AI Fundamentals

Definition

GPT (Generative Pre-trained Transformer) is the architecture behind ChatGPT, developed by OpenAI. It is a language model pre-trained on vast text corpora that can be used to generate content, answer questions, and perform complex text tasks. GPT-4 and subsequent versions have demonstrated increasingly advanced reasoning capabilities.

Transformer

The Transformer is the neural network architecture introduced by Google in 2017 that revolutionized AI. It uses a mechanism called 'attention' to process data sequences in parallel rather than sequentially. Virtually all modern language models (GPT, Claude, Gemini, LLaMA) are based on this architecture.

Tools & Platforms

ChatGPT

ChatGPT is the OpenAI AI application based on GPT models that brought generative AI to the mainstream. It enables natural language conversations, content generation, data analysis, and image creation. For SMEs, it is often the first point of contact with AI: from brainstorming to drafting emails, from translation to report analysis.

Tools & Platforms

OpenAI

OpenAI is the company that developed ChatGPT, GPT-4, DALL-E, and Whisper. It is the leading AI model provider via API, with millions of developers and companies integrating its models into their products. For SMEs, OpenAI APIs offer access to advanced AI capabilities with pay-per-use pricing, without the need for proprietary AI infrastructure.

Artificial Intelligence

Artificial intelligence is the computer science discipline that develops systems capable of performing tasks that normally require human intelligence: understanding language, recognizing images, making decisions. For Italian SMEs, AI represents a concrete opportunity to automate repetitive processes and achieve measurable competitive advantages.

Machine Learning

Machine learning is a subfield of AI in which systems automatically learn from data without being explicitly programmed for every scenario. ML algorithms analyze patterns in historical data to make predictions on new data. In business practice, it is used to forecast demand, classify documents, and optimize production processes.

Deep Learning

Deep learning is an advanced machine learning technique that uses neural networks with many layers (hence 'deep') to learn complex data representations. It underpins modern speech recognition, machine translation, and text generation systems. It requires large amounts of data but produces extraordinarily accurate results.

Neural Network

An artificial neural network is a computational model inspired by the workings of the human brain, composed of nodes (neurons) organized in interconnected layers. Each connection has a weight that is adjusted during training. Neural networks underpin nearly all modern AI systems, from image recognition to text generation.

Language Model

A language model is an AI system trained on enormous amounts of text to understand and generate natural language. Large language models (LLMs) such as GPT and Claude can write texts, answer questions, translate, and reason about complex problems. For businesses, they represent versatile assistants for any text-based task.
