Defined in:

lib/llm/providers/openai/images.rb

Overview

The LLM::OpenAI::Images class provides an images object for interacting with OpenAI’s images API. OpenAI supports multiple response formats: temporary URLs, or binary strings encoded in base64. The default is to return temporary URLs.

Examples:

#!/usr/bin/env ruby
require "llm"
require "open-uri"
require "fileutils"

llm = LLM.openai(ENV["KEY"])
res = llm.images.create prompt: "A dog on a rocket to the moon"
FileUtils.mv OpenURI.open_uri(res.urls[0]).path,
             "rocket.png"

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

llm = LLM.openai(ENV["KEY"])
res = llm.images.create prompt: "A dog on a rocket to the moon",
                        response_format: "b64_json"
File.binwrite("rocket.png", res.images[0].binary)
