What is ChatGPT?

ChatGPT is a large language model developed by OpenAI that can understand human language and generate high-quality responses. Since its release in November 2022, ChatGPT has become one of the world’s most popular AI applications, with hundreds of millions of users.

Why is ChatGPT So Popular?

Practical Tips: How to Use ChatGPT Better

2. Ask Step-by-Step

For complex tasks, break them down into smaller questions to solve progressively.

3. Request Specific Formats

You can ask ChatGPT to output content in tables, lists, code, or other specific formats.

4. Engage in Multi-Turn Conversations

If the answer isn’t ideal, continue asking follow-up questions or request modifications.

Common Use Cases

Work Scenarios

Important Considerations

ChatGPT’s Limitations

1. Knowledge Cutoff Date: Training data has a time limit; it doesn’t know recent events
2. May Make Mistakes: Generated content needs human verification
