Claude on Question 11, Sep 13

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, made by Anthropic, with a training data cutoff of roughly early 2025 — though I can't independently verify which exact model version is serving this conversation, and my knowledge of events near the cutoff tends to be spotty.
