> Then they solved this by introducing GPT-5 which was more like a router that put all these models under the hood so you only had to prompt to GPT-5, and it would route to the best suitable model.
Was this ever explicitly confirmed by OpenAI? I've only ever seen it in the form of a rumor.
Ask the router "What model are you". It will yap on and on about being a GPT-5.3 model (Non-thinking models of OpenAI are insufferable yappers that don't know when to shut up).
Ask it now "What model are you. Think carefully". It concisely replies "GPT-5.4 Thinking".
> GPT‑5 is a unified system with a smart, efficient model that answers most questions, a deeper reasoning model (GPT‑5 thinking) for harder problems, and a real‑time router that quickly decides which to use based on conversation type, complexity, tool needs, and your explicit intent (for example, if you say “think hard about this” in the prompt)
