## Enterprise Technical Service Pricing

### Service Positioning

LaoZhang API provides **enterprise-grade AI technical API integration services** for enterprises and developers:

* **Service Nature**: Information technology service / API integration service
* **Target Customers**: Enterprise users, development teams, technical departments
* **Billing Method**: Token/per-call billing, pay-as-you-go, no monthly fees

<CardGroup cols={2}>
  <Card title="Transparent Pricing" icon="tags">
    Most model prices are transparent and public, consumption fully trackable
  </Card>

  <Card title="Complete Models, Fast Updates" icon="bell-dot">
    Whenever manufacturers release new models, LaoZhang API is always quick to update
  </Card>
</CardGroup>

<Note>
  The featured models on this page were updated on **July 23, 2026**. LaoZhang API gateway pricing, upstream provider pricing, and third-party subscriptions are separate billing contracts. Confirm exact model IDs, token groups, billing modes, and live prices on the [console pricing page](https://api2.laozhang.ai/account/pricing).
</Note>

  </Tab>

  <Tab title="Enterprise">
    **Enterprise Exclusive Service**:

    * Enterprise quotes available through support

### Cost Estimation Reference

<Card title="Current Model Selection Reference" icon="calculator">
  **Choose a model first, then estimate cost with representative requests:**

  * **High-volume classification and extraction**: `gemini-3.5-flash-lite`, `gpt-5.6-luna`
  * **General multimodal and agent work**: `gemini-3.6-flash`, `gpt-5.6-terra`
  * **Coding and complex tasks**: `claude-sonnet-5`, `gpt-5.6`
  * **Image generation**: `gpt-image-2`, `gemini-3.1-flash-image`

  This page no longer uses historical fixed estimates such as “1,000 calls cost about X.” Production budgets should use a small-volume test, actual token or per-call usage from logs, and current console pricing.
</Card>

## Usage Monitoring & Management

### Console Features

<Tabs>
  <Tab title="Usage Monitoring">
    **Real-time Dashboard**

  </Tab>

  <Tab title="Cost Optimization">
    **Technical Optimization Recommendations**

    1. Use `max_tokens` to limit output
    2. Choose appropriate `temperature`
    3. Cache frequently used responses
    4. Batch process requests
    5. Use streaming output to reduce timeouts
  </Tab>
</Tabs>

### Billing Modes

LaoZhang API supports two billing modes. When a model supports both modes simultaneously:

<Warning>
  **Per-call billing takes priority over token-based billing**

  If a model supports both per-call and token-based billing, the system defaults to per-call billing.
</Warning>

#### API Key Settings Impact

<CardGroup cols={2}>
  <Card title="Token-based Only" icon="sliders-horizontal">
    If token is set to "token-based only", even if the model supports per-call billing, it will use token-based billing
  </Card>

  <Card title="Default Settings" icon="circle-check">
    Tokens support all billing modes by default, system auto-selects (per-call priority)
  </Card>
</CardGroup>

### Per-call Billing Scenarios

The following types of models typically use per-call billing:

<Tabs>
  <Tab title="Image Generation">
    **Applicable Models**:

    * GPT-Image-2 family
    * Nano Banana family
    * flux-kontext-pro

    **Billing Unit**: Per image, per call, or usage-based depending on the route
  </Tab>

  <Tab title="Video Generation">
    **Applicable Models**:

    * Video generation APIs
    * Animation production models

    **Billing Unit**: Per video/per second
  </Tab>

  <Tab title="Special Models">
    **Identification Method**:

    **Billing Unit**: Per call
  </Tab>
</Tabs>

## Token Billing Explanation

### What are Tokens?

<Card title="Understanding Tokens Quickly" icon="coins">
  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
</Card>

### Usage Examples Without Fixed Prices

| Use Case              | Example Input Tokens | Example Output Tokens | Example Total |
| --------------------- | -------------------- | --------------------- | ------------- |
| Simple Q\&A           | 20                   | 50                    | 70            |
| Article generation    | 100                  | 2000                  | 2100          |
| Code debugging        | 500                  | 300                   | 800           |
| Long text translation | 5000                 | 5000                  | 10000         |

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:

<Steps>
  <Step title="Prompt - Input Tokens">
    All content you send to the model, including:

    * System prompts
    * User questions
    * Context information
    * Chat history (if any)
  </Step>

  <Step title="Completion - Output Tokens">
    Content generated by the model, including:

    * Text responses
    * Code generation
    * Structured data
  </Step>
</Steps>

<Warning>
  Input, output, cached-token, and per-call prices may vary by model, token group, and route. Do not use an upstream provider's public price to predict a LaoZhang API bill; use the console and call logs.
</Warning>
