Billing

Manage credits, monitor usage, and track spending for GPU instances.

Credit system

• 1 Credit = $1 USD of GPU usage
• Credits never expire
• Credits are shared across team members
• Pay-per-second billing: credits are deducted continuously based on your hourly rate, so you pay only for the exact time your instance runs

• Minimum deposit: $15
• Minimum deployment: $3
• Instant credit delivery

Dashboard overview

Current Balance: Available credits for GPU deployments

This Month: Total spending for the current calendar month

Active Instances: Number of currently running GPU instances

Adding credits

Payment methods

Card payment (powered by Stripe)

• Visa, Mastercard, and major cards accepted
• Secure processing via Stripe
• Instant delivery

Custom amount

Enter any amount between $15 (minimum) and $5,000 (maximum) for instant delivery.

Usage analytics

Track all GPU deployments and associated costs.

• Total Deployments: all-time instance count
• This Month: current month deployments (resets monthly)

• Instance ID and GPU type
• Location and duration
• Timestamp and cost
• Status (active/terminated)

Use the analytics view for:

• Cost analysis by GPU type
• Monthly spending patterns
• Project cost tracking
• Usage optimization

Transaction history

View all credit purchases and payment records.

• Purchase date and amount
• Payment method (card/crypto)
• Transaction status

Use the transaction history for:

• Payment verification
• Expense tracking
• Accounting records

Auto top-up

Auto top-up prevents unexpected instance termination by automatically recharging your account when credits run low.

1. Save a payment card in Billing > Payment Method
2. Set a minimum balance threshold ($5-$500, e.g., $20); when your balance drops below this amount, a charge is triggered
3. Set a top-up amount ($15-$5,000, e.g., $100); this is how much is charged each time
4. Toggle Auto Top-Up on; the platform charges your saved card when the balance falls below the threshold

Configure via: Dashboard > Billing > Auto Top-Up

A 5-minute cooldown between charges prevents duplicate billing. If a charge fails, auto top-up is automatically disabled and you receive an email notification. Auto top-up charges appear in Deposit History labeled "Auto Top-Up".

For long training runs, auto top-up prevents instance termination due to insufficient credits mid-job.

Team discounts

Volume-based and admin-assigned discounts apply automatically. The discounted price appears directly in the GPU listings on the dashboard when your team has an active discount.

• The higher of volume-based or admin-assigned discounts is applied automatically
• No action is required; discounts apply as long as you are authenticated

To inquire about discount eligibility for high-volume usage, contact support via Discord or email.

Best practices

• Start with $50-$100 to understand usage patterns
• Monitor balance regularly for long-running instances
• Enable Auto Top-Up to avoid unexpected terminations
• Set up billing alerts in User Settings
• Use custom amounts for precise budgeting

• Review usage analytics to identify expensive deployments
• Terminate unused instances promptly
• Use Reserved GPUs for long-term workloads (30-50% savings)
• See Cost Optimization for GPU tier selection and Spot strategies

• Card payments are Stripe-encrypted and PCI compliant
• Crypto payments are blockchain-secured via CopperX
• Card data is never stored on Spheron servers

Frequently asked questions

Q: What happens if I run out of credits?
