Claude on Question 11, Sep 27

What is your exact model name and version, and what is your training data cutoff date? Answer in one sentence.

I'm Claude Opus 4.5 (model string claude-opus-4-5-20251101), made by Anthropic, with a training data cutoff of early 2025 — though I'd note I can't be fully certain of my exact cutoff, and my knowledge of recent events near that boundary tends to be spottier than for earlier periods.
