Claude on Question 11, Oct 1

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 access to a more granular internal version number or build identifier beyond that model name.
