Using GenAI in Ruby on Rails

 

🧠 What is GenAI?

Generative AI (GenAI) refers to AI systems that can generate content — like text, images, code, or even audio — rather than just analyzing or classifying data. Popular examples include ChatGPT, DALL·E, and Stable Diffusion.

In a Ruby on Rails project, you can use GenAI to:

• Build chatbots for customer support.

• Generate product descriptions or blog posts dynamically.

• Enhance search features with natural language understanding.

• Create summaries of long documents.

• Automate email replies or notifications.

⚙️ Using GenAI in Ruby on Rails

The most common way is to connect Rails with OpenAI’s API (or other GenAI providers like Anthropic, Cohere, Stability AI).

Example: Text Generation with OpenAI (GPT-4o-mini)

# app/services/genai_service.rb
require "openai"

class GenaiService
  def initialize
    @client = OpenAI::Client.new(access_token: Rails.application.credentials.dig(:openai, :api_key))
  end

  def generate_text(prompt)
    response = @client.chat(
      parameters: {
        model: "gpt-4o-mini",
        messages: [{ role: "user", content: prompt }],
        temperature: 0.7
      }
    )
    response.dig("choices", 0, "message", "content")
  end
end

Usage in a controller:

class GenaiController < ApplicationController
  def create
    prompt = params[:prompt]
    ai = GenaiService.new
    render json: { result: ai.generate_text(prompt) }
  end
end

Example: Image Generation with DALL·E

def generate_image(prompt)
  response = @client.images.generate(
    parameters: {
      prompt: prompt,
      size: "512x512"
    }
  )
  response.dig("data", 0, "url")
end
