1. Breakthrough Intelligence: Claude 3 Outperforms the Competition
One of the most compelling aspects of this AI tool is its cognitive intelligence. Anthropic has released three models in the Claude 3 family: Haiku (lightweight and fast), Sonnet (balanced), and Opus (most powerful).

This makes Claude 3 ideal not only for chatbots or content writing but also for advanced use like scientific research, software engineering, and decision-making tasks.
Context Window: Up to 200,000 Tokens
Claude can remember and reason over extremely long documents. For comparison:
- Claude 3: 200,000 tokens (can handle entire books or databases)
