Gemini 3 is Google DeepMind’s new flagship model built for stronger reasoning, sharper accuracy, and full multimodal understanding. It beats Gemini 2.5 Pro across every major benchmark, delivers PhD-level problem solving, and sets new records in math, science, and factual QA.

It also shows major gains in image and video reasoning, making it a reliable tool for complex tasks.

Google is rolling out Gemini 3 Pro in preview across its products starting today. The release also includes Gemini 3 Deep Think, an advanced reasoning mode now in testing.

Google released Antigravity, a new coding environment where the AI doesn’t sit on the side, it controls the workspace. It can read your code, plan tasks, write new code, test it, and fix issues with far less human input.

Powered by Gemini 3, the system uses advanced reasoning and agentic tools to execute software tasks end-to-end and validate its own output.

The public preview is free. Supports Gemini 3 Pro, Claude Sonnet 4.5, and GPT-OSS as model options.

ChatGPT for Teachers is a new secure workspace for U.S. K–12 educators. It lets teachers handle classroom materials and student information safely and is free for verified educators through June 2027.

Meta has launched SAM 3D, a new system that gives common-sense 3D understanding to everyday images.

It includes two models: SAM 3D Objects for rebuilding scenes and objects, and SAM 3D Body for estimating human pose and shape.

Both models turn 2D images into accurate 3D reconstructions with state-of-the-art results.

xAI has introduced Grok 4.1 Fast, its fastest and most capable tool-calling model.

It has a 2M-token context window and is built for real-world tasks like customer support and deep research. The release also includes the Agent Tools API. Developers can let Grok browse the web, search X posts, run code, and pull documents with simple integration.

Grok 4.1 Fast is trained for long multi-turn workflows and excels in real-time retrieval and agentic search.

MagicPath has launched Sketchpad, an AI tool that turns hand-drawn wireframes into interactive prototypes.

Designers can move from rough ideas to working interfaces without writing code.

Sketchpad supports free-draw shapes, design system styling, keyboard shortcuts, mixed sketches and components, and image references. It produces ready-to-share prototypes that work on mobile devices.
