⚠️ Common Issues with Generative AI

🚀 Generative AI Applications

🌱 Generative AI Model Types Explained

🧠 How Generative AI Works

A prompt is a short input text given to a Large Language Model (LLM) to guide its output.<ul><li class="ql-align-justify">Example: “Summarize this article,” or “Write a poem in the style of Shakespeare.”</li><li class="ql-align-justify">Prompt design is the art of crafting effective prompts to achieve desired outcomes from the model.</li></ul>

✏️ Prompting

Generative models create new data, while discriminative models learn to tell data apart.

<ul><li class="ql-align-justify">No tags or labels on the data</li><li class="ql-align-justify">The goal is to explore and find patterns or groups in the raw data</li></ul>

Machine Learning Model - Unsupervised

<ul><li class="ql-align-justify">Takes text as input</li><li class="ql-align-justify">Can generate more text, images, audio, or even make decisions</li><li class="ql-align-justify">It learns language patterns from training data</li><li class="ql-align-justify">Predicts how to complete or respond to a sentence</li></ul>
