How to Change ChatGPT Model from GPT-5 to GPT-4o?

For many ChatGPT users, especially those on the free plan, switching between GPT-4o and GPT-5 can be confusing. OpenAI’s free tier uses an automatic model selection system—meaning you don’t always have control over which model you get. If your account has defaulted to GPT-5, you might be looking for a way to switch back to GPT-4o, which is known for its fast performance, high accuracy, and balanced cost-efficiency. While OpenAI does not provide a direct model-switching option for free users, workarounds and official methods are available—especially if you understand how the platform functions. This comprehensive guide will walk you through using GPT-4o instead of GPT-5, whether on the free or Plus plan.

Understanding the Difference Between GPT-4o and GPT-5

Before we explore the switching process, it’s essential to understand the key differences:

• GPT-4o is optimized for speed and low-latency interactions while maintaining excellent reasoning ability.
• GPT-5 is a newer, more complex model that may handle specific reasoning tasks better but could sometimes feel slower.
• Free Plan Users don’t get permanent control over their model—OpenAI dynamically assigns models based on server load and testing needs.

Why Many Users prefer GPT-4

Many users actively seek GPT-4o because of its:

• Faster response time for casual and professional use.
• Lower computing resource demands often mean more uptime during peak hours.
• Consistent conversational tone, ideal for writers, developers, and researchers.
• Compatibility with URL-based model switching.

Method 1: URL Parameter Switching for GPT-4o

One of the easiest ways to switch to GPT-4o is by directly modifying the ChatGPT URL.

Step-by-Step Guide:

1. Log in to your ChatGPT account in your browser.
2. Replace your current ChatGPT URL with:
3. https://chatgpt.com/?model=gpt-4o
4. Press Enter and you’ll start a new chat with GPT-4o instantly.

For GPT-4o Mini, use:

https://chatgpt.com/?model=gpt-4o-mini

Note: This trick works only if GPT-4o is available to your account.

Method 2: In-App Model Selector (For Plus Users)

If you are a ChatGPT Plus subscriber, switching between models is straightforward.

How to Switch Models:

1. Open ChatGPT on desktop or mobile.
2. Look at the top of your chat window where the current model (e.g., “GPT-5”) is displayed.
3. Click the dropdown arrow or the model name.
4. Select GPT-4o from the list.

Method 3: New Chat Window Selection

You can also choose GPT-4o before starting a conversation.

Steps:

1. Click “+ New Chat” from the left sidebar.
2. Look at the model selector at the top of the chat page.
3. Select GPT-4o before typing your first message.

Method 4: Wait for OpenAI’s Automatic Model Switch

If you’re on the free plan, OpenAI might switch back to GPT-4o at different times based on:

• Server load
• Testing schedules
• User feedback

Tip: Try checking during non-peak hours (early mornings or late nights) when GPT-4o availability is higher.

Method 5: Sign in on Multiple Devices or Browsers

Sometimes GPT-4o might be accessible on one device but not another. If you can’t access it on your primary device:

1. Log in to ChatGPT using another browser.
2. Try the URL parameter method again.
3. Check if GPT-4o becomes available.

Method 6: Upgrade to ChatGPT Plus for Full Control

If GPT-4o access is crucial for your workflow:

• Subscribe to ChatGPT Plus.
• You’ll get manual model selection every time.
• No need to wait for OpenAI’s automatic changes.

Troubleshooting When GPT-4o Isn’t Showing Up

If you cannot find GPT-4o:

• Make sure you are signed into the correct account.
• Clear your browser cache and cookies.
• Log out and log back in.
• Try incognito mode for a clean session.
• Check OpenAI’s status page for server issues.

Advantages of Using GPT-4o Over GPT-5 in Certain Scenarios

Even though GPT-5 is technically more advanced, GPT-4o may be better for:

• Rapid ideation and brainstorming
• Customer service chatbots
• High-volume content creation
• Programming assistance with low-latency output

Wrap Up

While OpenAI’s free plan doesn’t offer a permanent switch option for GPT-4o, URL-based tricks, timing strategies, and subscriptions can give you control over your AI experience. By following the abovementioned methods, you can maximize your chances of using GPT-4 whenever you need its speed, efficiency, and reliability.
