Show HN: RubyLLM 1.0 – A Beautiful Ruby Way to Work with AI

RubyLLM provides a unified interface to OpenAI, Anthropic, Google, and DeepSeek models with a clean, elegant API that feels like Ruby.

What makes it different?

Beautiful interfaces:

    chat = RubyLLM.chat
    embedding = RubyLLM.embed("Ruby is elegant")
    image = RubyLLM.paint("a sunset over mountains")

Works with multiple providers through one API:

    # Start with GPT
    chat = RubyLLM.chat(model: 'gpt-4o-mini')
    # Switch to Claude? No problem
    chat.with_model('claude-3-5-sonnet')

Streaming that makes sense:

    chat.ask "Write a story" do |chunk|
      print chunk.content  # Same chunk format for all providers
    end

Rails integration that just works:

    class Chat < ApplicationRecord
      acts_as_chat
    end

Tools without the JSON Schema pain:

    class Search < RubyLLM::Tool
      description "Searches our database"
      param :query, desc: "The search query"
      
      def execute(query:)
        Document.search(query).map(&:title)
      end
    end

It supports vision, PDFs, audio, and more - all with minimal dependencies.
