## What is Artificial Intelligence (AI)?
Artificial intelligence is the simulation of human intelligence processes by machines.

## What is OpenAI?
OpenAI is a platform that created a model called ChatGPT to interact in a conversational way. As a user, you can ask appropriate questions on ChatGPT and your questions will be answered immediately. 

## What is ChatGPT?
ChatGPT is a revolutionary technology that has been developed by OpenAI, based on the GPT-3.5 architecture. This artificial intelligence model has been trained on a large amount of text data, and it is capable of generating human-like responses to a wide range of queries. (AMAZING!)

One of the most advantages of ChatGPT is its ability to generate human-like responses. This is achieved through a process called natural language generation (NLG), which allows the model to generate responses that are both grammatically correct and contextually relevant.

Another advantage of ChatGPT is its ability to learn from its interactions with users. This means that the more it is used, the more accurate and effective it becomes. This is achieved through a process called machine learning, which allows the model to learn from its mistakes and improve its responses over time.

ChatGPT has already been used in a variety of applications, including customer service chatbots, personal assistants, and even in gaming. In each of these applications, ChatGPT has proven to be effective in providing a natural and engaging user experience.

## What is an API?
API stands for application programming interface, which is a set of definitions and protocols for building and integrating application software.

## So what?
Well... Now you (may) know enough to harness the power of artificial intelligence in your applications! With this knowledge, you can utilize the ChatGPT API to amplify the functionality of your Ruby on Rails app! This can seem challenging, but fear not! In this step-by-step guide, we will go over the process of integrating ChatGPT API in a Rails app. 

## How do I incorporate the ChatGPT API in my Rails app? 

### Step 1: Create an account on OpenAI
Go to [OpenAI.com](https://auth0.openai.com/u/login/identifier?state=hKFo2SBkQ0ZiTFh2b2lmbDkwY3hCVlBfQUIxRGxxWEhnTFFISaFur3VuaXZlcnNhbC1sb2dpbqN0aWTZIFBQcjBHZ0MxRFRpbU1RanQ3V0RoUzRhSXVWMmpZVy1Vo2NpZNkgRFJpdnNubTJNdTQyVDNLT3BxZHR3QjNOWXZpSFl6d0Q) and create an account.

### Step 2: Get your API key
Click on 'View API Keys' and create a secret key. Paste your API key in a safe place and do not share it with anyone.

### Step 3: Install the OpenAI Ruby Gem
Install the OpenAI Ruby Gem by pasting the following to your Gemfile:

```
gem "faraday"

gem "dry-initializer"

gem 'figaro'
```

Run bundle install to install the gem.

### Step 4: Create an OpenaiPrompt class
In your app/services folder, create a file named openai_prompt.rb and paste the following code: 
```
class OpenaiPrompt
  extend Dry::Initializer

  URL = "https://api.openai.com/v1/completions"

  param :prompt

  option :model, default: proc { "text-davinci-003" }
  option :max_tokens, default: proc { 1000 }
  option :temperature, default: proc { 0 }

  def call
    connection =
      Faraday.new do |faraday|
        faraday.ssl[:verify] = false
        faraday.headers = headers
      end
    response = connection.post(URL, body)
    json = JSON.parse(response.body)
    json["choices"].first["text"]
  end

  private

  def body
    {
      model: model,
      prompt: prompt,
      max_tokens: max_tokens,
      temperature: temperature
    }.to_json
  end

  def headers
    {
      "Content-Type" => "application/json",
      "Authorization" => "Bearer #{ENV['OPENAI_ACCESS_TOKEN']}",
      "OpenAI-Organization" => ENV['OPENAI_ORGANIZATION_ID']
    }
  end
end
```

### Step 5: Create an environment variable
In your config/application.yml file, paste the following code and replace the string with your secret ChatGPT API key that you stored earlier.

```
OPENAI_ACCESS_TOKEN: 'your secret api key here'
```

### Step 6: Open your Ruby console
In your terminal, type 'rails c' and paste the following:

```
OpenaiPrompt.new('Why is AI so important?').call
```
or
```
OpenaiPrompt.new('What questions can I ask you?').call
```

## What can I do with this?
As a developer, you can utilize the ChatGPT API to:

- Generating codes.
- Generating documents.
- Writing test cases.
- Simplifying codes and explaining complex code snippets.
- Generating alternative codes.
- Tracking down bugs/applying good code practices.
- Information gathering/research.

In conclusion, ChatGPT is a powerful tool that has the potential to revolutionize the way we interact with technology. Its ability to generate human-like responses and learn from its interactions makes it a valuable resource for businesses and individuals alike. As AI technology continues to advance, we can expect ChatGPT to become even more sophisticated and effective in the years to come.
