Claude on Question 11, Sep 28

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 reliable knowledge cutoff of the end of January 2025 — though I don't have visibility into my own precise version string or build details beyond that.
