Google Unveils Gemini 3 and Launches “Antigravity” AI Development Platform
Google has officially launched Gemini 3, its most advanced artificial intelligence model to date, and integrated it immediately into key products — a move that highlights the company’s accelerating push into agent-driven AI.
What Is Gemini 3?
Gemini 3 marks a significant leap in reasoning, multimodal understanding, and agentic capabilities.Google describes it as its “most intelligent model,” designed to understand nuance, context, and intent better than previous generations.
The model brings major improvements in:
- Coding and “vibe coding” — Gemini 3 is better at interpreting user intent and generating code with minimal prompting.
- Tool use and long-horizon planning — It can reason through multi-step tasks and plan ahead more reliably.
- Multimodal comprehension — It handles text, images, and possibly even video or audio more fluently.
Google is rolling out Gemini 3 Pro first, while a more powerful “Deep Think” mode is in the works and will be made available to Google AI Ultra users after additional safety reviews.
Immediate Integration Into Google Search
A defining feature of this launch: Gemini 3 goes live in Google Search from day one. That’s the first time Google has embedded a new AI model directly into its core search product at launch.
- In AI Mode for Search, paying Google AI Pro and Ultra users will get responses generated by Gemini 3 instead of standard web results.
- The Gemini app also receives the new model now, giving users access to its advanced reasoning and interactivity features.
New Features: Gemini Agent & Antigravity
Google introduces two big innovations alongside Gemini 3: Gemini Agent and Antigravity.
- Gemini Agent acts like a personal assistant. It can execute multi-step tasks such as planning travel, managing your inbox, or organizing your schedule.
- Google Antigravity is a brand-new development platform built around Gemini 3 Pro.
- It supports multiple AI agents that interact with your editor, terminal, and browser.
- Agents generate “Artifacts” — task lists, plans, screenshots, and browser recordings — so users can track exactly what the agents are doing.
- Two views define the Antigravity experience:
- Editor View — Like a typical IDE, but with an agent in a side panel.
- Manager View — A “mission control” for spawning, controlling, and observing agents working across different workspaces.
- Agents learn over time too: they retain memory of past tasks and evolve.
- Google ships a demo where an agent builds a flight tracker app, tests it, and validates it via a browser recording.
- Antigravity is available now in public preview on Windows, macOS, and Linux, with free usage for Gemini 3 Pro within generous rate limits.
Safety and Responsible Deployment
Google says Gemini 3 is its most secure model yet.
Key improvements include:
- Reduced “sycophancy” — less tendency to flatter users.
- Better resistance to “prompt injections” — malicious inputs designed to manipulate output.
- Enhanced protections against misuse via cyberattacks.
Google also conducted safety evaluations through its “Frontier Safety Framework” and partnered with external experts and independent organizations for independent testing.
Impact on Google Cloud, Developers, and Enterprises
- Developers can now access Gemini 3 via AI Studio, Vertex AI, and through CLI.
- Enterprise customers will benefit from agentic workflows powered by Gemini 3 in a production environment.
- By embedding Gemini 3 into Search and other monetizable products, Google strengthens its strategy to commercialize AI broadly.
Alphabet Stock & Market Implications
The Gemini 3 launch adds a strong shot in Alphabet’s AI strategy. Investors are watching closely. Gemini’s integration into high-revenue products like Search might deepen Google’s AI monetization.
Still, some analysts warn about an AI investment bubble, noting that excitement around new models must translate into real business value.
Leadership’s Vision
Sundar Pichai, Google and Alphabet CEO, praised Gemini 3 as a defining milestone: “a new era of intelligence.” He underlines Google’s full-stack advantage — from research to tooling — as the reason they can deliver such powerful models fast.
Demis Hassabis (Google DeepMind) and CTO Koray Kavukcuoglu also stress the model’s ability to grasp depth, nuance, and longer-term context, enabling it to build, plan, and reason in a more human-like way.
Risks and Cautions
Not everyone is wholly optimistic:
- Alphabet CEO Pichai warned users not to blindly trust AI. He stressed that AI tools, including Gemini, may produce errors and must be used carefully alongside human judgment.
- The rapid business push might pressure safety and robustness. Some fear that in the race to monetize, risks could grow.
What’s Next?
- Deep Think mode, Gemini 3’s most advanced reasoning variant, will roll out soon after further safety evaluation.
- Google promises more models in the Gemini 3 series over time.
- Feedback from developers and enterprises will shape future updates.
- Google aims to expand Antigravity’s capabilities, making agentic development more central for its AI ecosystem.
