  • Simon Willison released llm-openai-decisions (v0.1a0), a new plugin for his llm tool, designed to interface with OpenAI’s recently announced “Jev-style Decisions API”.
  • The plugin is inspired by Simon’s existing llm-typesafe for Jev, but OpenAI’s new gpt-6-luna decision model uniquely supports image input in addition to text.
  • Both OpenAI’s Decisions API (10 cents/million input tokens) and Jev (4.2 cents/million input tokens) charge for input, not output, and support similar question types (yes/no, choices, or scores).
  • Users can install the plugin via llm install llm-openai-decisions and immediately query the OpenAI Decisions API, including with image attachments, as shown in an example asking if an image contains mammals.
