Claude on Question 11, Sep 25

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 of early 2025 — though I can't verify which specific deployment or version you're accessing, and my knowledge of events close to that cutoff is less reliable than for earlier periods.
