Gemini 3 Pro is Google’s most advanced AI model. It is designed to handle complex tasks that require advanced reasoning and understanding of different types of data. It is currently available in preview for developers and through the Google AI Pro plan.

Key features and capabilities:

Complex tasks: Gemini 3 Pro is optimized for complex tasks that require broad general knowledge and advanced reasoning across various data types, such as text, images, and video.
Creative generation: The model excels at creative writing and developing complex, multifaceted concepts.
Advanced reasoning: It is considered the most intelligent Google model to date, with improved logical reasoning, analysis, and coding capabilities.
Research assistance: It assists users in summarizing hours of work into minutes by providing detailed reports on topics by analyzing hundreds of web pages in real-time.
Multimodality: It has advanced visual and spatial reasoning capabilities (such as the Gemini 3 Pro Image model).

Availability:

Gemini 3 Pro is currently in preview and is available through:

Gemini API: Developers can access the model through the Google AI Studio and Vertex AI platforms to build applications.
Google AI Pro subscription: Users who subscribe to the Google AI Pro plan get extended access to Gemini 3 Pro features, including the “Deep Research” feature.

The model was launched in November 2025. Demand was so high that Google had to temporarily adjust the system to ensure availability. Pricing is calculated per million tokens, and details are available on the API pricing page.

Jules is Google’s autonomous, asynchronous AI coding agent designed to help software developers automate complex tasks like fixing bugs, writing tests, and implementing new features.

Unlike traditional “co-pilots” that suggest code as you type, Jules acts like an independent collaborator that clones your codebase into a secure virtual machine (VM) to perform work in the background.

Key Capabilities and Features (2025 Updates)

Autonomous Workflow: Tasks are submitted via prompt, and Jules plans, executes, and verifies the changes independently, eventually opening a pull request.
Asynchronous Development: Developers can assign tasks to Jules and continue working on other projects while it runs in a cloud environment.
Gemini-Powered Intelligence: As of late 2025, Jules utilizes advanced models like Gemini 2.5 Pro and has been updated with integrations for Gemini 3 for improved reasoning and transparency.
Critic-Augmented Generation: A “critic” feature provides an adversarial review of Jules’ proposed changes before completion to ensure high code quality.
Proactive Assistance: A new Suggested Tasks feature automatically scans code to propose improvements or schedule routine updates without being prompted.
Audio Changelogs: It can generate audible summaries of recent commits to help developers catch up on project history.

How to Use Jules

Web Interface: You can sign in and manage repositories at jules.google.com.
Command Line (CLI): Use Jules Tools to interact with the agent directly from your terminal, allowing for parallel task runs and local diff viewing.
Jules API: Developers can programmatically integrate Jules into custom workflows, CI/CD pipelines, or tools like Slack and Linear.
GitHub Integration: Tasks can be assigned directly by adding a jules label to an issue in a connected GitHub repository.

Pricing and Availability

Jules is currently in Public Beta. It is available globally where Gemini is supported and offers structured tiers:

Free Tier: Accessible to all users for basic exploration.
Paid Tiers: Higher usage limits are available via Google AI Pro and Ultra subscriptions.

In 2025, “Google Antigravity” primarily refers to a professional software development platform, though it can also refer to a classic search engine Easter egg.

1. Google Antigravity (Agentic IDE)

Launched on November 18, 2025, Google Antigravity is an “agent-first” AI-powered Integrated Development Environment (IDE). Antigravity uses autonomous agents to plan, execute, and verify entire development tasks. Standard coding assistants suggest code snippets.

Key Components:
- Agent Manager: This is an interface for orchestrating multiple background agents. The agents work across different workspaces.
- Editor View: This is a fully-featured IDE (forked from Visual Studio Code) for coding with AI-powered tab completion and inline commands.
- Antigravity Browser: This browser allows agents to navigate, test, and verify web applications.
Core Features:
- Artifacts: Agents produce deliverables like implementation plans, code diffs, and browser recordings. These allow for easy verification.
- Model Optionality: It is powered primarily by Gemini 3, but also supports other models. These include Anthropic’s Claude Sonnet 4.5 and OpenAI’s GPT-OSS.
- Feedback Loops: Users can leave comments directly on artifacts to guide agent iteration. This is similar to “Google Docs-style” comments.
Availability: It is currently in Public Preview for individual users with personal Gmail accounts. There is no charge. Higher rate limits are available for Google AI Pro and Ultra subscribers.

2. Google Antigravity (Easter Egg)

This web trick mimics the lack of gravity on the Google search page. It is often hosted by third-party sites like Mr. Doob.

How to trigger: Searching “Google Gravity” or “Google Antigravity” and clicking “I’m Feeling Lucky” typically causes the search bar and buttons to fall to the bottom of the screen or float around.
Interaction: Users can click and “throw” the various page elements across the screen.

google antigravity vs google jules

In 2025, Google offers two distinct agentic coding tools:

Antigravity and Jules. Both use Gemini 3 models for coding automation, but they differ in their environment and interaction style.

Quick Comparison (2025)

Feature	Google Antigravity	Google Jules
Primary Format	Standalone AI-first IDE (fork of VS Code)	Background/Asynchronous Coding Agent
User Interaction	Synchronous/Interactive: Code alongside agents in real-time.	Asynchronous: Assign a task and return later.
Integration	Local environment; works like Cursor or Windsurf.	Integrated with GitHub repositories and works in a cloud VM.
Best For	Active development, “vibe coding,” and multi-agent orchestration.	Routine maintenance, bug fixing, and long-running documentation tasks.

Google Antigravity: The AI-First IDE

Launched in November 2025, Antigravity is an “agent-first” development platform designed as a direct competitor to Cursor.

Key Strength: Orchestration. It allows multiple agent threads to run simultaneously, such as one agent refactoring a file while another writes unit tests.
Browser Control: It integrates Chrome, allowing agents to “see” rendered HTML, click buttons, and run front-end tests autonomously.
Status: Currently in public preview; it supports Gemini 3 Pro and Claude 3.5 models.

Google Jules: The Asynchronous Agent

Jules is a specialist “subcontractor” that handles bounded tasks in the background.

Key Strength: Autonomy. Jules runs in a secure cloud environment (VM), meaning it can work on a task for hours without requiring the user’s session to stay active.
GitHub Focused: It is primarily used to open branches, fix GitHub issues, and submit pull requests automatically.
Availability: Now out of beta and available via Jules.google or as a VS Code extension.

Pricing & Access

Both tools are part of the Google AI Pro/Ultra plans (typically bundled with Google One subscriptions):

Jules: Offers a free tier; paid tiers provide higher concurrency (e.g., 15 tasks at once).
Antigravity: Available for free during its initial launch period, with premium rate limits tied to the Google AI Pro plan.
