In this article, we’ll show you how to use ChatGPT in Ruby by building a simple command-line application. This application will allow you to generate text based on a prompt that you provide.
OpenAI’s GPT-3 is a cutting-edge language model that has taken the artificial intelligence community by storm. Its ability to generate human-like text is unparalleled, making it a valuable tool for developers. For example, if you’re a Ruby developer, you can easily integrate ChatGPT into your applications.
Setting up OpenAI’s API
Before we dive into the code, we need to set up an API key with OpenAI. This will allow us to access ChatGPT’s language generation capabilities.
- Go to OpenAI’s website and sign up for an account.
- Once you’ve confirmed your email, log into your OpenAI account.
- Navigate to the API section of your account and create a new API key.
- Copy the API key to your clipboard, as you’ll need it in the next section.
Installing the OpenAI Ruby Gem
To use ChatGPT with Ruby, we’ll be using the OpenAI Ruby gem. This gem provides a simple interface for interacting with ChatGPT’s API.
To install the OpenAI gem, run the following command in your terminal:
gem install openai
Building the Command-Line Application
Now that we have our API key and the OpenAI gem installed, we can start building our application.
First, create a new Ruby file in your project directory. We’ll call this file. chatgpt.rb.
Next, we’ll require the OpenAI gem and set up our API key.
ruby
require 'openai'
Openai.api_key = "YOUR_API_KEY"
Next, we’ll write a method that generates text based on your prompt.
ruby
def generate_text(prompt)
response = Openai::Completion.create(
engine: "text-davinci-002",
prompt: prompt,
max_tokens: 100,
n: 1,
stop: "",
temperature: 0.5
)
response["choices"][0]["text"]
end
Finally, we’ll add some code that allows you to interact with the application from the command line.
ruby
puts "Enter a prompt for ChatGPT to complete: "
prompt = gets.chomp
puts "Generated text: \n\n"
puts generate_text(prompt)
And that’s it! When you run your chatgpt.rb file, you can interact with ChatGPT by entering a prompt.
Conclusion
In this article, we showed you how to use ChatGPT with Ruby by building a simple command-line application. By integrating OpenAI’s large language model into your Ruby applications, you can add cutting-edge AI capabilities to your projects.
Whether you’re building a chatbot, a content generation tool, or any other application that requires human-like text generation, ChatGPT is a powerful tool worth exploring.
