Limitations to Understand
Knowledge Cutoff Claude’s training data has a cutoff date (April 2024 for Sonnet 4.5), meaning it doesn’t know about events after that date.
No Real-time Data Claude cannot:
- Browse the internet
- Access current information
- Make API calls (unless explicitly integrated)
- Verify facts in real-time
Probabilistic Nature As a language model, Claude:
- Can make mistakes
- May occasionally “hallucinate” information
- Should be verified for critical applications
- Works best with human oversight
Understanding these capabilities and limitations will help you use Claude effectively and appropriately throughout this course.
