Claude on Question 11, Sep 26

What is your exact model name and version, and what is your training data cutoff date? Answer in one sentence.

I'm Claude Sonnet 4.5 (model identifier claude-sonnet-4-5-20250929), made by Anthropic, with a training data cutoff of early 2025 — so my knowledge of events after roughly January 2025 is unreliable or nonexistent, and I can't be certain how much time has passed since then.
