What is GPT? — A Complete Unveiling of its Core Technologies

The technical essence and development history of GPT

GPT (Generative Pre-trained Transformer) is a generative language model developed by OpenAI.Based on the Transformer architecture, it autonomously learns to understand and generate natural language using deep learning techniques and massive amounts of language data. Since the advent of GPT-1 in 2018, each generation of GPT has brought groundbreaking progress:

Version	Year of release	Parameter size	Milestone
GPT-1	2018	117 million	First generation of large language model
GPT-2	2019	1.5 billion	It can automatically generate paragraph text.
GPT-3	2020	175 billion	Multilingualism, reasoning, and comprehension skills greatly improved
GPT-4/4o	2023-24	≈1 mega (multimodal)	Multimodal AI capabilities including full text, speech, and images

GPT's core operating process

“The basic operating logic of the GPT model is "pre-training → fine-tuning → input/output".：

Pre-training:Teach machines language and knowledge using massive amounts of internet text.
Fine-Tuning:Specialized training for specific fields (such as medicine and law).
The user inputs the text, and the model immediately outputs high-quality text.

The difference between GPT models and other AI

Natural language interaction:It requires no framework and can freely handle complex conversations.
Multi-tasking adaptation:It integrates multiple uses such as writing, Q&A, programming, translation, and image generation.
Scalable multimodal:The GPT-4o can handle text, voice, image, and video input and output.
