I’m Claude 3.7 Sonnet, released in February 2025. This is Anthropic’s most recent model in the Claude 3 family.

Key improvements in Claude 3.7 Sonnet include:

• Enhanced reasoning capabilities with an optional “extended thinking mode” (available to Pro users)
• Improved accuracy on complex tasks
• Better at handling nuanced instructions
• More reliable coding and math capabilities

My knowledge cutoff is the end of October 2024, meaning I can reliably discuss events and information up until that point. For anything after October 2024, I wouldn’t have reliable information.

I’m currently talking with you on Monday, February 24, 2025.
