A Generative AI course is designed to teach learners how to understand, develop, and apply AI models that can create new content such as text, images, music, and even code. Unlike traditional AI, which is primarily used for tasks like classification or prediction, generative AI focuses on producing original data that mimics real-world inputs based on training data.

Training a generative AI (Gen AI) model and using a pre-trained one are two different approaches to building AI-powered solutions, each with distinct goals, processes, and resource requirements.

Training a Gen AI model involves building the model from scratch or fine-tuning it on specific data. This process requires large datasets, significant computational power, and deep expertise in machine learning. Training from scratch allows full customization and control over the model’s behavior, making it ideal for unique applications or proprietary use cases. However, it’s resource-intensive, time-consuming, and costly.

Using a pre-trained model means leveraging a model that has already been trained on large datasets, often by organizations with extensive resources (e.g., OpenAI, Google). These models, like GPT or BERT, have broad language understanding and can be fine-tuned or used as-is through APIs. This approach is much faster and more accessible, allowing developers to build powerful applications with minimal effort and cost. It’s ideal for most businesses that need robust AI without the overhead of custom training.

In summary, training a model offers customization but requires heavy resources, while using a pre-trained model provides ease, speed, and cost-efficiency for a wide range of tasks.
