A comprehensive guide to understanding the LLM Resayil credits system — how credits work, how they are calculated, and what happens when your balance runs out.
Credits are the unit of payment in LLM Resayil. Rather than paying in dollars directly per request, a credit amount is deducted from your account based on the number of tokens consumed and the model used. This system gives you complete flexibility — you pay only for what you use, with no fixed fees or mandatory subscriptions.
LLM Resayil runs on prepaid credits. Create your account, buy a credit pack from Billing & Plans, and start immediately. Every model has a published rate in credits per 1,000 tokens, and your balance can be spent on any model you choose with no monthly commitment.
Start cheaply: our fastest models are charged at a fraction of the premium rate, so a small first pack goes a long way while you evaluate the platform.
LLM Resayil uses a pay-per-use billing model. Deduction happens immediately after each completed request based on the following formula:
There are no monthly subscription fees and no standing charges. Your credit balance remains intact until you use it — whether that takes a week, a month, or longer.
The credit deduction rate varies by model tier — Standard Models or Frontier Models. Choose the right tier for your use case to get the most from your credits:
| Model Type | Multiplier | Examples | Best For |
|---|---|---|---|
| Lightweight models | 0.5× | Phi-3 Mini, TinyLlama | Classification, short summaries |
| Standard models | 1.0× | Mistral 7B, Llama 3 8B | General chat, writing, coding |
| Mid-range models | 1.5× | Llama 3 70B, Mixtral 8x7B | Complex reasoning, long content |
| Model Type | Multiplier | Examples | Best For |
|---|---|---|---|
| Frontier Standard | 2.0× – 2.5× | GPT-4o Mini, Claude Haiku | High-accuracy tasks |
| Frontier Large | 3.0× – 3.5× | GPT-4o, Claude 3.5 Sonnet, Gemini Pro | Hardest tasks, multi-step reasoning |
For the exact multiplier of each individual model, refer to the Available Models page.
You can check your current balance in two ways:
GET /api/billing/subscription endpoint to query programmatically.
{
"tier": "free",
"status": "active",
"expires_at": null,
"credits": 732.00
}
When you attempt a request and your balance is insufficient to cover it, the server immediately rejects the request and returns an HTTP error:
Server response when balance is exhausted:
HTTP/1.1 402 Payment Required
{
"error": {
"message": "Insufficient credits. Please top up your balance to continue.",
"type": "insufficient_credits",
"code": 402
}
}
Note: No part of the request is executed if the balance is insufficient — the model is not invoked and no partial credit is deducted.
To resume usage, simply purchase a top-up pack through the Billing page. Credits are added automatically as soon as payment is confirmed.
Your account can hold two types of credits that work together seamlessly:
Credits allocated as part of a recurring subscription plan. Renewed when the subscription renews.
Credits purchased as a one-time top-up, added on top of subscription credits. They do not expire with the subscription and do not renew automatically — they persist until consumed.
When executing requests, the system draws from subscription credits first, then moves to top-up
credits as needed. The GET /api/billing/subscription endpoint shows the combined
available balance from both sources.
