Billing Modes
LaoZhang API supports two billing modes. When a model supports both modes simultaneously: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:- Image Generation
- Video Generation
- Special Models
Applicable Models:
- GPT-Image-2 family
- Nano Banana family
- flux-kontext-pro

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
- “Hello World” = 2 tokens
- A typical article (2000 words) ≈ 3000 tokens
Usage Examples Without Fixed Prices
These numbers only illustrate the calculation method. Actual token counts depend on model tokenization, context, tool calls, and output length. Apply the target model’s current input, output, cached-token, or per-call price.
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

Cost Estimation Method
1
Small Sample Testing
Test with a small number of samples (5-10)
2
Check Consumption Logs
View detailed token consumption for each call in console
3
Calculate Average
Calculate average token count per call
4
Estimate Total Cost
(Average input tokens × input price + average output tokens × output price) × expected calls; add per-call, per-image, or per-second charges where applicable
Practical Recommendations
- Test with lower-cost models first to verify feasibility
- Analyze actual consumption through backend logs
- Choose appropriate models based on task complexity
- Optimize prompts to reduce unnecessary token consumption
