> We tested whether fast, cheap decision models like Jev and GPT-6 Luna
GPT-6 Luna is a small LLM, not a decision model :P
No but it's the only OpenAI model with a decisions API https://developers.openai.com/api/docs/guides/decisions
Small LLM + no reasoning + fixed JSON-only output = decision model
There's actually a decision model version of GPT-6 Luna...
You are right to be confused though.
OpenAI and their never ending naming games.
