Generative AI models use complex algorithms and neural networks to autonomously generate new, original content such as images, text, videos and music. These models include variational autoencoders, generative adversarial networks, transformer-based models and neural radiance fields. Generative AI has applications in industries like art, design, healthcare, cybersecurity, and gaming where it can supplement operations by producing images, text, code documentation and more. However, challenges remain around preventing the generation of harmful content, addressing bias, attributing sources, protecting privacy, and reducing energy consumption of these technologies.
