Google Cloud Quota Check: G3 Pro/Image/Flash and Claude

What You'll Learn

• View quotas for 4 models on Google Cloud Antigravity accounts
• Understand reset time and remaining percentage for each model
• Manage quota usage across multiple Google Cloud accounts

Your Current Pain Point

Google Cloud Antigravity provides multiple models (G3 Pro, G3 Image, G3 Flash, Claude), each with independent quotas and reset times. You need to:

• Log into Google Cloud Console separately to check each model's status
• Manually calculate remaining quotas and reset times
• It's even more chaotic when managing multiple accounts

When to Use This

When you:

• Want to quickly check remaining quotas for all Google Cloud models
• Need to plan usage allocation across different models
• Have multiple Google Cloud accounts to manage uniformly

🎒 Prerequisites

Prerequisites Check

1. mystatus plugin installed: Refer to Quick Start
2. Google Cloud authentication configured: First install opencode-antigravity-auth plugin to complete OAuth authentication
3. Authentication file exists: ~/.config/opencode/antigravity-accounts.json contains at least one account

Core Concept

Google Cloud Antigravity authenticates via OAuth mechanism, with each account having an independent Refresh Token. The mystatus plugin will:

1. Read antigravity-accounts.json to get all configured accounts
2. Use Refresh Token to refresh Access Token
3. Call Google Cloud API to get quotas for all models
4. Display quotas and reset times for 4 models, grouped by account

Google Cloud Supported Models

mystatus displays quotas for the following 4 models:

Display Name	Model Key (Primary/Backup)	Description
G3 Pro	gemini-3-pro-high / gemini-3-pro-low	Gemini 3 Pro high-performance version
G3 Image	gemini-3-pro-image	Gemini 3 Pro image generation
G3 Flash	gemini-3-flash	Gemini 3 Flash fast version
Claude	claude-opus-4-5-thinking / claude-opus-4-5	Claude Opus 4.5 model

Primary Key and Backup Key Mechanism:

• API response may return data for only primary key or backup key
• mystatus automatically attempts to fetch quota for either key
• For example: if gemini-3-pro-high has no data, it will try gemini-3-pro-low

Follow Along

Step 1: Execute Query Command

Why Quickly get quota information for all Google Cloud accounts

/mystatus

You Should See Quota information for all configured platforms, where the Google Cloud section will show content similar to:

## Google Cloud Account Quota

### user@gmail.com

G3 Pro     4h 59m     ████████████████████ 100%
G3 Image   4h 59m     ████████████████████ 100%
G3 Flash   4h 59m     ████████████████████ 100%
Claude     2d 9h      ░░░░░░░░░░░░░░░░░░░░ 0%

Step 2: Understand Output Format

Why Quickly locate key information: remaining quota and reset time

Each line format:

[model name] [reset time] [progress bar] [remaining percentage]

Field Description:

• Model name: G3 Pro, G3 Image, G3 Flash, Claude
• Reset time: Time remaining until next quota reset (e.g., 4h 59m, 2d 9h)
• Progress bar: Visual display of remaining percentage
• Remaining percentage: Value from 0-100

You Should See One line per model, clearly showing quota and reset time

Step 3: View Multiple Accounts

Why If you have multiple Google Cloud accounts, they will be displayed separately

### user@gmail.com

G3 Pro     4h 59m     ████████████████████ 100%
G3 Image   4h 59m     ████████████████████ 100%

### another@gmail.com

G3 Pro     2h 30m     ████████████░░░░░░░░░ 75%
G3 Image   2h 30m     ████████████░░░░░░░░░ 75%

You Should See Each account in a separate section, containing that account's 4 model quotas

Step 4: Check Quota Warnings

Why Avoid service interruption due to overuse

If usage of any model exceeds 80%, a warning prompt will appear:

### user@gmail.com

G3 Pro     1h 30m     ████░░░░░░░░░░░░░░░ 20%
G3 Image   1h 30m     ████░░░░░░░░░░░░░░ 20%

⚠️ Usage has reached or exceeded 80%

You Should See Warning prompt appears below the model list for the corresponding account

Checkpoint ✅

Complete the following checks to ensure you did it correctly:

• [ ] Can see Google Cloud quota information after running /mystatus
• [ ] Can understand the names and reset times for 4 models
• [ ] Can identify progress bars and remaining percentages
• [ ] If multiple accounts exist, can see quotas for all accounts

Common Pitfalls

Problem 1: Cannot See Google Cloud Quota

Possible Causes:

• opencode-antigravity-auth plugin not installed
• Google OAuth authentication not completed
• antigravity-accounts.json file doesn't exist or is empty

Solution:

1. Install opencode-antigravity-auth plugin
2. Complete authentication following the GitHub repository instructions
3. Run /mystatus again

Problem 2: Error Displayed for an Account

Possible Causes:

• Refresh Token expired
• projectId missing

Error Example:

user@gmail.com: No project ID found

Solution:

1. Re-authenticate that account using opencode-antigravity-auth plugin
2. Ensure project ID is correctly set during authentication

Problem 3: Model Shows "-" or Reset Time Abnormal

Possible Causes:

• API response resetTime field missing or in wrong format
• No quota information available for that model

Solution:

• This is normal, mystatus displays "-" to indicate data unavailable
• If all models show "-", check network connection or Google Cloud API status

Summary

• Google Cloud Antigravity supports 4 models: G3 Pro, G3 Image, G3 Flash, Claude
• Each model has independent quotas and reset times
• Supports multi-account management, with each account displayed separately
• Warning prompt appears when usage exceeds 80%
