bring any idea to life" and is rolling out across Google products starting today. It features state-of-the-art reasoning, multimodal understanding, and is available in a more powerful Deep Think mode for complex problems.

Key highlights of Gemini 3:

  • It significantly outperforms Gemini 2.5 Pro on major AI benchmarks for reasoning and multimodal understanding.

  • It introduces Deep Think mode for a step-change in performance on challenging benchmarks like Humanity’s Last Exam.

  • It supports a 1 million-token context window and advanced multilingual performance for the "Learn anything" objective.

  • It is the best "vibe coding" and agentic coding model yet, boosting developer productivity in platforms like the new Google Antigravity.

  • It demonstrates better long-horizon planning to help with complex, multi-step workflows like organizing an inbox or booking services.


🧠 AI Term of The Week: ReRanking (in RAG)

ReRanking is the secret weapon in RAG Pipelines that helps AI choose the best answers, not just the first ones it finds.

When AI retrieves multiple documents or snippets, a reranker scores and sorts them by how relevant they are to your question or prompt. This means more accurate, helpful, and context-aware responses.

Why it matters for RAG creators:

  • Better quality content from your custom AI tools

  • Less “hallucination” and fluff in AI outputs

  • Smarter chatbots, research assistants, and knowledge workflows

  • Can boost performance of personal knowledge bases and GPTs

AI Tool Used for Reranking:
Cohere

🧰 AI Tool of The Week: Antigravity by Google

Google Antigravity is an agent-first Integrated Development Environment (IDE) that leverages AI to evolve the traditional coding platform like VS Code into an agent-centric experience.

TLDR: Google Antigravity is a standalone coding/vibe-coding app by Google.

What is an IDE?

An IDE, or Integrated Development Environment, is a software application for developers to build apps.

Key features:

  • Source code editor: For writing and editing code.

  • Build automation tools: For compiling, interpreting, or transforming source code into executable computer programs.

  • Debugger: For testing and finding errors in the code.

In essence, an IDE provides the framework where developers write, test, and package their applications.
