# GPTs Conversations

> Call OpenAI GPTs applications via API

> Дата обновления: 2026-06-06

## Overview

Crazyrouter supports calling OpenAI GPTs (custom GPT applications) through the standard Chat Completions API. Simply set the model name to the GPTs-specific format.

## Model Name Format

```
gpt-4-gizmo-{gizmo_id}
```

The `gizmo_id` is the unique identifier for the GPT, which can be extracted from the GPTs URL.

## Getting the Gizmo ID

1. Visit the [ChatGPT GPTs Store](https://chatgpt.com/gpts)
2. Open the target GPT application
3. Extract the ID from the URL: `https://chatgpt.com/g/g-B3hgivKK9-xxx` → ID is `g-B3hgivKK9`

## Code Examples

<CodeGroup>
  ```python Python theme={null}
  from openai import OpenAI

  client = OpenAI(
      api_key="sk-xxx",
      base_url="https://api.crazyrouter.com/v1"
  )

  # Chat with a GPT
  response = client.chat.completions.create(
      model="gpt-4-gizmo-g-B3hgivKK9",
      messages=[
          {"role": "user", "content": "Hello, please introduce yourself"}
      ]
  )

  print(response.choices[0].message.content)
  ```

  ```bash cURL theme={null}
  curl -X POST https://api.crazyrouter.com/v1/chat/completions \
    -H "Authorization: Bearer sk-xxx" \
    -H "Content-Type: application/json" \
    -d '{
      "model": "gpt-4-gizmo-g-B3hgivKK9",
      "messages": [
        {"role": "user", "content": "Hello, please introduce yourself"}
      ]
    }'
  ```

<Warning>
  GPTs calls require upstream channel support. Not all GPTs are available - availability depends on channel configuration.
</Warning>

<Note>
  GPTs conversations support streaming output by setting `stream: true`. Billing is calculated based on GPT-4 model pricing.
