Usage Limits and Billing

MaxLabs supports two billing models:

• Subscription plans
• Pay-as-you-go API billing

A user account can use either a subscription or PAYG at a given time, but not both simultaneously.

Subscription plans are designed for regular development usage, while PAYG is intended for API customers who prefer usage-based billing.

Subscription Plans

MaxLabs currently offers three subscription tiers:

Plan	Relative Usage	Pro Access
$10	1×	No
$50	5×	Yes
$100	10×	Yes

The exact model access and other plan differences are listed on the pricing page.

The $10 plan does not include access to Pro.

How Usage Limits Work

Every subscription includes two independent usage limits:

• A 5-hour rolling limit
• A weekly limit

Both limits reset automatically.

5-Hour Rolling Limit

The 5-hour window starts when you send your first message.

Usage during that period counts against your 5-hour allowance.

Once the window expires, the 5-hour quota becomes available again automatically.

Weekly Limit

Subscriptions also have a weekly usage allowance.

The weekly window begins with your first message and resets automatically at the end of the period.

The higher subscription tiers provide proportionally larger allowances:

• $10 plan — 1×
• $50 plan — 5×
• $100 plan — 10×

The 5-hour and weekly limits operate together. Reaching either limit can temporarily prevent additional subscription usage until the relevant window resets.

Disabling the 5-Hour Limit

The 5-hour rolling limit can optionally be disabled from your account settings.

This is useful if you prefer to consume more of your weekly allowance during a smaller number of focused development sessions.

When the 5-hour limit is disabled, your weekly allowance still applies.

Disabling it does not increase the total weekly quota. It only changes how quickly you can consume that quota.

When Limits Reset

Usage windows reset automatically.

• The 5-hour window becomes available again after its current rolling period ends.
• The weekly allowance becomes available again when the weekly period resets.

Because these limits are tied to your actual usage window, they begin from your first message rather than from a fixed calendar boundary.

Pay-As-You-Go API Billing

API users can choose PAYG instead of a subscription.

With PAYG, usage is charged against your MaxLabs wallet rather than a weekly or 5-hour subscription allowance.

A user account cannot simultaneously operate as both PAYG and subscription billing.

You can switch between the two.

Switching From Subscription to PAYG

When you move from a subscription to PAYG, MaxLabs calculates the unused prorated value of your eligible subscription.

That value is credited to your PAYG wallet after applicable usage and adjustments are accounted for.

Switching From PAYG to a Subscription

When you move from PAYG to a subscription, your available PAYG wallet balance can be applied toward the subscription purchase.

If sufficient wallet balance remains, MaxLabs can also use it toward subsequent subscription renewals.

Any remaining wallet balance stays associated with your account.

Refunds

PAYG wallet balance can be refunded where applicable.

To request a refund, contact:

support@cenmax.in

Eligible subscription customers may also request a prorated refund.

Any applicable API usage costs are deducted before the refundable balance is calculated.

Refund eligibility may depend on the account, subscription status, usage already consumed, and other applicable billing conditions.

Subscription or PAYG?

Use a subscription when you expect regular development usage and want a predictable recurring allowance.

Use PAYG when you primarily use the API, have irregular usage, or prefer usage-based billing.

Regular development usage → Subscription

Variable API usage → PAYG

You can switch between the two billing models without losing eligible account value, because prorated subscription value and PAYG wallet balance can be carried across according to the rules above.
