Tweet about GPTs

Is it just ChatGPT with a specified name? Is it just a customized version of ChatGPT with predefined prompts? If yes, what’s the point?

All the points above are exactly the point of GPTs.

GPTs are specific. And that’s their biggest strength. Sure, you can prompt ChatGPT to respond, but then you have to know the right prompts and understand how to obtain the output you want and feed the data you expect from it.

What you had to do earlier:

  • Understand the right prompt to use or find a prompt from OpenAI experts to help you
  • Create custom instructions to ensure your answers presume certain characters, like writing like a copywriter
