[NLP] New foreign trends--LLM model

1. Description

        What is the trend of NLP? This is an article in a series about using large language models (LLMs) in practice. Here, I'll introduce LLMs, and introduce the 3 levels at which they are used. Future articles will explore the practical aspects of LLM, such as how to use OpenAI's public API, the Hugging Face Transformers Python library, how to fine-tune an LLM, and how to build an LLM from scratch.

2. What is LLM?

        LLM is short for Large Language Model , the latest innovation in AI and machine learning. This powerful new AI is all the rage in November 2022 with the release of ChatGPT.

        For those enlightened enough to live in a world outside of the AI ​​buzz and tech news cycles, ChatGPT  is a chat interface running on an LLM called GPT-3 (now upgraded to GPT-3.5 at the time of writing) or GPT-4).

        If you've used ChatGPT, it's obvious that this is no match for AOL Instant Messenger 's traditional chatbot or credit card customer service.
