2. Super User
After gaining hands-on experience with the Generative AI tools, the second step is improvising our knowledge and learning to use the tools better.
Generative AI tools have a lot of potential, which are not yet explored. To use them effectively, we need to learn to apply the right techniques. Most of the Generative AI tools generate responses based on the natural description known as prompt. Prompt writing is an art. We need to learn about prompt engineering in detail to explore Generative AI to its full potential. Here’s what you need to do for it:
