Billing Modes

LaoZhang API supports two billing modes. When a model supports both modes simultaneously:
Per-call billing takes priority over token-based billingIf a model supports both per-call and token-based billing, the system defaults to per-call billing.

API Key Settings Impact

Token-based Only

If token is set to “token-based only”, even if the model supports per-call billing, it will use token-based billing

Default Settings

Tokens support all billing modes by default, system auto-selects (per-call priority)

Per-call Billing Scenarios

The following types of models typically use per-call billing:
Applicable Models:
  • sora_image series
  • flux-kontext-pro
  • DALL-E series
Billing Unit: Per image

Token Billing Explanation

What are Tokens?

Understanding Tokens Quickly

Tokens are AI’s “vocabulary units”, the basic unit for billing.Simple Memory:
  • 1 Chinese character ≈ 2 tokens
  • 1 English word ≈ 1 token
  • 500 Chinese characters ≈ 1000 tokens
Real Examples:
  • “Hello World” = 2 tokens
  • A typical article (2000 words) ≈ 3000 tokens

Prompts and Completions

In each API call, costs consist of two parts:
1

Prompt - Input Tokens

All content you send to the model, including:
  • System prompts
  • User questions
  • Context information
  • Chat history (if any)
2

Completion - Output Tokens

Content generated by the model, including:
  • Text responses
  • Code generation
  • Structured data
Input and output prices may differ between models. Typically, output tokens cost more than input tokens.

Cost Estimation Method

1

Small Sample Testing

Test with a small number of samples (5-10)
2

Check Consumption Logs

3

Calculate Average

Calculate average token count per call
4

Estimate Total Cost

Average tokens × Expected calls × Model unit price

Practical Recommendations

  1. Test with lower-cost models first to verify feasibility
  2. Analyze actual consumption through backend logs
  3. Choose appropriate models based on task complexity
  4. Optimize prompts to reduce unnecessary token consumption
