Release notes

Sourced from ruby_llm's releases.

1.4.0

RubyLLM 1.4.0: Structured Output, Custom Parameters, and Rails Generators 🚀

We're shipping 1.4.0! This release brings structured output that actually works, direct access to provider-specific parameters, and Rails generators that produce idiomatic Rails code.

🎯 Structured Output with JSON Schemas

Wrestling with LLMs to return valid JSON is over. We've added with_schema that makes structured output as simple as defining what you want:

# Define your schema with the RubyLLM::Schema DSL
# First: gem install ruby_llm-schema
require 'ruby_llm/schema'
class PersonSchema < RubyLLM::Schema
string :name
integer :age
array :skills, of: :string
end
Get perfectly structured JSON every time
chat = RubyLLM.chat.with_schema(PersonSchema)
response = chat.ask("Generate a Ruby developer profile")
=> {"name" => "Yukihiro", "age" => 59, "skills" => ["Ruby", "C", "Language Design"]}

No more prompt engineering gymnastics. Just schemas and results. Use the RubyLLM::Schema gem for the cleanest DSL, or provide raw JSON schemas if you prefer.

🛠️ Direct Provider Access with with_params

Need to use that one provider-specific parameter? with_params gives you direct access:

# OpenAI's JSON mode
chat.with_params(response_format: { type: "json_object" })
     .ask("List Ruby features as JSON")

No more workarounds. Direct access to any parameter your provider supports.

🚄 Rails Generator That Produces Idiomatic Rails Code

From rails new to chatting with LLMs in under 5 minutes:

rails generate ruby_llm:install

This creates:
