# Google Antigravity - Enterprise Compatibility Evaluation

## Overview
Google Antigravity is an AI-powered agentic IDE (Integrated Development Environment) launched in November 2025 alongside Gemini 3. Built as a modified fork of Visual Studio Code, it features an "agent-first" design where AI agents can autonomously make changes, run code, and verify their work. The platform is powered by Gemini 3 Pro, Gemini 3 Deep Think, and Gemini 3 Flash models.

## Enterprise/Commercial Use Permission

**Status: YES - Permitted (Currently in Public Preview)**

Google Antigravity permits commercial use, with Team and Enterprise plans anticipated in 2026. Currently available as a free Public Preview with rate limits.

**Key Points:**
- Public Preview is free for all developers
- Code generated by agents belongs to the user
- Team and Enterprise plans coming 2026
- Google does not guarantee generated code is free from third-party rights

## Data Training Policies

### Public Preview (Free Tier)

**Status: AMBIGUOUS - CAUTION ADVISED**

**Current State:**
- "Telemetry" toggle available but doesn't prevent code transmission
- AI inference must happen in cloud - code is transmitted
- Language around "product improvement" is ambiguous
- **No zero-retention guarantee** during Preview

**Key Concerns:**
> "The Preview offers no zero-retention guarantee, and code could be used for training."
> "Disabling 'Telemetry' doesn't prevent code transmission—AI inference must happen in the cloud."

### Google AI Pro/Ultra Subscribers

**Better Protections:**
> "For Team tiers: Your code snippets are not used to train Google's public models. This is non-negotiable for commercial work."

### Anticipated Enterprise Tier

**Expected Features:**
- No training on customer code
- Data residency options
- Enhanced privacy controls
- SSO and admin controls

**Sources:**

- https://cension.ai/blog/google-antigravity-ai-what-is-it/

---

## Data Retention and Sharing Policies

**Current (Public Preview):**
- No published zero-retention policy
- Data retained according to Google Antigravity Privacy Policy
- Users may request data export within 30 days of termination

**Anticipated Enterprise:**
- Google Workspace enterprise customers typically get:
  - Enterprise-grade security and compliance
  - Data remains private
  - No sharing with third parties for training

**Data Location:**
- Processed within Google Cloud infrastructure
- Enterprise may have data residency options

**Important Limitation:**
> "There's no SOC 2 report yet; Google promises compliance at GA, but currently lacks IP indemnification and zero-retention guarantees."

---

## IP and Confidentiality Concerns

**Intellectual Property:**
- **Code Ownership**: Users own generated code
- **No Guarantee**: Google does not guarantee code is free from third-party rights
- **User Responsibility**: Users responsible for license compliance

**Confidentiality Risks:**

**Security Warnings in Terms of Service:**
> "Security is an issue, and the terms of use warn that 'Antigravity is known to have certain security limitations.' Risks identified include data exfiltration and code execution."

**Agent Access Concerns:**
> "By default, Antigravity agents have autonomous access to your terminal, filesystem, and network connections."

**Execution Modes:**
1. **Automatic execution**: Agents run all commands without approval
2. **Agent-assisted** (default): AI decides when to ask for approval
3. **Require approval**: Every command needs human authorization

**Recommendation for Enterprise:**
> "For clients in regulated industries (Healthcare, Finance), Antigravity should be treated as a public cloud environment. Do not use it for codebases containing PII or hardcoded secrets until a formal BAA covers the tool."

**Compliance Status:**
- No SOC 2 report yet (promised at GA)
- No IP indemnification currently
- Google Cloud infrastructure (inherits some certifications)

---

## Gemini Quota Relationship

### Key Question: Are Antigravity and Gemini Limits Shared?

**Finding: PARTIALLY SHARED / COMPLEX**

**Evidence:**
> "The quota for Gemini 2.5 Pro got merged with the quota for Gemini 3 Pro, creating a single shared quota for both models - if 50% is used with Gemini 3 Pro, only 50% remains for both models."

**Separate Systems:**
- Antigravity uses "work done" based limits (task complexity)
- Gemini app uses prompt-based limits
- Gemini Code Assist agent mode and CLI quotas are combined

**Rate Limit Refresh:**
| Tier | Antigravity Refresh | Gemini App |
|------|-------------------|------------|
| Free | Weekly | Daily |
| AI Pro | Every 5 hours | Higher daily |
| AI Ultra | Every 5 hours (highest) | Highest daily |

**Bottom Line:**
- Google AI Pro/Ultra subscription improves both Antigravity AND Gemini limits
- Quotas appear to be tracked separately but subscription tier affects both
- Heavy Antigravity usage does NOT appear to drain Gemini app quota directly
- However, some model-level quotas (Gemini 3 Pro) may be shared across products

## Free Tier Details

**Public Preview (Free)**

**Features Included:**
- Full Antigravity IDE access

| Team | TBD | SSO, admin controls |
| Enterprise | ~$40-60/user/month | Data residency, compliance |

**Pricing Model Shift:**
> "We are no longer paying for 'code completion.' We are paying for 'autonomous hours.'"

**Compute Credits:**
- Intensive tasks may require additional "High-Density Compute Credits"
- Similar to Claude's usage-based approach

---

## Usage Limits

### How Limits Work:
> "Google Antigravity usage limits aren't calculated by the number of requests or lines of code written. Instead, the rate limits are based on 'work done' by Antigravity's AI agent."

### Rate Limit Details:
- **Simple tasks**: Lower quota consumption
- **Complex reasoning/refactoring**: Higher quota consumption
- **Multi-file operations**: Highest consumption

### Refresh Cycles:
- **Free**: Weekly refresh
- **AI Pro/Ultra**: 5-hour refresh

### Known Issues:
- Some users report 4-7 day lockouts due to bugs
- Cannot query remaining quota directly from agent
- EU region users may experience lower quotas

---

## Summary Recommendation

### Current Assessment (Public Preview):

**Strengths:**
- Powerful agentic AI development capabilities
- Free during preview period
- Manager view for multi-agent workflows
- Built on proven Gemini 3 models
- Google Cloud infrastructure

**Critical Concerns:**
- **No SOC 2 certification yet**
- **No zero-retention guarantee**
- **Code may be used for training (unclear policy)**
- **Security limitations acknowledged in ToS**
- **No IP indemnification**
- **Autonomous agent access to filesystem/terminal**

### Recommendation Matrix:

| Use Case | Recommendation | Reason |
|----------|---------------|--------|
| Personal projects | ✅ OK to use | Low risk, free |
| Learning/experimentation | ✅ OK to use | No sensitive data |
| New hackathon projects | ⚠️ Use with caution | No existing IP at risk |
| Enterprise codebase | 🚨 NOT RECOMMENDED | No compliance guarantees |
| Regulated industry | 🚨 DO NOT USE | No BAA, no SOC 2 |
| Sensitive/classified code | 🚨 DO NOT USE | Security limitations |

### For Enterprise Adoption:

**Wait for GA Release (2026) when Google provides:**
- [ ] SOC 2 Type II certification
- [ ] Zero data retention option
- [ ] Clear no-training policy
- [ ] IP indemnification
- [ ] BAA for healthcare
- [ ] Enterprise terms of service

**Current Alternative:** Use **Google Gemini Code Assist** (Standard/Enterprise) which has established enterprise protections, or **Continue.dev** for air-gapped requirements.
