Billing Mode Priority
LaoZhang 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
Your billing method is also affected by token configuration: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:- Image Generation
- Video Generation
- Special Models
Applicable Models:
- sora_image series (reverse-engineered models)
- flux-kontext-pro (official models)
- DALL-E series
- Midjourney related models

💸 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
- “你好世界” = 4 tokens
- “Hello World” = 2 tokens
- A WeChat article (2000 characters) ≈ 4000 tokens
Actual Consumption Examples
| Use Case | Input Tokens | Output Tokens | Total | Cost (gpt-4.1-mini) |
|---|---|---|---|---|
| Simple Q&A | 20 | 50 | 70 | $0.00004 |
| Write an article | 100 | 2000 | 2100 | $0.0013 |
| Code Debug | 500 | 300 | 800 | $0.00027 |
| Long text translation | 5000 | 5000 | 10000 | $0.0035 |
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.
