How RubyLLM Works

RubyLLM provides one beautiful Ruby API for all LLM providers. Same interface whether using GPT, Claude, Gemini, or local Ollama models.

1. One API for Everything

# Chat with any provider - same interface
chat = RubyLLM.chat(model: 'gpt-4.1')
chat = RubyLLM.chat(model: 'claude-sonnet-4-5')
chat = RubyLLM.chat(model: 'gemini-2.0-flash')

# All return the same RubyLLM::Message object
response = chat.ask("Hello!")
puts response.content

2. Configuration First
