Claude on Question 11, Sep 23

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 string claude-sonnet-4-5), 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 end somewhat earlier than that, and I won't know about events after it.
