# Chat GPT

> Send a message to OpenAI GPT-4 and get a response

### Description

Send AI chat messages using OpenAI's Chat GPT provider through Plura. Use this integration when you want to power conversations with OpenAI models (such as GPT-5, GPT-4.5, GPT-4o) from within your Plura workflows.

### Authentication

* Configure your OpenAI API key or organization credentials in your Plura workspace settings.

### Available Actions

* List available OpenAI models
* Execute chat completions with OpenAI models
* Support for multiple GPT models (GPT-5, GPT-4.5, GPT-4o, GPT-4.1)

### Examples

**Example 1: Chat GPT - List Models**

    "params": {
      "provider": "openai"
    }
  }
}
```

**Example 2: Chat GPT - Chat Completion (GPT-5 Mini)**
