OpenAI ChatGPT API is a light-weight Ruby wrapper for the Rubyists. It gives nice struct objects for completions of the chatgpt, even the raw responses are returned in nice open struct objects. It uses Faraday for HTTP requests.

It supports all models of gpt-4 and gpt-3.5

You can get API for the chatgpt by doing the following here.

Configuration

require 'openai_chatgpt'
client = OpenaiChatgpt::Client.new(api_key: ENV['CHATGPT_API_KEY'])

Params:

• api_key: String - Required - The API key for the openai chatgpt api.

Response:

#<OpenaiChatgpt::Client:0x00000001055fc318 @adapter=:net_http, @api_key="YOUR_API_KEY", @stubs=nil>

Get completion text

resp = OpenaiChatgpt::Client.new(api_key: "fake").completions(
  messages: [
    {role: "user", content: "Hello, how are you?"},
    {role: "assistant", content: "I am good, how are you?"},
    {role: "user", content: "What is your name?"},
  ]
)

Params:

• messages: Array[String] - Required - Messages to generate response for [{role: "user", text: "Hello"}, {role: "bot", text: "Hi"}]
• model: String - Optional - Default: "gpt-4" - Model to use for generating response ["gpt-4", "gpt-4-0314", "gpt-4-32k", "gpt-4-32k-0314", "gpt-3.5-turbo", "gpt-3.5-turbo-0301"]
• temperature: Float - Optional - Default: 1.0 - Temperature for response generation between 0.0 and 2.0
• top_p: Float - Optional - Default: 1.0 - Top p for response generation between 0.0 and 1.0
• n: Integer - Optional - Default: 1 - Number of responses to generate
• stream: Boolean - Optional - Default: false - Stream response
• stop: Array[String] - Optional - Default: nil - Stop sequence for response generation
• max_tokens: Integer - Optional - Default: 4096 - Maximum number of tokens to generate
• presence_penalty: Float - Optional - Default: 0.0 - Presence penalty for response generation between -2.0 and 2.0
• frequency_penalty: Float - Optional - Default: 0.0 - Frequency penalty for response generation between -2.0 and 2.0
• logit_bias: Hash - Optional - Default: nil - Logit bias for response generation
• user: String - Optional - Default: nil - User for response generation

Response:

resp.results
=> [#<OpenaiChatgpt::Choice:0x0000000107abca68 @content="I am an AI language model created by Open", @index=0, @role="assistant">]

resp.usage
=> #<OpenaiChatgpt::Usage:0x0000000107aba808 @completion_tokens=10, @prompt_tokens=36, @total_tokens=46>

Also raw_response is available if you want the raw response from the API. This is useful if you want to do something with the raw response. Also that response is in OpenStruct Object which is a nice wrapper for the raw response and you can use 'dot' notation.

Error Handling

begin
  client.completions(messages: [{role: "user", text: "Hello, how are you?"}]) # this should be content instead of text
rescue OpenaiChatgpt::Error => e
  puts e.message
end
