​
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
  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

from openai import OpenAI

client = OpenAI(
    api_key="sk-xxx",
    base_url="https://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)
GPTs calls require upstream channel support. Not all GPTs are available - availability depends on channel configuration.
GPTs conversations support streaming output by setting stream: true. Billing is calculated based on GPT-4 model pricing.
