Claude on Question 11, Sep 17

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 should note I don't have perfect certainty about my exact version string or whether more recent models have been released since my training.
