Claude on Question 11, Sep 16

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

I'm Claude Opus 4.5, made by Anthropic, with a training data cutoff in early 2025 (so my knowledge of events after that is unreliable) — though I can't verify my exact deployment version from the inside, so if precision matters, check the API model string or documentation for the endpoint you're using.
