ChatGPT

ChatGPT is an iconic AI tool developed by OpenAI and belongs to the Text Generation/Natural Language Processing (Text Generation/NLP) category. It is based on Large Language Models (LLMs, e.g., the GPT family) that process and generate text in a natural conversational way to help users with a variety of linguistic tasks. Launched at the end of 2022, it has evolved into multimodal versions (e.g., support for images and speech) and is widely used in everyday and professional applications.

Key features and functionality:

1. Text generation:
   • Generate articles, stories, code, emails or creative content based on user prompts. For example, type “Write a short story about space travel” and it will output a full narrative.
   • Supports multiple rounds of dialog, remembers context, and provides coherent responses.
2. Natural Language Processing (NLP):
   • Translation and summarization: translate language in real time, or extract summaries from long texts.
   • Q&A & Analytics: answer questions, analyze emotions, and explain complex concepts (e.g., programming or scientific knowledge).
   • Role-playing: simulate an expert, teacher, or virtual assistant for interactive teaching or customer service support.
3. Advanced Extensions:
   • Integrated plug-ins (e.g. GPT-4o for image generation and analysis).
   • Customized GPT: Users can create proprietary versions for use in specific areas such as education or programming.

Application Scenarios:

• Content creation: writing assistant, brainstorming ideas.
• Education and learning: explaining knowledge, generating practice questions.
• Business: customer service chat, marketing copywriting, data analysis assistance.
• Entertainment: chat, game plot generation.

ChatGPT is available as a free basic version (with usage limits), with premium versions (such as Plus/Pro) offering stronger models and unlimited access. As a pioneer in the field of NLP, it has driven the popularization of AI conversation systems.

Application Restrictions:

ChatGPT is currently restricted from accessing use in China and other regions.
