CustomGPTs currently run on GPT-4o, not o1, regardless of your subscription tier for now, including the Pro plan. This applies even though Pro offers access to advanced models like o1 for general use.
You can check out OpenAI’s help post for the current model GPTs are operating on.
Why Are CustomGPTs Limited to GPT-4o?
CustomGPTs use GPT-4o to balance functionality and scalability across all subscription levels. This limitation ensures efficient resource usage and consistent performance for all users, whether on Free, Plus, or Pro plans.
Is GPT-4o Good Enough for Your Needs?
Despite not being as advanced as o1, GPT-4o provides robust capabilities for:
- Content creation: Generating high-quality text for various purposes.
- Customer support: Delivering tailored, reliable responses.
- Educational tools: Assisting in structured learning and tutoring.
Can You Switch CustomGPTs to o1?
No, CustomGPTs are restricted to GPT-4o at this time. Even Pro users cannot configure CustomGPTs to use o1.
For Advanced Needs
If your tasks require the enhanced reasoning and precision of o1, use Pro plan features directly instead of CustomGPTs. This approach ensures access to o1’s full capabilities.
ChatGPT Pro: Will Your GPTs (CustomGPTs) Use o1 or 4o?
CustomGPTs currently run on GPT-4o, not o1, regardless of your subscription plan. Even Pro users cannot configure CustomGPTs to use the o1 model. This distinction is essential for anyone considering ChatGPT Pro for advanced CustomGPT capabilities.
Why Are CustomGPTs Restricted to GPT-4o?
CustomGPTs rely on GPT-4o to maintain consistency and scalability for all users, from Free to Pro plans. This ensures equitable access without overloading resources. While GPT-4o is a robust model, it is designed to be more resource-efficient than o1.

What Can GPT-4o Handle?
GPT-4o delivers reliable performance for a variety of use cases:
- Text creation: Crafting emails, blog posts, or scripts.
- Problem-solving: Addressing customer inquiries or educational queries.
- Scalable usage: Balancing quality with computational efficiency.
Although not as advanced as o1, GPT-4o is highly capable for most general tasks.
Can You Upgrade CustomGPTs to o1?
No, CustomGPTs cannot currently use o1. Even with Pro access, the tools used to build and run CustomGPTs are limited to GPT-4o. For tasks requiring o1’s advanced reasoning, you’ll need to utilize the Pro plan’s direct access to the o1 model outside of CustomGPTs.
How to Get the Most Out of CustomGPTs on GPT-4o
- Be specific with instructions
Customize your GPT’s behavior and scope by detailing its instructions in the Configure tab. - Leverage contextual data
Upload up to 20 files to enhance your GPT’s understanding of specialized topics or datasets. - Enable optional features
Utilize web browsing, DALL·E image generation, and advanced data analysis if supported by your plan. - Guide users with prompts
Include example prompts to help users interact effectively with your CustomGPT. - Set realistic expectations
Understand that GPT-4o has limitations compared to o1 and tailor your use cases accordingly.
Common Questions About CustomGPTs
Can I Use CustomGPTs for Advanced Business Applications?
Yes, but only for tasks within GPT-4o’s capabilities. For advanced problem-solving, consider using o1 directly with your Pro plan.
Are CustomGPTs Hard to Set Up?
No. Creating a CustomGPT is straightforward. Visit Creating a GPT for step-by-step instructions.
What If I Need o1 Capabilities?
If your requirements exceed GPT-4o’s limits, such as deep analytical reasoning or solving complex technical problems, you should access o1 directly. This feature is available to Pro users and provides the full computational power of OpenAI’s most advanced model.
