Let’s check it out, step by step.
What are ChatGPT models?
ChatGPT models are machine learning models designed to generate human-like text based on the data they’ve been trained on.
The better the model, the better and more useful the response.
![List of the current ChatGPT Models](https://guides.ai/wp-content/uploads/2023/10/List-of-the-current-ChatGPT-Models-1024x576.webp)
The idea is to:
- Feed the model some input text
- And it will generate a relevant and coherent response
It’s not just spitting out memorized answers — it’s generating text based on the patterns it’s learned.
That’s why we train ChatGPT with custom data.
How to select a model in ChatGPT
You can select a model in ChatGPT by starting a new chat, clicking on the bar at the top, and selecting your preferred model.
Note: ChatGPT doesn’t allow you to change the model mid-conversation. You have to start over if you want to change the model.
Below is the step-by-step process to select a model.
1. Open ChatGPT
The 2 most popular scenarios are:
- You’re already in ChatGPT → Then you have to start a new conversation
- You’re not there yet → Open the app by going to chat.openai.com
That is the official ChatGPT address.
![ChatGPT - Model Selection Buttons](https://guides.ai/wp-content/uploads/2023/11/Starting-a-new-chat-with-ChatGPT-1024x576.webp)
Simply open a new conversation and don’t send am message just yet.
2. See your Models
At the top of the page, you’ll see these two buttons:
- GPT-3.5
- GPT-4
Hover your mouse on them — they tell information about the model you’re currently using.
![ChatGPT - Model Selection Buttons](https://guides.ai/wp-content/uploads/2023/11/ChatGPT-Model-Selection-Buttons-1024x576.webp)
If you hover above GPT-3.5, it will say:
“Our fastest model, great for most every day tasks.”
– OpenAI
This is available Free and Plus users.
However, if you have ChatGPT Plus, you can also access GPT-4.
Let’s see how to do it.
3. Change models
- GPT-3.5 is a single model
- GPT-4 has a few plugins
Simply click on the Model/Plugin you want to use
![ChatGPT - All Available Models](https://guides.ai/wp-content/uploads/2023/11/ChatGPT-All-Available-Models-1024x576.webp)
- Click on the model you want to use.
- Get back to the “Send a message” box.
- Start chatting.
ChatGPT will tell you which model you’re using once you send a message.
You can use GPT-4 plugins only if you’re a Plus subscriber.
How do you know which model you’re using?
- You’ll notice a bar at the top — it goes away when scrolling down
- You can even ask ChatGPT which
![How to know which ChatGPT Model you're using](https://guides.ai/wp-content/uploads/2023/11/How-to-know-which-ChatGPT-Model-youre-using-1024x576.webp)
In this example, we’re using the “regular” GPT-4 model.
Not plugins, just the GPT-4 version for most purpose.
