Just Launched: Gemini 3 Pro Takes the Lead on Multimodal Reasoning

Advertise with us

Welcome back! Google just moved the center of gravity for agents, models, and developer tools in a single stroke. At the same time, companies are scrambling to manage the agent boom, cities are questioning the cost of all this infrastructure, and researchers are looking for new ways to train models when the old sources run dry. The week reads like a preview of how AI will behave when it becomes part of everyday work rather than something we experiment with on the side.

In today’s Generative AI Newsletter:

• Google launches Gemini 3 Pro with new multimodal depth
• Microsoft unveils Agent 365 for full enterprise oversight
• Communities push back as data center construction slows across states
• World models rise as games become the next training frontier

Latest Developments

Google released Gemini 3 Pro on Nov 18 and rolled it into Search, the Gemini app, AI Studio, Vertex AI, and a new agent platform called Google Antigravity. The model pushes multimodal reasoning, a 1M token context window, and an agentic stack designed to plan and act across tools. Pro is available in preview today. Deep Think is coming to safety testers and Google AI Ultra subscribers soon.

What’s rolling out

Benchmark punch Gemini 3 Pro tops LMArena with 1501 Elo and posts frontier wins on Humanity’s Last Exam and MathArena.
Agent playbook Google Antigravity gives agents editor, terminal, and browser access to build and validate full apps.
Multimodal reach The model reads text, images, video, audio and handles 1,000,000 token contexts.
Rollout and safety Pro is in preview now. Deep Think gets extra safety review before wider release.

Gemini 3 reads deeper and acts wider than its predecessors. The product push is part research feat and part platform move. Expect sharper agent behaviors in search and dev tools. Expect more questions on control and auditing as agents gain autonomy. As Sundar Pichai says, this is a step on the path toward more capable systems. Whether that path is thrilling or worrying will depend on how well Google pairs power with restraint.

Microsoft used Ignite 2025 to debut Agent 365, a unified control system built to track, manage, and secure the wave of AI agents spreading through modern organizations. Companies are already running sales agents, support agents, research agents, and office agents, often built by employees and deployed without oversight. Agent 365 is Microsoft’s answer to this growing sprawl by creating a living map of every agent, every data connection, and every action taken across the company.

What Agent 365 delivers:

Full agent discovery that scans the entire workplace to identify approved and shadow agents across all teams.
Risk-based access rules that restrict what agents can touch, limit sensitive data exposure, and block unsafe behavior.
Security baked into the system through Defender, Entra, and Purview, giving agents the same protections as human staff.
A lineup of managed agents, including an autonomous SDR, Office builders inside Copilot, and new security bots that handle alerts and compliance work.

Microsoft paired the launch with fresh IDC data showing a widening gap between companies that deploy agents across many workflows and those still dabbling. The questions that used to belong to science fiction now land on IT desks: Who trained this agent? Who approved it? Who watched it touching data at 3AM? Microsoft saw those questions coming and built the rulebook before most companies realized they needed one.

A new report shows local resistance to data center construction is no longer a series of isolated skirmishes. It is becoming a coordinated movement. Between late March and June, Data Center Watch found that communities blocked or delayed ninety-eight billion dollars worth of planned data center projects, a larger total than the previous two years combined. The slowdown is hitting states that actively court AI investment, even as residents push back over rising electricity costs, land use, and strained grids.

What the report found:

Mounting project delays: An estimated ninety-eight billion dollars in data center builds were blocked or stalled across a three-month window.
Nationwide organizing: Seventeen states saw active resistance, with fifty-three local groups protesting thirty projects.
High success rate: Two out of every three targeted projects were blocked or delayed.
Political crossover: Lawmakers in Virginia, Minnesota, South Dakota and others are questioning subsidies, grid burden, and local authority.

The backlash is gaining a rhythm that did not exist a year ago. Residents from Indiana to Georgia are swapping playbooks on petitions and hearings. State races are folding data centers into campaign messaging. Tech firms are running ads that highlight jobs and tax revenue while facing communities that say the costs are landing on their monthly bills. As AI scale accelerates, this fight over land, power, and local control may become one of the central stories shaping where the industry can grow next.

AI models could burn through the planet’s supply of written text as soon as 2026. Researchers are already hunting for the next fuel source, and a surprising candidate keeps coming up. Video games offer something text never will: endless worlds where an AI can move, fail, retry, and learn how reality behaves instead of just reading about it.

Here is where the momentum is building

Games as training grounds Simulated worlds give AI infinite practice with movement, physics, strategy, and cause-and-effect.
Rise of world models These systems learn by observing environments and predicting what happens next.
New systems emerging DeepMind’s Sima 2 and World Labs’ Marble push AI into richer, 3D spaces.
LeCun’s new direction Meta’s longtime AI chief is leaving to build his own world-model startup.

If world models keep improving, AI will no longer depend on squeezing meaning out of old text. It will learn by exploring, just like any curious creature dropped into a new landscape. And the twist is poetic. After years of reading us, AI may grow up by playing in worlds we invented.

Google Antigravity is a new agentic development platform that lets developers collaborate with AI agents across the editor, terminal, and browser. It is built on Gemini 3 Pro for reasoning, Gemini 2.5 Computer Use for end-to-end execution, and Nano Banana for image generation. The platform is designed to streamline frontend and full-stack work through autonomous, browser-in-the-loop agents.

Core functions:

• Cross-surface control: Coordinates agents across the editor, terminal, and browser for unified development workflows.
• Task-oriented execution: Handles higher-level tasks rather than single commands, producing artifacts and verification results for users to review.
• Parallel workspaces: Runs multiple agent tasks at the same time across different working environments.
• Natural code interaction: Supports tab autocompletion, natural language coding commands, and context-aware agent assistance.

Try this yourself:

Pick a UI feature you want to build. Ask Antigravity to create the structure, generate the components, and open a preview in the browser. Review how the agent moves between the editor and the browser, how it validates its output, and where you want to guide or refine the process.
