This is a simple F# console application that uses the OpenAI API to generate text completions with the GPT-4 language model.

• Sends requests to the OpenAI API to generate text completions based on a given prompt.
• Supports setting maximum tokens and number of generated text choices.
• Reads the API key from an environment variable or command-line argument.
• Handles API responses and displays generated text.

• FSharp.Data: Used for the JSON type provider.
• System.Net.Http: Used for making HTTP requests to the OpenAI API.
• Argu: Used for command-line argument parsing.

1. Install the .NET SDK for your operating system from the .NET download page.
2. Run dotnet restore in the project directory to install the required F# libraries.

• Windows:

  setx OPENAI_API_KEY "your_api_key"
  

• Linux and macOS:

  export OPENAI_API_KEY="your_api_key"
  

Replace "your_api_key" with your actual OpenAI API key.

1. Build the project with dotnet build.
2. Run the application with the following command:

• Windows:

  dotnet run -- --api-key %OPENAI_API_KEY% --prompt "your_prompt" [--max-tokens max_tokens] [--n n]
  

• Linux and macOS:

  dotnet run -- --api-key $OPENAI_API_KEY --prompt "your_prompt" [--max-tokens max_tokens] [--n n]
  

Replace the following placeholders:

• "your_prompt": The text prompt you want to use for the GPT-4 model.
• max_tokens: The maximum number of tokens you want in the generated text (default is 50).
• n: The number of generated text choices (default is 1).

To generate a text completion using the GPT-4 model with the prompt "Tell me something interesting about human life.", run:

dotnet run -- --api-key your_api_key --prompt "Tell me something interesting about human life."

Replace your_api_key with your actual OpenAI API key.
