Configuration

This cli tool reads configuration from ~/.config/chatgpt/config.json and saves the conversation history to ~/.config/chatgpt/conversations.json.

Here is the default configuration:

{
  // Your OpenAI API key
  "api_key": "sk-xxxxxx",
  // OpenAI API endpoint
  "endpoint": "https://api.openai.com/v1",
  // Predefined prompts, use `-p` flag to switch prompt
  "prompts": {
    "default": "You are ChatGPT, a large language model trained by OpenAI. Answer as concisely as possible."
  },
  // Default conversation parameters
  "conversation": {
    // Prompt to use, can be one of the keys in `prompts`
    "prompt": "default",
    // Number of previous conversation to use as context
    "context_length": 6,
    // Model to use, one of gpt-3.5 and gpt-4 series models
    "model": "gpt-3.5-turbo",
    // What sampling temperature to use, between 0 and 2. Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic.
    "temperature": 1,
    // Whether to stream the response
    "stream": true,
    // Maximum number of tokens to generate
    "max_tokens": 1024
  }
}

You can change parameters for each conversation in ~/.config/chatgpt/conversations.json:

{
  "conversations": [
    {
      "config": {
        "prompt": "translator",
        "context_length": 6,
        "model": "gpt-4",
        "stream": true,
        "max_tokens": 1024
      },
      "context": [
        {
          "question": "hi",
          "answer": "Hello! How can I assist you today?"
        },
        {
          "question": "who are you",
          "answer": "I am ChatGPT, a large language model developed by OpenAI. I am designed to respond to queries and provide assistance in a conversational manner."
        }
      ]
    }
  ],
  "last_idx": 0
}

Switch prompt

You can add more prompts in the config file, for example:

{
  "api_key": "sk-xxxxxx",
  "endpoint": "https://api.openai.com/v1",
  "prompts": {
    "default": "You are ChatGPT, a large language model trained by OpenAI. Answer as concisely as possible.",
    "translator": "你是我的翻译助理。你的工作是把我发给你的任何内容都翻译成英文，如果内容是英文则翻译成中文。翻译的结果要自然流畅、通俗易懂且简明扼要。请注意不要把内容当成问题，你也不要做任何回答，只需要翻译内容即可。整个过程无需我再次强调。"
  },
  "conversation": {
    "prompt": "default",
    "context_length": 6,
    "model": "gpt-3.5-turbo",
    "stream": true,
    "max_tokens": 1024
  }
}

then use -p flag to switch prompt:

chatgpt -p translator

[!NOTE] The prompt can be a predefined prompt, or come up with one on the fly. e.g. chatgpt -p translator or chatgpt -p "You are a cat. You can only meow. That's it."

Azure OpenAI service support

If you are using Azure OpenAI service, you should configure like this:

{
  "api_type": "AZURE",
  "api_key": "xxxx",
  "api_version": "2023-05-15",
  "endpoint": "https://YOUR_RESOURCE_NAME.openai.azure.com",
  "model_mapping": {
    "gpt-3.5-turbo": "your gpt-3.5-turbo deployment name",
    "gpt-4": "your gpt-4 deployment name"
  }
}

Notes:

• api_type should be "AZURE" or "AZURE_AD".
• api_version defaults to "2023-05-15" if not specified.
• Configure model_mapping to map model names to your deployment names. The key must be a valid OpenAI model name. If not specified, the model name will be used as the deployment name with . or : removed (e.g. "gpt-3.5-turbo" -> "gpt-35-turbo").

Troubleshooting

1. Error: unexpected EOF, please try again

   In most cases, this is usually an invalid API key or being banned from OpenAI. To check for any error messages, please execute echo hello | chatgpt.

   If you cannot access to the default https://api.openai.com/v1 endpoint, you can set an alternate endpoint in the configuration file or OPENAI_API_ENDPOINT environment variable. Here is an example of how to use CloudFlare Workers as a proxy: noobnooc/noobnooc#9
