GPT-5 and the unified model

0:00 In this guide, we'll break down everything that's new in GPT5, from its unified model design to new superpowers like giant memory, advanced coding, and more. And by the end, you'll know exactly how to make the most of its new features. So, let's dive in. One of the first things you'll notice is that Chad GBT now has just one GPT5 model option. No more guessing between GBT4, 40, 03 Pro, or other models. GPT5 unifies all those into single model.

0:47 So, the confusion model picker menu is gone. Why is this a big deal? Previously, users had to manually switch models for different tasks. For example, a reasoning model for step-by-step logic versus a creative model for writing. Now, GBT5's main brain automatically does it all. Behind the scenes, OpenAI builds a smart router that decides when GBT5 should think harder using chain of thought reasoning. Just open Chad GBT and start a new chat. There's no drop down to toggle models anymore.

1:10 For example, I typed a question, "How can I improve customer engagement on my website?" GBT5 gave a quick structured answer. If I ask a follow-up question like, "Can you analyze this data for me?" The same model seamlessly handles it, possibly invoking its reasoning mode behind the scenes. If you need a quick and simple answer in reasoning mode, you can choose at any time by clicking the pop-up. No manual switch, and needed one model to rule them all.

1:34 GBT5 also dramatically expands the amount of information. All GBT5 models can accept a maximum of 272,000 input tokens and emit a max of 128,000 reasoning and output tokens. For a total
