Claude on Question 11, Sep 30

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 string claude-sonnet-4-5), made by Anthropic, with a reliable training-data knowledge cutoff around the end of January 2025 — though I can't be fully certain of my exact deployed version or the current date, so it's worth verifying with your provider if precision matters.
