FAQs

Do I need coding experience or technical background to take this course?

Absolutely not! We've designed this course specifically for business owners and marketers without technical backgrounds. All technical concepts are broken down into simple, visual steps anyone can follow.

What kind of business data do I need to have ready before starting?

You'll get the best results with customer service conversations, FAQs, product documentation, and marketing copy that reflects your brand voice. However, we'll show you how to work with whatever content you currently have available.

How much time will it take to create my first custom model?

Many students complete their first working model within a weekend of focused effort. The entire course can be completed in 1-2 weeks on average.

Do I need to purchase expensive software or AI tools for this course?

The only platform you'll need access to is OpenAI, which offers reasonable pricing based on your usage.

How is training a custom GPT model different from using prompt engineering with existing AI tools?

While prompt engineering can improve results with generic AI tools, it has significant limitations. Custom training embeds your specific knowledge, terminology, and voice directly into the model's parameters, resulting in much more accurate and consistent outputs. Your trained model will understand nuances about your business that would require complex prompting to achieve otherwise, and it maintains this knowledge without needing to repeat instructions with each interaction.

What kind of businesses benefit most from this course?

Businesses of all sizes can benefit, but we've seen the greatest impact for companies that have:
1) Repetitive customer communications that follow patterns,
2) Established brand voice and messaging that needs consistency,
3) Specialized knowledge or terminology that generic AI struggles with, or
4) Limited staff handling a high volume of inquiries.

Service businesses, e-commerce stores, consultancies, and content creators have all seen excellent results from implementing custom GPT models.

Can I create multiple custom models for different aspects of my business?

Absolutely! Once you master the process, you can create specialized models for customer service, content creation, internal processes, and more—each with its own unique voice and knowledge base.

How does this course stay current with OpenAI's rapidly changing platform?

Your enrollment includes lifetime updates to all course materials. As OpenAI's platform evolves, we update our tutorials and provide supplementary lessons to keep your skills current.

Can this help my business if we already use ChatGPT or similar AI tools?

Definitely! The difference between generic AI and a custom-trained model is dramatic. Your custom model will understand your specific products, services, tone, and business context in ways no generic AI ever could.

Is there any ongoing support after I complete the course?

Yes, you'll have access to our community forum where our instructors and fellow students provide feedback, answer questions, and share success stories. Many students find this ongoing support invaluable as they refine their AI implementation.
