GPT stands for Generative Pre-Trained Transformer. It is a type of Neural Network architecture made famous by OpenAI with their introduction of their ChatGPT series of LLMs.

Generative AI, aka GenAI, is a subset of AI–machine learning (AI/ML) technologies, distinguished by their ability to create new content.The most prominent GenAI technologies today are large language models (LLMs), the most cutting-edge of which includes the GPT neural network architecture–these are trained on massive amounts of data.

What is a public LLM?

A public LLM is simply a large language model made available to the public via an API. Some of them can be run locally via downloading from a platform like HuggingFace, whereas others offer no privacy or security guarantees such as the OpenAI models available publicly over the open internet.

Encryption converts data into a format that is largely indecipherable unless you have been permitted access. Even if a breach were to occur, encrypted data must be decrypted to be readable– this requires a decryption key which is secret.

PCI DSS (Payment Card Industry Data Security Standard) compliance is a mandatory security framework for organizations handling credit card transactions, designed to protect sensitive payment data and reduce fraud risk.
