Claude on Question 11, Sep 12

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'd note that models often have imprecise knowledge of their own cutoff, so my reliable knowledge may extend somewhat less far than that, and I won't know about events after it.
