What is GPT?
GPT (Generative Pre-trained Transformer) is the AI architecture developed by OpenAI that powers ChatGPT and many other AI applications.
GPT represents a family of large language models that learn to generate human-like text. The 'Generative' part means it creates new text. 'Pre-trained' refers to learning from massive text datasets before being fine-tuned. 'Transformer' is the neural network architecture that enables processing long sequences of text effectively. GPT models power ChatGPT, Microsoft Copilot, and countless other applications.
Why it matters
GPT matters because it's the foundation of the most widely-used AI systems. Understanding GPT helps you understand how AI assistants work, why different versions might describe your brand differently, and why AI can sometimes confidently state incorrect information. As GPT evolves, so does AI's ability to understand and discuss brands. Staying current with GPT developments helps anticipate changes in AI visibility.
What people get wrong
- GPT and ChatGPT are the same. GPT is the model; ChatGPT is a product that uses GPT. Many other products also use GPT models.
- All GPT versions are equally capable. Each version has different capabilities. GPT-4 significantly outperforms GPT-3.5 in reasoning and accuracy.
- GPT understands like humans do. GPT predicts statistically likely text patterns. It produces human-like output without human-like understanding.

Frequently Asked Questions
Which GPT version is best for my brand visibility?
GPT-4 has more knowledge and nuance. But focus on visibility across both 3.5 and 4, as many users access different versions.
When will GPT be updated with new information?
Major model updates happen periodically. Knowledge cutoffs mean recent information needs web-browsing features to access.
Does GPT 'remember' my brand across conversations?
No. Each conversation starts fresh. What GPT knows comes from training, not previous conversations about your brand.
Can I train GPT on my own content?
Not the base model. Custom GPTs can have specific knowledge, but this only affects those specific GPTs, not ChatGPT broadly.
