qBraid Lab Platform V2 introduces usage limits to help you manage your resources effectively. These limits vary based on your subscription plan and can be monitored from your account dashboard.
Compute Hours
Each user is provided a set number of compute hours per month, which varies depending on your subscription plan. Compute hours track the time your Lab instances are actively running.
Compute hours are a unit of measure that combines the number of CPU cores used
multiplied by the number of hours used. For example, running a 2-vCPU instance
for 3 hours uses 6 CPU hours, and running an 8-vCPU instance for 2 hours uses
16 CPU hours.
- Usage is tracked across all running Lab instances
- Compute hours reset at the end of each month
- Monthly allocations by plan:
| Plan | Compute Hours/Month |
|---|
| Free | 25 CPU hours |
| Standard | 400 CPU hours |
| Pro | 2000 CPU hours |
- Navigate to Account > Usage > Compute Settings
- Enable the Auto-switch to credits option
- Credits will be consumed automatically when
compute hours run out
This ensures uninterrupted access to your Lab instances throughout the month.
Disk Usage
Users are allocated a limited amount of disk storage based on their subscription tier. It is the user’s responsibility to
monitor their storage usage and ensure compliance with their assigned quota.
| Plan | Disk Storage |
|---|
| Free | 15 GB |
| Standard | 50 GB |
| Pro | 150 GB |
Exceeding Disk Usage Quotas
- If a user exceeds their allocated disk space, they will receive a notification prompting them to delete files to stay within their quota.
- If the user does not reduce their storage usage within the allotted time, their qBraid Lab session will be terminated.
- Upon logging back in, the user must reduce their disk usage before resuming services.
- This process will repeat until the user meets the disk usage quota.
Disk Usage Management
Your installed qBraid Lab environments often occupy the most disk space. To free up space, consider uninstalling any environments you no longer use.
To analyze your disk usage in detail, open the Terminal and run the gdu command:
gdu [flags] [directory_to_scan]
gdu, refer to the official documentation.
Once you’ve identified large or unwanted files and directories, you can delete them using the rm command in the Terminal:
rm -rf [directory_to_delete]
AI Chat Usage
Each user receives a monthly quota for AI Chat prompts, which varies by subscription plan. This quota covers interactions with qBraid’s AI assistant features.
Auto-switch to Credits:
Similar to compute hours, you can enable automatic credit consumption when your AI chat quota is exhausted:
- Navigate to Account > Usage > AI Chat Usage
- Enable the Auto-switch to credits option
- Credits will be used for additional AI chat prompts once your quota is exhausted
This feature ensures continuous access to AI assistance throughout the month, even after your base quota is used.
Monitoring Usage:
All usage metrics can be monitored in real-time from your account dashboard. Navigate to Account > Usage to view detailed breakdowns of your compute hours, disk storage, and AI chat consumption.
