Overview

The LLM::OpenAI::Responses class provides a responses object for interacting with [OpenAI’s response API](platform.openai.com/docs/guides/conversation-state?api-mode=responses). The responses API is similar to the chat completions API but it can maintain conversation state across multiple requests. This is useful when you want to save bandwidth and/or not maintain the message thread by yourself.

Examples:

#!/usr/bin/env ruby
require "llm"

llm = LLM.openai(ENV["KEY"])
res1 = llm.responses.create "Your task is to help me with math", :developer
res2 = llm.responses.create "5 + 5  = ?", :user, previous_response_id: res1.id
[res1,res2].each { llm.responses.delete(_1) }

Instance Method Details

#create(prompt, role = :user, model: "gpt-4o-mini", **params) ⇒ LLM::Response::Output

Create a response

Parameters:

• params (Hash) —

  Response params

• prompt (String) —
