OpenAI Says GPT-5 Is One-Size-Fits-All; New Open Model Was Cheap to Train

OpenAI unveiled its new flagship AI model, GPT-5, on Thursday. And with the launch, OpenAI seems to be moving more towards offering an entire AI system to its customers versus giving them the choice between models. The company said during a live-streamed presentation that it would be withdrawing user access to its older models, meaning that customers won’t be able to choose between models depending on how much they want to spend or how complex the task is. 

Instead, GPT-5 will make that choice by itself by deciding how long it will “think” (i.e. how much compute it will use) when faced with tough questions.
