Maximizing Antigravity AI Credits: March 2026 Pricing Edition

March 2026 brought significant changes to Antigravity's pricing model, introducing weekly credit limits for AI Pro subscribers. Understanding how to allocate and optimize your AI credits is now essential for getting maximum value from your subscription.

This guide breaks down how Antigravity credits work, compares consumption across models, and provides actionable strategies to maximize your development velocity without hitting weekly limits.

Understanding Antigravity's New Plan Structure

Free Plan

The Free tier provides limited access to Gemini Flash. You can build basic prototypes and simple features, but advanced capabilities like complex integrations and multi-model access are restricted.

Characteristics:

• Gemini Flash only
• Monthly credit limits
• Limited API integrations

AI Pro Plan ($20/month)

AI Pro is Antigravity's most popular tier. The March 2026 update introduced weekly credit limits: you get 20,000 credits per week (roughly 80,000 per month across 4 weeks).

Characteristics:

• Access to Gemini Flash and Gemini Pro
• 20,000 credits per week
• Supports most development workflows
• Can switch between models for different tasks

AI Ultra Plan ($60/month)

AI Ultra removes credit constraints entirely. It's designed for teams, complex projects, and developers who need unrestricted access to all models.

Characteristics:

• Unlimited credits
• Access to Gemini Flash, Pro, Claude, and future models
• Priority API resource allocation
• Custom model fine-tuning support

Credit Consumption by Model

Different AI models have dramatically different credit costs. Choosing the right model for each task is the key to staying within limits.

Gemini Flash (Low Cost)

Flash is fast, cheap, and perfect for iterative work. It excels at small tasks and refinements.

When to use Flash:

• Multiple iterative refinements
• Quick prototyping and experimentation
• Small feature additions
• Design polish and alignment adjustments

Gemini Pro (Medium Cost)

Pro offers stronger reasoning and works well for complex logic, API integrations, and multi-step processes.

When to use Pro:

• Production-grade code generation
• Complex multi-step integrations
• Algorithmic problem-solving
• Architectural advice

Claude (Advanced Reasoning)

Claude from Anthropic excels at understanding nuanced requirements and producing thoughtful, well-structured code. It's more expensive but often produces fewer revisions.

When to use Claude:

• Complex problem-solving
• When you need deep reasoning
• Architectural decisions
• Comprehensive documentation

Pro Plan Strategy: Weekly Allocation Framework

With 20,000 credits per week, you need a deliberate allocation strategy.

Allocation Model A: Iterative Development

For projects requiring frequent iterations and refinements:

Gemini Flash      : 8,000 credits (40%)
  └ 80-160 small tasks
     (style tweaks, copy edits, minor fixes)

Gemini Pro        : 8,000 credits (40%)
  └ 20-40 complex features
     (integrations, business logic, schema design)

Experimentation   : 4,000 credits (20%)
  └ New feature prototypes, API exploration

Allocation Model B: Production Development

For projects focused on shipping production features:

Gemini Pro        : 12,000 credits (60%)
  └ High-quality, robust features

Gemini Flash      : 5,000 credits (25%)
  └ Polish, bug fixes, refinements

Reserve           : 3,000 credits (15%)
  └ Unexpected needs, emergency fixes

Allocation Model C: Balanced

A middle-ground approach for sustainable development:

Gemini Flash      : 6,000 credits (30%)
Gemini Pro        : 10,000 credits (50%)
Claude            : 2,000 credits (10%)
Reserve           : 2,000 credits (10%)

Practical Credit-Saving Techniques

1. Prefer Flash for Small Tasks

Flash can handle 80% of routine work at a fraction of Pro's cost.

❌ Don't: "Change the button color from blue to red" (using Pro) = 200 credits
✅ Do: "Change the button color from blue to red" (using Flash) = 40 credits

Savings: 80% per task

2. Batch Multiple Changes Into One Request

Group related tasks into a single prompt. The AI handles multiple edits in one generation.

❌ Don't:
"Add a loading spinner" = 60 credits
"Fix padding on the form" = 50 credits
"Add error messaging" = 70 credits
Total: 180 credits

✅ Do:
"Add a loading spinner, fix padding on the form, and add error messaging"
= 100 credits (one request handles all)

Savings: 44% by batching

3. Write Detailed Prompts Upfront

Vague requests require multiple revisions, each consuming credits. A comprehensive initial prompt reduces back-and-forth.

❌ Don't:
"Build a dashboard" (200 credits)
→ "Add user filtering" (150 credits)
→ "Make it responsive" (120 credits)
→ "Dark mode" (100 credits)
Total: 570 credits

✅ Do:
"Build a user management dashboard with:
- User list table with sorting
- Real-time search filter
- Edit/delete buttons
- Firebase Firestore backend
- Responsive design for mobile
- Dark mode toggle
- Loading states"
= 350 credits (all included in first request)

Savings: 39% with clear specs

4. Use Sprint Reviews for Rapid Iteration

Run weekly development sprints. On Friday, identify what worked well for the following week's focus.

Week N:
- Monday-Wednesday: Build core features (Gemini Pro)
- Thursday-Friday: Polish and test (Gemini Flash)
- Use remaining credits for experimentation

Week N+1:
- Carry forward learnings
- Focus on high-impact features

5. Don't Let Credits Expire

Unused credits reset weekly and disappear. Use remaining Friday credits for:

• Testing new UI patterns
• Refactoring technical debt
• Building bonus features
• Generating documentation

Deciding Between Pro and Ultra

Upgrade to Ultra if:

• You hit the weekly limit every week
• You're working on multiple concurrent projects
• Your team is 3+ developers sharing one account (each should have their own account, but if sharing, use Ultra)
• You're using Claude frequently
• You're experimenting with advanced features like fine-tuning

Stay on Pro if:

• You generate 1-2 projects monthly
• Most tasks use Flash
• Your weekly spend is under 12,000 credits
• You have time to wait for weekly resets

Calculate ROI:

Pro cost per 1,000 credits: $20 ÷ 80,000 = $0.00025
Ultra cost per 1,000 credits: $60 ÷ unlimited = effectively $0 for high usage

If you frequently max Pro: 80,000 credits × $0.00025 = $20 + (overflow)
Ultra gives you 3x the "effective credits" for 3x the price, a fair trade

Monitoring and Analytics

Track your credit spending with Antigravity's built-in analytics:

1. Visit Settings > Billing > Usage
2. Review weekly consumption trends
3. Identify which models you use most
4. Adjust allocation based on actual spending

Weekly spending audit template:

Week of March 24:
Flash:     3,200 credits (16%)
Pro:       12,400 credits (62%)
Claude:    2,100 credits (10.5%)
Reserve:   2,300 credits (11.5%)
Status:    ✅ Under limit (20,000)

Looking back

Credit optimization in Antigravity is about strategic model selection and workflow planning:

1. Use Flash for 80% of work — rapid iterations, small fixes, polish
2. Reserve Pro for complexity — integrations, business logic, complex features
3. Batch requests — group related tasks to reduce overhead
4. Plan ahead — detailed upfront specs beat vague requests + revisions
5. Monitor spending — adjust weekly allocation based on actual patterns
6. Don't waste credits — use Friday's remainder for experimentation

For teams and complex projects, Ultra's unlimited credits often provide better ROI than managing Pro's weekly constraints. Start with Pro, measure your actual consumption, then decide if Ultra makes sense for your workflow.
