ChatGPT Models, Explained: How To Use Each (2024)

Confused with the bar at the top of ChatGPT?

You may be wondering…

What is ChatGPT-3, 3.5, 4? What does all that mean?

In this guide, we’ll answer all of your concerns.

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.

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.

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.

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

1. Click on the model you want to use.
2. Get back to the “Send a message” box.
3. 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

In this example, we’re using the “regular” GPT-4 model.

Not plugins, just the GPT-4 version for most purpose.

The different ChatGPT models
