What Text AI Cannot Do
- ❌ Access real-time information (unless specifically enabled)
- ❌ Access the internet (unless enabled)
- ❌ Remember past conversations (each chat is separate)
- ❌ Always be correct (they make mistakes!)
- ❌ Have personal opinions (they simulate opinions)
- ❌ Access your files (unless you upload them)
How They Actually Work (Simple Version)
- Training: The AI "reads" billions of pieces of text from the internet
- Patterns: It learns patterns about how words go together
- Generation: When you ask something, it predicts what words should come next
- Response: It creates a response word by word
Think of it like autocomplete on your phone, but incredibly advanced!
