Credits System

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.

What Are Credits?

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.

Free Credits for New Users

Free welcome credits on sign-up
1,000 credits
Automatically added to every new account — no credit card required
No credit card required

When you create a new LLM Resayil account, you automatically receive 1,000 free credits to get started. This allowance is sufficient for hundreds of requests with local models, letting you evaluate the platform and explore available models before making any purchase decision.

No credit card required: The welcome credit is available immediately upon registration with no payment details needed.

Credit-Based Billing

LLM Resayil uses a pay-per-use billing model. Deduction happens immediately after each completed request based on the following formula:

(prompt_tokens input tokens
+
completion_tokens) output tokens
×
model_multiplier model multiplier
=
credits_deducted deducted

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.

Credit Rates by Model Tier

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:

Standard Models
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
Frontier Models
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.

Checking Your Balance

You can check your current balance in two ways:

  • Dashboard: Your balance is displayed at the top of your account's main page.
  • Via API: Use the GET /api/billing/subscription endpoint to query programmatically.
GET https://llmapi.resayil.io/api/billing/subscription
JSON Response
{ "tier": "free", "status": "active", "expires_at": null, "credits": 732.00 }

What Happens When Credits Run Out

When you attempt a request and your balance is insufficient to cover it, the server immediately rejects the request and returns an HTTP error:

402 Payment Required — Insufficient Credits

Server response when balance is exhausted:

HTTP / JSON
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.

Subscription Credits vs Top-Up Credits

Your account can hold two types of credits that work together seamlessly:

Subscription Credits

Credits allocated as part of a recurring subscription plan. Renewed when the subscription renews. The free-tier welcome credit (1,000 credits at registration) falls under this type.

Top-Up Credits

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.
