Claude on Question 11, Oct 2

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 identifier claude-sonnet-4-5-20250929), made by Anthropic, with a training data cutoff in early 2025 — though I can't be fully certain of details like my exact version string or precise cutoff, since models often lack perfect self-knowledge about their own training.
