This code queries OpenAI's API for valid SketchUp Ruby code and then executes it.

Call OpenAI API from SketchUp.rb

require 'net/http'
require 'uri'
require 'json'

# Set the endpoint and API key for the OpenAI API
endpoint = "https://api.openai.com/v1/chat/completions"
api_key = "<YOUR API KEY>"

# Set up the system message for the code completion
sys_message = "Generate only valid SketchUp Ruby code."

# Ask the actual prompt
prompt = "Draw a box"

# Set up the HTTP request with the API key and prompt
uri = URI(endpoint)
req = Net::HTTP::Post.new(uri)
req["Content-Type"] = "application/json"
req["Authorization"] = "Bearer #{api_key}"
req.body = JSON.dump({
  # Enter the AI model here
  "model" => "gpt-3.5-turbo",
  "messages" => [ 
      { "role" => "system", "content" => "#{sys_message}" }, 
      { "role" => "user", "content" => "#{prompt}" } 
  ],  
  "max_tokens" => 1024,
  "top_p" => 1,
  "n" => 1,
  "temperature" => 0.1,
  "stream" => false
})

# Make the HTTP request to the OpenAI API and parse the response
res = Net::HTTP.start(uri.hostname, uri.port, use_ssl: true) do |http|
  http.request(req)
end
response_body = JSON.parse(res.body)

# Get the generated code from the API response and clean it up a bit
generated_code = response_body["choices"][0]["message"]["content"]
generated_code.strip!
generated_code = generated_code[/```ruby(.*?)```/m, 1].strip! if generated_code.include? "```"

# Display the generated code in the Ruby console
p generated_code

# Run the generated code - fingers crossed!
eval generated_code
